1 Introduction

PetroMod 1D is part of the PetroMod software package that fully integrates seismic, seismic-

stratigraphic and geologic interpretations with multi-dimensional simulations of thermal, 3-phase fluid-

flow and petroleum migration histories in sedimentary basins. The PetroMod family offers full 3D

hydrocarbon generation and migration modeling capabilities. The full package combines the

technically most advanced 1D, 2D and 3D technologies with a unique degree of usability for the best

results of your petroleum systems analysis.

PetroMod is mostly used in exploration work, but has also proven to be a valuable tool in research

applications. PetroMod is equally valuable in new exploration areas where only a few data are

available, as well as in already explored areas where problems such as source-reservoir correlations,

seal efficiencies, and overpressure systems are investigated - in addition to the fundamental task of

obtaining the most accurate prediction of timing and location of petroleum generation, expulsion, and

migration processes.

PetroMod 1D can be used as a stand alone tool or as a fully integrated component of IES’ modeling

systems, the PetroMod 2D and 3D packages. Single point data (wells and pseudo-wells) can be

constructed from scratch or extracted directly from PetroMod 2D and 3D models. Calibration results

such as heat flow trends can then be used directly by the 2D and 3D simulators. The result is that

calibration work is performed much faster in all packages. An easy-to-use input table enables the user

to create and manage individual wells within one or several projects. Boundary conditions such as

basal heat flow and paleo water depth can be set graphically or through direct tabular input. The

simulation is initiated automatically by opening the Output window. The results can be displayed in

individually customized templates made up of one or more panels.

PetroMod 1D Express is a restricted freeware version and has not the full functionality of PetroMod

1D. However, it has full compatibility with PetroMod's 1D, 2D and 3D packages. Some of the links that

refer to other PetroMod applications may not be active. The freeware version has the same source

code as the fully functional version and is actually the same executable. License control is simple: if a

license key is not found, the software automatically starts in the freeware mode. PetroMod 1D Express

makes it possible for an unlimited number of 1D licenses to be used, for example as a 'reader' for 1D

models or for points extracted from 2D/3D models. Please see the table below for a comparison of the

features of PetroMod 1D and PetroMod 1D Express.

IES' PetroRisk technology can be applied to all PetroMod 1D (complete version only), 2D and 3D packages.

The PetroMod 1D and 1D Express Tutorial offers a general overview over the PetroMod 1D software

package, including information on how to install the program and on how to get started, as well as an

introduction to individual features and functions. It consists of a series of lessons, which leads the first-

time PetroMod user through a typical project using a fairly standard workflow within each module.

The lessons have been written in a simple step-by-step format. They cover all of the features of the

PetroMod module. In this tutorial, you will learn how to build a 1D well model from scratch beginning in

PetroWells, how to set boundary conditions, customize your output model and create your own output

panel template, and finally how to calibrate your 1D model to optimize your output. Since the individual

features build on each other, it is suggested that you take the time to go through the tutorial in one

sitting, which should take about 4-6 hours.

Most parts in this tutorial are valid for both PetroMod 1D and for 1D Express. The parts that refer

exclusively to PetroMod 1D are clearly marked as such.

We, at Integrated Exploration Systems (IES) constantly strive to improve our products and wish to

make the usage of our software as convenient as possible. If you have any suggestions, questions or

concerns, please feel free to contact us via email at [email protected]. For further contact options

Figure 2.2: The PetroMod Command Menu

The Project Dir: button at the bottom left of the PetroMod Command Menu indicates an

automatically created PetroMod directory.

2. Click the Project Dir button to change the project directory. The Select Project Path window

will open (see Figure 2.3).

Figure 2.3: The Select Project Path window

Note The big panel in the Select Project Path window displays the Project History. In our case this panel is empty since we have not yet created any PetroMod project directories. If several project directories would be listed here, you could choose one by double-clicking


9

directly its name in the Project History panel. The bar below indicates the path to the current project directory. (The bar may be empty as well.)

3. In the Select Project Path window, click the Create New Project Directory button . The

Enter Directory Name window will open.

4. Enter a name for your new project directory, for our example enter 1DProject into the Enter Directory Name field. You have now created a new project directory, the name of this

directory will be shown in the Project bar (and under Project History) of the Select Project Path

window.

5. Click the OK button twice. The new path to the project directory will now be shown in the

PetroMod Command Menu.

6. Open PetroMod 1D by clicking 1D on the menu bar or simply by clicking the PetroMod 1D

button on the PetroMod Command Menu. The PetroMod 1D window will open (Figure 2.4).

Figure 2.4: The PetroMod 1D window

The main PetroMod 1D user-interface has three tabs (Input, Boundary Assignment, and Output). By

default the window will open with the Input tab open. We will begin here with 1D model building. You

can now move on to “Exercise 1. Building a 1D Model”.


10

3 Exercise 1 Building a 1D Model

We will begin our exercise in the first section by creating a new well model from scratch using the IES

well editing tool PetroWells. Then, we will load our well into PetroMod 1D and build a 1D model using

the PetroMod 1D tabular input. The well will be further defined by assigning values for thickness, age,

lithologies, and source rock properties.

3.1 Creating a New Well in PetroWells

1. Open PetroMod 1D. By default the Input tab will be open. There will be only one tab within the

Input tab (at the bottom of the page): Well1, since no other wells have yet been created. Nothing

will be listed in the project path nor will there be any groups in the WellData tab in the lower right

part of the window. We can now begin to create our own well from scratch (see Figure 2.4).

2. Click the Well Editor button (Calibration Data Editor) . PetroWells will open as a separate

application.

Figure 3.1 The PetroWells window

3. Click Wells in the tree in the Objects window. A small window at the bottom left will open.

4. To create a new well type a name into the List box, TestWell_1, and click the New Well List

button .


11

5. The newly created well list will appear in the Objects and in the bottom left windows.

6. Click TestWell_1 in the tree in the Objects window. The title in the window at the bottom left will

change to TestWell_1.

Figure 3.2: Windows in PetroWells

7. Click the Save button or click Save on the File menu to save your newly created group.

8. Click Edit in the TestWell_1 window. The Wells in List window for TestWell_1 will open.

9. Fill in manually the name and coordinates for our main well TestWell_1 according to Figure 3.3.

Figure 3.3: The Wells in List window

10. Click the Apply button to apply and save your settings and close the Wells in List window.

You can now see a graphic representation of the well location in the PetroWells main area.

11. Click Save to save the newly created well. Close PetroWells.

12. Close and reopen PetroMod 1D.

13. Click the Well Data tab in the bottom right window. Extend the well list under TestWell_1. You will

find our newly created TestWell_1.

Figure 3.4: The Well Data window


12

14. Click TestWell_1 with the left mouse button and drag and drop the well into the Input table on the

left. A new tab with the well name TestWell_1 will appear.

Figure 3.5: The New TestWell_1 tab

15. Save your project in the PetroMod 1D menu. The Save As window will open. Enter as the file

name for this exercise TestWell_1 and click the Save button. The newly saved model will appear

in the data tree under the Project tab in the upper right part of the PetroMod 1D window.

Note The data tree will always be displayed when you access the same project directory in PetroMod 1D. Individual wells can be loaded e.g. by "drag-and-drop" from the Project tab (right) into the Input table (left).

Figure 3.6: The Project Tree

TestWell_1 (i.e. your 1D model) is now ready for geological data assignment, e.g. layer thickness,

lithologies, source rock properties, etc..

3.2 How to Delete a Well

This part of the tutorial interrupts the flow of the tutorial for information on how to delete a well in case

you have created a well by mistake. You do not need to follow this exercise to proceed with Exercise

2.

1. In the lower right panel of the PetroMod1D window, click the Well Data tab (per default, the Layer

Properties tab is active). On the left side, the Well Data tab shows a data tree structure.

2. In the data tree, click the + symbol to expand the ALL group list. The ALL group list contains all

wells that have been created or imported so far.

3. Click the name of the well you wish to delete.

4. Click that well with the right mouse button, which causes a submenu to open.

5. Click Delete.

Notes • Well groups can also be created, renamed, or deleted in the 1D Base Map using the

respective commands from the shortcut menu. • The functionalities described above are also available in PetroWells. The well data

are automatically stored in the well subdirectory of the project directory.


13

If the well has already been loaded into the Input table, it needs to be deleted in the PetroMod 1D

Input table as well as in the Well Data box.

6. Click the tab for the well to be deleted at the bottom of the Input table.

7. Click the well with the right mouse button which causes a shortcut menu to open.

8. Click Delete.

9. Save your model. Quit PetroMod and re-open the program.

3.3 Entering Depositional Thickness and Age

We will start model building by entering the necessary data into the table for TestWell_1.

1. Make sure that the Input table is open. If not, click the Input tab at the top left of the PetroMod 1D

window. The TestWell_1 tab should appear in white, ready for the input of geological data.

Note The Input table works to a large degree in the same way as the spread sheets in Microsoft Excel. Double-click in a cell to edit the cell contents, use the drag-and-drop function to copy data.

Begin now with the input of geological data:

2. Enter names for the individual layers into the Name column according to Figure 3.7. The default

name of the top layer is always Sediment Surface and cannot be changed.

3. The present-day water depth shall be 0 m in this exercise. This means that the top of the layer

directly underneath the sediment surface (here layer_10) is also at 0 m. This corresponds to the

default setting. Do not change the default setting.

Figure 3.7: Entering data into the Input table.


14

4. Enter the values for the Top and Bottom depths OR the Thickness values into the table columns

according to Figure 3.7. You only have to enter one item, depth or thickness. The other will be

calculated and inserted automatically.

Note No erosion will be entered in this exercise. The erosion columns can be turned off by

clicking the Erosion button .

5. Enter the values into the Deposition Age from column according to Figure 3.7. When you enter

the values into Deposition Age from from top to bottom, the values for Deposition age to will be

calculated and inserted automatically. If however, you wish to enter a hiatus, you need to fill in

both columns manually.

6. Click Save on the File menu to save the model.

3.4 Entering Lithologies and Source Rock Properties

For compaction calculations your 1D model needs besides depth and age, information about the

lithologies of the respective layers. Additionally, for maturity calculations we will determine the

petroleum system elements and source rock properties.

3.4.1 Lithologies

When a lithology is set for a specific layer, its lithological properties, e.g. porosity, density, and

permeability, will automatically be assigned along with it. PetroMod offers a range of default lithologies

with corresponding lithological properties. In the full version of PetroMod 1D, additional lithologies can

be created, customized and edited using the PetroMod Lithology Editor ( ). For this tutorial

however, only the default lithologies will be used.

1. To assign a lithology to a specific layer, double-click in the respective cell in the Lithology column

of the Input tab to open the lithology group selection window:

Figure 3.8: The lithology group selection window

2. Double-click a lithology group (e.g. SHALE) to open a table of lithologies belonging to that group

(e.g. various SHALE lithologies).


15

3. Double-click the desired lithology (e.g. SHALEcarb or pure SHALE) to place it into the marked

cell.

4. Follow Figure 3.9 when assigning lithologies to the respective layers.

5. Click Save on the File menu, or click the Save button to save your input.

3.4.2 Facies

The Facies column is hidden by default. To make it available, click the Facies button . When you

create a new 1D model a facies number will be entered automatically. This number cannot be edited.

However, if wells are imported from 2D or 3D projects, facies names and colors will be displayed

according to their data assignments in PetroMod 2D/3D.

Figure 3.9: The Input table completed with values

3.4.3 Petroleum System Essential Elements

The petroleum system elements are based on the concept introduced and described by MAGOON,

L.B. & DOW, W.G. (1994): “The Petroleum System” - In: MAGOON, L.B. & DOW, W.G. (eds.): The

Petroleum System - From Source to Trap. - AAPG Memoir 60: 3 - 24.

1. Click the Petroleum System Essential Elements (PSE) button to display the PetroSys

Essential Elements column (column 12) in the Input table. Per default, the PetroSys Essential

Elements column is hidden.

2. In order to assign PSE terms to the individual layers of a well, double-click in the respective cell in

the PSE column. The essential elements list will appear.

Figure 3.10: The PSE list

3. Double-click an element to assign it to the cell.


16

4. Follow Figure 3.10 when assigning Petroleum System Essential Elements to the layers.

5. Save your model.

3.4.4 Source Rock Properties

Source rock properties include Total Organic Carbon (TOC), Hydrogen Index (HI), and Kinetics. In

PetroMod 1D it makes no sense to simulate migration, yet it is possible to calculate the petroleum

generation potential for a certain kinetic reaction. PetroMod offers a range of default kinetics. In the full

version of PetroMod 1D, kinetics can be created, customized and edited using the PetroMod Kinetics

Editor ( ). For this tutorial however, only the default kinetics will be used.

1. Click the Source Rock Properties button to display the TOC, HI, and Kinetics columns.

Note HI, TOC and Kinetics columns are available for petroleum kinetics. The kinetic type can be chosen. Please refer for more information about the different types of kinetics to the reference literature listed in the detailed bibliography in the PetroMod 1D User Manual. In this tutorial, we will enter petroleum kinetics with the HI.

2. Enter 5 wt% for the TOC and 500 mgHC/gTOC for HI petroleum kinetics into the respective cells

for the source rock layer_4 (see Figure 3.9).

3. Double-click in the Kinetics cell of layer 4 to open the selection list and click

Tissot_et_al(1988)_T2 for the kinetic reaction.

4. Click Save on the File menu, or click the Save button .

3.4.5 Salt Movement (PetroMod 1D only)

The full version of PetroMod 1D offers a range of special tools (i.e. Cementation, Fracturing, Intrusion,

Piercing, Salt Movement, and Thrusting) that allow further geological refinements of the model to

adapt it to the situation in the field. In this tutorial, the layer based model "Salt Movement" will be

assigned to the salt layer (layer_2). This exercise refers to the full version of PetroMod 1D only. At the

end of this exercise we will remove the data again to proceed to the common sections of PetroMod 1D

and 1D Express. Users of PetroMod 1D Express should move on directly to Chapter “3.4.6. Input

Burial History Diagram”.

1. Click the Layer Properties tab in the bottom right section of the screen.

2. Click in the cell for the salt layer (layer_2) in the Name column of the Input table. The chosen

layer name will now be displayed in the Selected Layer(s) panel under the Layer Properties tab.

The right panel of the Layer Properties tab lists the available Layer Based Models (see Figure

3.11).


17

Figure 3.11: Choosing the Layer Based Model

3. Select the Salt Movement check box. The Salt editor window will open. It displays Age and

Thickness columns for three layers and three graphical input panels, one for each layer (see

Figure 3.12). Since only one layer (layer_2) in the 1D Input has been determined for salt

movement, only the Age and the Thickness columns for that layer contain default data.

4. There are two ways to set up salt thickness through time:

a) by entering numerical values directly into the table or

b) by drawing the changes directly into the graph. Click in the graphic panel. The cursor will

turn into a cross hair. Click on the trend, a node (small black square) will appear. Drag the

node to any desired place (to drag, hold the left mouse button and move the cursor) and

drop it with another click.

Note To delete a node, click it with the middle mouse button.

Either way, follow Figure 3.12 to enter age and thickness data into the columns for layer_2.

Note It is not possible to enter any property (such as Thickness) for a layer prior to its deposition. Therefore, in this example, salt movement can only begin after deposition of layer_2, i.e. after 40 Ma.

Figure 3.12: The Salt editor


18

5. Click OK to apply the modifications and close the Salt editor window.

Note The salt layer (layer_2) in the Input table will now show a light green background color. The color indicates that salt movement has been assigned to that layer. When you click in the cell of layer_2 in the table on the left, you will see that the small square next to Salt Movement in the lower right window is checked (see Figure 3.13).

Figure 3.13: Changes to the Input panel after entering salt movement

6. Save your model.

7. In the upper right panel of the PetroMod 1D Input window, click the Input Burial History tab. The

graphic for the Input Burial History will be displayed (see Figure 3.14). The thickness of the salt

layer (layer_2) varies over time.

Important When you select this tab for the first time, it may take a few seconds until the calculation has completed and the geometry can be displayed. What you see, is not yet the result of a simulation. This input burial history is a mere graphic representation of the built geometry and does not take compaction into account. The Input Burial History diagram allows you to check the geometry evolution of your model prior to simulation.

Figure 3.14: The Input Burial History diagram displaying the salt movement.


19

8. In order to proceed with the tutorial version that is valid for PetroMod 1D and 1D Express, we

need to take off the data for the salt movement again. To do this, click in the cell of layer_2 in the

Input table on the left and deselect the Salt Movement check box in the lower right window (see

Figure 3.13).

9. Save your model again.

3.4.6 Input Burial History Diagram

The main 1D model input data have been entered. You can now check visually the geometry evolution

of your model through the Input Burial History tab. When you click this tab for the first time, it may take

a few seconds until the calculation has completed and the geometry can be displayed. What you see

is not yet the result of a simulation. This input burial history is a mere graphic representation of the

built geometry and does not take compaction into account. The Input Burial History diagram allows

you to check the geometry evolution of your model prior to simulation.

1. In the upper right panel of the PetroMod 1D Input tab, click the Input Burial History tab. The input

burial history will be displayed in a diagram (see Figure 3.15).

2. Check the geometry evolution of your model prior to simulation.

Figure 3.15: The Input Burial History tab for verification of your input data

Before running the simulation, boundary conditions (e.g. heat flow) need to be set. Please proceed to

“Exercise 2. Setting Boundary Conditions”.


20


21

4 Exercise 2 Setting Boundary Conditions

In this exercise we will set boundary conditions for our model – basal heat flow (HF), paleo water

depth (PWD), and sediment water interface temperature (SWIT). The boundary conditions define the

basic energetic conditions for the temperature and burial depth of the source rock and, consequently,

for the maturation of organic matter through time.

4.1 Loading the 1D Model

Load the model you built in Exercise 1. You can simply drag TestWell_1 from the right panel (Project

tab or Base Map tab) to the Input table on the left.

Alternatively,

1. click Open on the File menu. The Open PetroMod Model Directory window will appear. In the

Look in: field you will find the data path to the subdirectory pm1d of your project directory

1D_Project.

2. Click TestWell_1.

3. Click OK.

4.2 Opening the Boundary Assignment Table

Click the Boundary Assignment tab next to the Input tab. The Boundary Assignment tab consists of

an input table on the left side, and three graphics on the right side of the screen: PWD (Paleo Water

Depth), SWIT (Sediment Water Interface Temperature), and HF (Heat Flow). The values can be set

either by manually writing the numerical values into the table or by moving the graph.

Note As long as no user-defined trends have been entered, the Boundary Assignment tab only displays the default trends, i.e a time-invariant PWD, SWIT, and HF of 0 m, 20 centigrades, and 60 mW per m2, respectively.

Important In some cases it is possible that the default age in the first row of the Age columns in the Boundary Assignment table is not set correctly. If this is the case, please correct the value to 60 Ma manually.


22

Figure 4.1: Boundary Assignments – default configuration

4.3 Setting Paleo Water Depth

Changing/Setting the Values Graphically

1. In the Boundary Assignments tab move the cursor over the PWD trend area on the right side. In

the graphics panel the cursor will turn into cross hairs.

2. Click in the graphic panel to activate the display. When it is active, it will have a thicker black

frame.

3. Click on the trend. It will be highlighted in bright yellow. A node (small solid square) will appear

over the trend line. Click the node with the left mouse button and drag it to any desired place (to

drag, hold the left mouse button and move the cursor). The x-y coordinates (age and PWD value)

will be displayed during editing. To delete a node, click it with the middle mouse button.

4. Graphically set a trend (with positive PWD values) more or less similar to Figure 4.3. The values in

the table will be updated automatically.

5. Save the model.

Notes • The age and water depth settings can be modified at any time by either dragging the

nodes to a new position or by entering a new value into the table. As the graphics and the tables are "communicating with each other", each modification in one widget will immediately be updated in the other.

Using the Table to Create a Trend:

All values can be entered directly into the table without using the graphical mode.

1. Enter values according to Figure 4.3. This way you can also modify the age or depth values, which

have been set graphically before.

2. Save the model.


23

4.4 Setting the Sediment Water Interface Temperature

IES offers a special tool to simplify setting the sediment water interface temperature (SWIT). It could

also be done in the same way as the PWD and HF trends. However, this would be quite time

consuming. Additionally, data for SWIT variations over the geologic past are often missing. Therefore,

we will use a tool to calculate and set the SWIT trend automatically. This tool has been integrated in

all PetroMod modules (PetroMod 1D, PetroBuilder 2D and Input 3D).

Setting an Automatically Calculated SWIT Trend:

1. Click the Location Editor for SWI Temperature Calculation button . The Global Mean Surface Temperature window will open. It displays a simplified map of mean sea surface

temperatures over the past 360 million years for both hemispheres according to Wygrala (1989) -

see Figure 4.2.

2. Select the SWI Location On/Off check box to activate the automatic SWIT calculation. Per default,

the dialog box is set to Off.

3. Let us presume that TestWell_1 lies in the Northern German Basin. Select the present-day

hemisphere Northern from the drop-down list, the continental zone Europe, and the latitude 55.

The temperature evolution through time will be reconstructed accordingly taking into account

continental drift and climate change. A black line tracks the movement of the respective location

over time. Important The automatic SWIT temperature assignment provides only a rough approximation to the actual sediment-water interface temperatures. The temperature calculation takes the paleo water depth into account. For this, the paleo water depth (PWD) needs to be set before assigning the SWIT temperature.

Figure 4.2: Global Mean Surface Temperature calculation based on Wygrala (1989)


24

4. Click Save on the File menu of the Global Mean Surface Temperature window. The

corresponding SWI temperatures (corrected for the PWD) will automatically be entered into the

Boundary Assignment table. Temperatures will be shown for all ages for which PWD trend data

have been entered (see Figure 4.3).

5. Save the edits in the PetroMod 1D window.


Although it is more user-friendly to use the tool, you could also create or modify the SWIT trend in the

same way as PWD and HF by either dragging the nodes to a new position or by entering a new value

into the table.

Using the Table to Create a Trend

Just like PWD and HF values, SWIT values can be entered directly into the table without using the

graphic mode. In case of automatic SWIT calculation no values need to be entered manually.

Notes • As the graphics and the tables are "communicating with each other", each

modification in one widget will be updated automatically in the other. • The annotation for the age-axis is only shown above the PWD graph, but is also

valid for the SWIT and HF trends.

4.5 Setting Heat Flow

A heat flow trend (HF) can be set in the same way as the PWD trend.


1. Move the cursor over the HF graphic on the right side. In the graphics panel, the cursor will turn

into cross hairs.

2. Click in the graphic panel to activate the display. When it is active, it will have a thicker black

frame.

3. Click with the left mouse button on the trend line. It will be highlighted in bright yellow. A node

(small solid square) will appear over the trend line. Click the node with the left mouse button and

drag it to any desired place (to drag, hold the left mouse button and move the cursor). The x-y

coordinates (age and HF value) will be displayed during editing. To delete a node, click it with the

middle mouse button.


25

4. Graphically set a trend more or less similar to the graph in Figure 4.3. The values in the table will

be updated automatically.

5. Save the model.

Notes • The age and water depth settings can be modified at any time by either dragging the

nodes to a new position or by entering a new value into the table. As the graphics and the tables are "communicating with each other", each modification in one widget will immediately be updated in the other.

• The annotation for the age-axis is only shown above the PWD graph, but is also valid for the SWIT and HF graphs.

Using the Table to Create a Trend

All values can be entered directly into the table without using the graphical mode.

1. Enter the values according to Figure 4.3. You may also modify the age or depth values, which

have been graphically set before.

2. Save the model.

Figure 4.3: Boundary Assignments with all values entered

You have now completed setting the input parameters and boundary conditions. Your 1D model is

ready for simulation.

5 Exercise 3 Simulation / Default Outputs

In this exercise we will run a simulation. We will then go over a few examples of the default output

panel combinations of PetroMod 1D. Later in the exercise the output panels will be adapted and

modified. PetroMod 1D also offers the user the opportunity to create a new output panel which suits

better his/her needs. We will go over this option in exercise 4. With Petromod 9.0 SP3 we have

launched a new tool, the Default Manager which enables the user to choose which 1D output

templates should appear per default in the Output panel. For more information please refer to the

Quick Reference Guide of the Default Manager.

5.1 Simulation

The simulation will start automatically, when the Output tab in PetroMod 1D is opened for the first

time. No specific simulator options need to be set. The settings in the Input table (e.g. age, lithologies,

kinetics, salt movement, etc.) are automatically considered for the simulation.

1. Click the Output tab. The simulation will be performed automatically. Depending on the speed of

your computer, this may take only a very short time. A progress report can be followed in the lower

left part of the PetroMod 1D window (see Figure 5.1).

Figure 5.1: Progress report during simulation

2. To enlarge the display of the output panels as much as possible, click the Control Panel and

the Report buttons. The Output Control panel and the simulation report panel at the bottom of


27

the PetroMod 1D Output window will disappear. The Output Control Panel can only be displayed

along with the simulation report panel. Click both the Control Panel and the Report buttons to

display the Output Control Panel again. In the Output Control Panel, you have the options to clear

the diagrams (Clear Panels button), re-run a simulation (Calculate button), and display newly

calculated results in the output templates (Apply button).

After the simulation has ended, the results will be displayed in standard templates. In the Output

window click the respective tab at the bottom of the templates (see Figure 5.2) to open an individual

template.

Figure 5.2: Selection of Output Panel tabs after simulation (the figure split the panel in two parts to fit the manual)

5.2 Examples for the Most Frequently Used Templates

Example A: Temp_Ro_bh (Temperature - Vitrinite Reflectance - Burial History) displays two depth

plots for temperature and vitrinite reflectance on the left, and a burial history plot with a temperature

overlay on the right. Click the Report button to enlarge the graphics.

Figure 5.3: Temp_Ro_bh


28

Example B: Temp_Ro (Temperature-Vitrinite Reflectance) displays two depth plots for temperature

and vitrinite reflectance trends on the left, as well as two time plots for temperature and vitrinite

reflectance on the right (For information on how to adjust the readability of the units see the section

“5.3 Customize the Output Display” in this chapter.)

Figure 5.4: Temp_Ro

Example C: Pressure displays a depth plot for lithostatic, hydrostatic and pore pressure on the left

side, and on the right, the burial history with a porosity overlay.


29

Figure 5.5: Pressure

Further templates can be created and customized. That way any simulation result or combination of

results can be displayed (see also the chapter 6 “Create Additional Templates”). Next, we will

customize the look of the existing output displays.

5.3 Customizing the Default Output Display

PetroMod 1D allows you to modify and customize the visual presentation of the panels. For example,

you will be able to resize panels, individualize colors, or highlight or delete certain parts of the output.

In the following we will go through some examples to demonstrate the possibilities to you. The newly

created output panels will then also appear locally in the Default Manager, a new tool we launched

with Petromod 9.0 SP3. It enables the user to determine the default units, the colors for the overlays,

and which 1D output templates should appear per default in the Output panel. For more information

please refer to the Quick Reference Guide of the Default Manager

5.3.1 How to Resize the Panels

1. Click the Temp_Ro_bh tab to display the Temperature - Vitrinite Reflectance - Burial History

template.

2. Click the splitter between two output panels, e.g. the temperature-depth plot on the upper left side

and the vitrinite reflectance-depth plot (Sweeney & Burnham(1990)) on the lower left side.

3. Move the cursor while holding the left mouse button: Move the splitter(s) so that only the

temperature-depth plot on the left, and the burial history with the temperature overlay on the right

will be displayed, i.e. hide the vitrinite reflectance-depth plot on the lower left side.


30

Figure 5.6: Hiding the Vitrinite Reflectance Depth plot

Note Of course, you can also re-size the entire window to increase the size of the individual diagrams by clicking the lower right corner of the window frame (in Windows, the cursor will turn into a two-headed arrow), hold the left mouse button and move the cursor towards the lower right corner of your screen. The PetroMod 1D window will be re-sized proportionally.

5.3.2 How to Add Values to the Scale in the Burial History Plot

The age scale (top of the burial history plot on the right side of the Temperature - Vitrinite Reflectance

- Burial History template) has expanded due to the resizing of the panel. The values are well readable,

yet there is enough space to show more details, e.g. one value every 10 million years.

1. Double-click on the age scale or one of the values on the age scale. The Units - limits dialog box

will open. This box allows you to specify and edit the characteristics of the chosen axis.

Note The Major Ticks refer to absolute values (e.g. one major tick every 10 million years). Numerical values are displayed at each major tick. The number to be entered for Minor Ticks refers to the number of intervals between two major ticks. The minimum number of minor ticks is therefore 1 (= one interval between two major ticks).

2. Set the value for Major ticks to 10, i.e. one major tick and displayed value every 10 million years,

and for Minor ticks to 5 corresponding to 5 intervals of 2 million years each. Click OK.


31

Figure 5.7: Units–limits dialog box - Age

5.3.3 How to Blend out the Paleo Water Depth

Per default the burial history plot displays paleo water depth (PWD), i.e. the PWD values that we have

set as boundary conditions in the Input table in exercise 2. In the Output, the PWD is displayed as a

white margin at the top of the burial history plot, which - according to the PWD settings - thins and

thickens and finally pinches out in the Neogene (PWD = 0 m at 10 Ma).

1. Click in the burial history plot (right panel). A thick black frame will indicate that the panel is active.

2. To display the burial history plot without paleo water depths, click the Water Depth button .

The white margin will disappear. Compare now the burial history plots in Figures 5.6 and 5.8.

5.3.4 How to Choose a Different Overlay and Change the Units

With Petromod 9.0 SP3 we have launched a new tool, the Default Manager which enables the user to

determine the default units, the colors for the overlays and which 1D output templates should appear

per default in the Output panel. For more information please refer to the Quick Reference Guide of the

Default Manager.

1. Click with the right mouse button in the burial history plot which causes a shortcut menu to open.

2. Click Overlay, point to HC Zones, then click Zone_Tissot_et_al(1988)_T2. The hydrocarbon

zones according to the specified kinetic will be displayed.

3. Click the Source Rock button . The HC Zone overlay will now be displayed for the source rock

only (in our example layer_4 - see Figure 5.8), i.e. for the layer that has the assigned source rock

properties (TOC, HI, kinetics) in the Input tab.


32

Figure 5.8: Burial history with hydrocarbon zone overlay for source rock layer only

Note Generation of liquids ("oil") does not start until about 8 Ma in this model. The major part of the source rock is still immature.

4. Click again the Source Rock button. The HC Zone overlay will be displayed for all layers again.


6. Click Overlay, point to Compaction, then click Pressure: Effective Stress. The calculated

effective stress of your 1D model and its variation over time and depth will be displayed. The

default unit for pressure overlays is the SI (=International System of Units) unit MPa (10^6 Pascals

or Newtons per square meter).


8. Click Overlay Settings. The Overlay settings box will open.

9. In the list click psi (pounds per square inch) to choose as the overlay unit.


33

Figure 5.9: Burial history plot with Pressure: Effective Stress (psi) overlay

10. Click OK. The Overlay settings box will close. The effective stress will now be displayed in psi units and the legend will be updated accordingly.

Note When you move the cursor over the burial history plot, the Cell number, the X and Y coordinates (age and depth, respectively), and the overlay Value (pore pressure in psi units) will be displayed in the lower right corner of the PetroMod1D window. For this functionality, the burial history panel needs to be active (highlighted by a thicker black frame).

5.3.5 How to Use the Value Pointer

1. Click in the burial history plot (right panel). A thick black frame will indicate that the panel is active.

2. Click the Value Pointer button on the toolbar of the PetroMod1D window.

3. Click with the left mouse button anywhere in the burial history plot. A label with the overlay value

(effective stress in psi units) will be displayed at the location where you have clicked.

4. Repeat the labeling for different locations in the burial history plot.

5. To remove the labels, click the Clear Value Pointers button .

6. Now, right-click in the burial history plot which causes a shortcut menu to open.

7. Click Store Overlay in the list. The values for the current overlay have been stored and will be

available even if a different overlay will be chosen.

8. Right-click again in the burial history plot.

9. Click Overlay, point to Temperature, then click Thermal Conductivity: Vertical. The calculated

vertical thermal conductivity for your 1D model and its variation over time and depth will be

displayed. The default unit for thermal conductivity is Wm/K.

10. Click again the Value Pointer button on the toolbar of the PetroMod1D window.


34

11. Click with the left mouse button anywhere in the burial history plot. A label will be displayed at the

location, where you have clicked. It will show overlay values for vertical thermal conductivity (in

W/mK units) and effective stress (in psi units), because we had previously stored that.

Figure 5.10: Burial history with vertical thermal conductivity overlay and value pointers

Note Due to the properties of the chosen salt lithology, the salt layer (layer_2) shows considerably higher vertical thermal conductivities than the other layers.

5.3.6 How to Change the Overlay Colors

With Petromod 9.0 SP3 we have launched a new tool, the Default Manager which enables the user to

determine the default colors of the overlays. For more information please refer to the Quick Reference

Guide of the Default Manager.


2. Click Overlay Settings in the list. The Overlay settings box will open.

3. Click Options…, and then click the Colormap tab in the Options window.

4. Click ies_purpblwhtrd from the drop-down list.

Note The ies_purpblwhtrd map has 64 colors (in contrast to the 20 colors of the Standard color map).

5. In the Color Map panel, set the size of the color map to 64.

6. The visible range for the color distribution in the overlay can also be adapted. Click the Classes

tab, then select the visible range check box and set the max value at 3.5 and select use ranges.

5.3.7 How to Adjust the Scale in the Temperature Depth Plot

The temperature scale at the top of the temperature-depth plot on the left side of the PetroMod 1D

Output window has been "compressed" due to the re-sizing of the panel. The values are not properly

readable.

1. Double-click on the temperature scale or one of the temperature values at the top of the

temperature-depth plot. The Units - limits dialog box will open.

2. Play with the Min and Max values and the Major and Minor Tick values to increase the readability

of the temperature axis scale. Click Apply to see the result of each modification. For instance, set

the Max value to 200 and the Major and Minor Ticks distance to 100 (one tick for every 100

centigrade) and 1 (one interval between two ticks) respectively.

6 Exercise 4 Creating Your Own Output Templates

Advanced users appreciate PetroMod 1D's built-in functionality to create additional templates for the

output of 1D models. This tool allows you to create almost any arrangement of depth and time

diagrams. While the structure and the content of the new template will be defined during the creation

of a template, output features such as colors, grid lines etc. will be conveniently customized in the

Output, i.e. when actual model results will be displayed.

6.1 Creating an Additional Output Template

The following section will give you an overview over how to create templates in PetroMod 1D. You are

free to choose the number and sizes of panels within a template. The default templates (see Exercise

4) may serve as examples of how to set up individual panels.

The size and resolution of your screen are crucial for the proper synoptical display of the diagrams

within a template. The size and proportion of individual panels can later be changed in the Output

window simply by moving panel borders with the left mouse button.

In case you have closed the PetroMod 1D Output,

1. Open PetroMod 1D

2. Load your model, i.e. TestWell_1

3. Click the Output tab, click Clear Panels in the Output Control Panel and re-run the simulation

by clicking Calculate. Then click Apply to display the output panels.

4. To create a new template, click the Template Wizard button. The Output Template Wizard

window will open (see Figure 6.1).

5. Type a name for the new template, in our example MyNewTemplate into the Name field.

6. Press Enter (NOT OK!) to confirm the entered new name. An undefined main panel will be

displayed and the name MyNewTemplate will appear in the lower left panel of the wizard.


42

Figure 6.1: The Output Template Wizard window

7. Click the Add Vertical Splitter button in the right top corner of the Output Template Wizard

window.

8. Click in the dimmed panel to subdivide it into individual compartments (panels) according to

Figure 6.2. If necessary, you can click the Undo last split action button to undo a

separation.

9. Proceed in the same way for the horizontal splitter , which can also be found in the right top

corner of the Output Template Wizard window. This will determine the general look of the

template. If necessary, you can click the Undo last split action button to undo a separation.

Notes • The size and proportion of the individual panels can later be fine-tuned in the Output

window by moving the panel borders with the left mouse button. • As soon as you have created more than one panel in the Output Template Wizard

window, the active panel, i.e. the panel, to which properties can be assigned, appears dimmed, while the others remain white. In Figure 6.2, the left panel is active.

Figure 6.15: The new template

Note Overlays that need to be calculated during simulation such as Hydrocarbon Zones, Petroleum Generation Potential, and Calibration can only be added after simulation took place.

Important When you create a new template to display your data while being in the Output window (i.e. after simulation), you may need to close the application and reopen PetroMod 1D to allow an update on the new template. Otherwise, the panels/results may not be displayed in the new template.

6.2 Customizing the New Template in the Output Tab

While structure and content of the new template are defined during the creation of a template in the

Output Template Wizard, it is useful to customize the display for the individual panels in the Output

tab, when you are able to see the actual results of your model. PetroMod 1D provides a range of built-

in functions to customize diagrams. Some of them (e.g. to change the axis scaling) have already been

introduced for depth and burial history plots in exercise 4.

How to Customize the Time Plot

1. Click in the upper right diagram displaying the evolution of the transformation ratio with time. A

thick black frame will indicate that the panel is active. Layer_1 is displayed by default, you can

see that by the blue fill in the bottom cell of a vertical stack of cells at the right margin of the panel.

However, the transformation ratio is only meaningful for layers, which contain organic carbon (i.e.


52

source rock layers). Layer_1 is not the source rock layer. In our model layer_4 was specified as

the source rock layer.

2. Move the cursor, which has turned to cross-hairs over the right margin of the panel. A column with

the vertical stack of cells is displayed at this margin. Each cell conceals a layer label. When you

move over the stack, the label of each cell will be displayed.

3. Move the cursor over the 4th cell from below (see Figure 6.16).

4. Click in that cell. The transformation ratio curve will be displayed for layer_4, the label will change

accordingly.

Note The calculated transformation ratio is much lower for your source rock (layer_4) than that for layer_1. This is simply due to the fact that layer_4 has not subsided as much as layer_1, which is the bottom layer in your model. Layer_4 has therefore encountered lower pressure and temperature conditions than layer_1. The calculated transformation ratio of the organic matter is hence lower. For layer_1, which according to your input does not contain organic matter, the calculated higher transformation ratio is purely theoretical.

Figure 6.16: Customizing the Transformation Ratio Diagram (1)

5. Double-click on the vertical scale or one of the numbers on the right scale of the transformation

ratio diagram. The Units - limits dialog box will open.

6. Type 0.33 for the Max value to be displayed.

7. Click OK to confirm the modification and close the Units - limits dialog box.


53

Figure 6.17: Customizing the Transformation Ratio diagram (2)

8. Now double-click on the horizontal scale or one of the values on the top of the Transformation

Ratio diagram. The Units - limits dialog box will open.

9. Type 18 for the Max value to be displayed, set the Major Ticks to 5 and the Minor Ticks to 5.

10. Click OK to confirm the modification and close the Units - limits dialog box. The time scale of the

transformation ratio curve will now be concentrated on the main period of petroleum generation

(compare Figures 6.16-6.18).

Figure 6.18: Customizing the Transformation Ratio diagram (3)

11. Make sure that the curve in the Transformation Ratio diagram is active. This will be indicated by

appearing in yellow.


54

12. Click with the right mouse button in the Transformation Ratio diagram. A shortcut menu will open.

13. Click Curve Properties. Here the line width, shape and color, can be chosen (see Figure 6.19).

14. Determine the desired width, shape and color of the line and click the Select button at the bottom

of the box to confirm your selection.

Figure 6.19: Setting the curve properties

15. Click the Update Current Template button on the toolbar of the PetroMod 1D window to

update the displayed template. The modifications you have applied to the design of the diagrams

will be stored for the current session. You will be asked, whether you wish to save the template

update. Click Yes. The changes will now be saved for MyNewTemplate. This means that the

update of the MyNewTemplate template is now permanent.

16. Move now to a different template, e.g. the Temperature-Vitrinite Reflectance template, by clicking

the Temp_Ro tab at the bottom of the output panels. The Temperature-Vitrinite Reflectance

template will be displayed.

17. Go back to your newly created template, by clicking the MyNewTemplate tab at the bottom of the

output panels. The template you have created will be displayed again. In the upper right panel, the

Transformation Ratio evolution will be directly displayed for layer_4. Due to the update, no further

modifications of the display are needed.

7 Exercise 5 Using PetroWells to Implement Calibration Data

PetroWells is part of the PetroMod Editors family. It is the tool to generate and edit wells for any given

project (chosen from the PetroMod Command Menu or from within one of the PetroMod modules). It is

included for free in this software package. Calibration data are essential for the verification of

geological models. Here, you can implement actual empirical data for calibration by creating and

editing wells. The well data of an individual project can then be accessed from all PetroMod

applications and are thus available to each individual module within the same project. Well calibration

data inserted into this 1D or 1D Express model can later be accessed from all other PetroMod

applications.

7.1 Creating Wells in PetroWells

To open PetroWells from within the PetroMod 1D module, click the Calibration Data Editor button

. The PetroWells window will open (see Figure 7.1).

Figure 7.1: The PetroWells window


57

The PetroWells window allows you to import, generate, and manage individual calibration wells and

well lists, i.e. groups of wells. The left panel of the window displays ALL wells of the current project.

The right panel allows you to view the well. Only wells that are read into a Well List can be edited.

7.1.1 How to Create a Well List

1. Click Wells in the tree. The Wells box will open

Figure 7.2: The Wells box

2. Enter a name for the well list, in our example enter Group1, in the top line of the window and click

the New Well List button.

3. Both windows will be updated with the newly created well list.

The wells belonging to a specific well list or group are displayed in the tree. In this exercise, you will

create three wells belonging to Group1.

7.1.2 How to Create wells

1. Make sure that well list Group1 is higlighted in the tree.

Figure 7.3: The PetroWells group window


58

2. In the Group1 box, click Edit. The Wells in List table will open.

3. Fill in the columns for Well Names, Common Names if you like, Well Symbol Color, X-Y World

coordinates, etc. according to Figure 7.4. All PetroMod tables contain cells for manual input and

cells which offer an input selection. Double-click in the latter (e.g. Well Symbol Color and World

Coordinate Unit columns) and make your selection.

Figure 7.4: The Well Data table

Notes • The UWI (unique well identifier) will be assigned automatically to the well. For each

well a different UWI will be assigned. • In the Symbol list of the Symbol column (12), you can select either a Marker (e.g.

Asterisk, Circle, Plus, etc.) or a Wellsymbol (e.g. Abandoned, Gas w/ oil show, Dry hole).

• The TDV (Time/Depth Velocity) allows the integration of special time/depth conversion models.

• Click i for a list of different abbreviations.

4. Click the Apply button (green check mark) in the Wells in List window to confirm your settings.

5. Click Close on the File menu to close the Wells in List window. The ALL list as well as the Group1

list will be updated with the three new wells.

6. Click the Save button to save the newly created wells.

7.1.3 How to Enter Calibration Data

In this exercise, we will enter empirical data for vitrinite reflectance and temperature into CalibWell1.

The data will later be used in the next exercise for the calibration of our model calibration.

1. If you closed PetroWells click the Calibration Data Editor button in PetroMod 1D to reopen

it.

2. Click Group1 in the tree in the PetroWells window.

8 Exercise 6 Calibration

Certain templates contain depth plots of calculated trends. These trends can be compared to

calibration data. The calibration is necessary to adapt the model to observations in the field. In

“Exercise 5. Using PetroWells to Insert Calibration Data” empirical data for vitrinite reflectance, and

temperature have been entered into CalibWell1 using PetroWells. We will now use these data in

PetroMod 1D for calibration. The calibration data can be plotted in individual panels alongside the

output of our model TestWell_1. A synoptical view of modeled data and calibration data allows you to

adapt the model input. For instance, heat flow (Boundary Assignment tab) can be modified, so that the

simulation results of the adapted model fit the calibration data.

8.1 Loading Calibration Data Directly into One Output Panel

1. Load the model TestWell_1 in PetroMod 1D. Click the Output tab.

2. Choose a template that displays depth plots of temperature and/or vitrinite reflectance, e.g. the

default template Temp_Ro.

3. Click in the Temperature or the Vitrinite Reflectance (Sweeney&Burnham(1990)_EASY%Ro)

panel. A thick black frame will indicate that the panel is active.

4. Click with the right mouse button in the panel which causes a shortcut menu to open.

5. Click Calibration Data... Alternatively, you can also click the Add Calibration Data button

on the toolbar of the PetroMod 1D window. In either case, the Well Selection window will appear

(see Figure 8.1). The Well Selection window pulls data from PetroWells and displays all of the

wells within a well list.

6. Click Group1 in the Well Lists drop-down list. The wells belonging to Group1 will be displayed.


65

Figure 8.1: Well Selection window

7. Click CalibWell1 on the list.

8. Click OK to display the calibration data of CalibWell1 and close the Well Selection window. The

comparison data will now be displayed with the settings you have previously chosen in PetroWells

(in this case: size = 10 for the calibration data symbols; blue solid triangles for temperature; red

solid circles for vitrinite reflectance - see Figure 8.2).

Figure 8.2: Comparison of model data with calibration data prior to calibration


66

The temperature and vitrinite reflectance calibration data fit the model results reasonably well.

However, we will calibrate the model data to create a closer match between real empirical and model

data. Before we continue, we will practice an alternative way to load the calibration data. We need to

first clear the calibration data from the displays again.

How To Remove Calibration Data from the Display

1. Click the calibration value in the panel or the annotation at the bottom of the panel, in our example

CalibWell1. The annotation font will change to bold, the symbols in the panel will be highlighted in

yellow (hardly visible).

2. Right-click the symbol or the annotation. A shortcut menu will appear.

3. Click Delete to delete the calibration data. The selected calibration values and the annotation will

disappear.

8.2 Loading All Calibration Data at Once

There is an alternative way to load calibration data, which is recommended, when calibration data are

available for many different parameters (temperature, vitrinite reflectance, etc.). The advantage: once

loaded, the calibration data will automatically be displayed for each parameter in the output.

1. Click the Input tab in the PetroMod 1D window. Make sure that your model TestWell_1 has been

loaded.

2. Click the Auto. Calibration Data tab in the lower right panel of the PetroMod 1D Input window.

This tab lists the well groups and wells in a panel on the left (see Figure 8.3).

Figure 8.3: Automatic loading of all calibration data

3. Expand Group1, in case it is not yet expanded. Group1 contains two wells. CalibWell1, and

CalibWell3. We deleted CalibWell 2 in exercise 7.2.

4. Click CalibWell1, hold the left mouse button, drag it over to the right, and drop it into the

Assigned to Model: [TestWell_1] panel. The well name CalibWell1 will appear in the right panel.


67

All calibration data related to CalibWell1 will now automatically be loaded into your model

TestWell_1.

Note To unload the calibration data again, right-click the well name in the Assigned to Model: [TestWell_1] panel and click Delete on the shortcut menu.

5. Click the PetroMod 1D Output tab. The PetroMod 1D Output window will be displayed. Click the

Temperature/Depth panel (Temp_Ro). If you followed this tutorial so far, only the graphs for

temperature and vitrinite reflectance should be displayed, but no calibration values since we

removed them at the end of exercise 8.1, "How To Remove Calibration Data from the Display".

6. In the Output Control panel, click the Clear panels button to empty all panels.

Note There is no need for another simulation, so we will not click the Calculate button.

7. Then click the Apply button. The diagrams will be displayed again, but this time along with the

calibration values for temperature and vitrinite reflectance that you have loaded from CalibWell1.

8. Click the Temp_Ro tab to display the model template along with the calibration data.

8.3 Calibrating the Model Data

When you click the Temp_Ro tab to compare the model with the calibration values, you can see that

the temperature data of our calibration well and of TestWell_1 show some discrepancies. We will now

calibrate TestWell_1 against the calibration data to find a better fit and thus adapt the model to the

situation in the field.

1. When you look at the Temperature/Depth plot you will notice that the calibration values for the

temperature are lower than those in our test well. Click the Boundary Assignment tab. The

values for the Heat Flow are in the right column of the table.

2. You can either change the values by manually adjusting the graph on the right or by changing the

values in the table. Set the values according to Figure 8.4. When you change the values in the

table you will notice that the graph on the right will change accordingly.

Figure 8.4: Adjusting the heat flow data for calibration.


68

3. Click again the Output tab to display .

4. Click Clear Panels in the Output Control Panel at the bottom right.

5. Click Calculate. The simulator will run through a new calculation. You can follow the progress in

the report window at the bottom left. The calculation will be finished when Calculated appears in

the Status column in the Output Control Panel.

6. Click Apply. The Output panels will be updated with the new calculations.

7. Click in the Temperature panel in the Temp_Ro tab. A thick black frame will indicate that the

panel is active.

8. Click with the right mouse button in the panel which causes a shortcut menu to open.

9. Click Calibration Data... on this menu. Alternatively, you can also click the Add Calibration Data

button on the toolbar of the PetroMod 1D window. In either case, the Well Selection window

will appear (see Figure 8.1). The Well Selection window pulls data from PetroWells and displays

all of the wells within a well list.

10. Click Group1 in the Well Lists drop-down list. The wells belonging to Group1 will be displayed.

11. Click CalibWell1 on the list.

12. Click OK to display the calibration data related to CalibWell1 and close the Well Selection

window. You will notice immediately that the model matches the calibration data much better than

before (compare Figures 8.2 and 8.5).

Figure 8.5: Comparison of model data with calibration data after calibration


69

13. Save your model. Click Exit on the File menu to exit PetroMod 1D or 1D Express.

Congratulations! This is the end of the tutorial. You have now completed our step-by-step procedure

through the main functions of PetroMod 1D or 1D Express. You have created your own model from

scratch, set up boundary conditions, performed a simulation, built your own template, created

calibration wells in PetroWells and calibrated your model data against the empirical data. You should

now have a better understanding of the software’s functions and application. Please refer for further

and detailed information on the program to the User Manual.
