Seismic Volume Rendering & Geobody Extraction

Quickly visualize and detect anomalies in your seismic data and directly input the extracted objects into

your 3D model for enhanced facies classification.

Petrel Seismic Volume Rendering & Geobody Extraction

Visualization and extraction of 3D objects from seismic is critical for improving reservoir understanding,

detecting anomalies, and defining facies. Petrel software now allows users to interactively blend multiple

seismic volumes, isolate areas of interest, and then instantly extract what is visualized into a 3D object

called a geobody. In essence, "what you see is what you pick," making this approach to volume

interpretation fast, intuitive, and accurate. After the geobody has been extracted, it can to be directly

included in the 3D geological model, providing an efficient workflow from seismic to geological modeling.

Benefits

� Interactive volume rendering of regional 3D volumes

� Rapid identification and isolation of areas of interest

� Blend up to 3 volumes for improved interactive reservoir characterization

� RGB blending available

Blending multiple attribute cubes

� WYSIWYG—extraction of geobodies based on visualized results


9

� Inclusion or exclusion of extracted geobody in future settings to allow improved facies detection

� Single-click import into geological model

Extracted geobody imported directly into geological model

� Petrophysical model conditioning with geobody in the geological model


10

Blending amplitude with zone information

� Can be used as hard data in multipoint geostatistics workflow

Seismic volume rendering

Interactively apply transparency on regional 3D seismic volumes to rapidly identify areas of interest. The

ability to set free volumes independent of inline x-lines and time slices and the option to set volumes on

or between horizons allow you to take a more geological approach to visualization. Multiple attribute

cubes can be applied and combined in a number of ways to help further classify the reservoir.

Geobody Extraction

After you have visualized the 3D object, a series of tools allows you to further isolate the body and then

interactively extract it. Once extracted, volumetrics can be calculated or the body can be directly sampled

into a geological model as a discrete object to condition the petrophysical modeling. Existing geobodies

can be included or excluded from further volume extraction for improved classification of facies. The

resulting property can then be used in much the same way as a facies model to condition petrophysical

property models. By filtering on this property, operations such as data analysis, property modeling, and

volume calculations can be performed on the grid cells within the bodies.


11

Seismic Attribute Analysis

A fully integrated solution for seismic attribute extraction and analysis. Choose from an extensive library

of seismic attributes, which can be processed on-the-fly or as background tasks. Capture share and

repeat workflows across projects and fields for improved knowledge management.

Petrel Seismic Attribute Analysis

The attribute generation process contains a library of different single and multi-trace seismic attributes for

display and use within the seismic interpretation workflow. Seismic attribute analysis helps to enhance

information that might be subtle in traditional seismic, leading to a better interpretation of the data.

Multiprocessor capability for rapid attribute calculations

Take advantage of multiprocessor desktop workstations to run attributes faster and in the background,

freeing up the machine and allowing the user to be more productive. Optionally, generate attributes

remotely on a Linux cluster and instantly review and use the results back in Petrel, reducing the time

taken from hours to minutes and allowing more informed decisions to be made quicker.

Genetic Inversion

Seismic reflection data is the primary input for resolving structural and stratigraphic variations between

points of well control in the majority of the world's sedimentary basins for the exploitation of hydrocarbon

resources. Petrel brings a step change to this process with the fully integrated genetic inversion algorithm

allowing geophysicists and geologists to more accurately predict inter well properties from seismic inside

of Petrel. Horizon autotracking options allow you to pick directly on the impedance volume or it can be

used as an input in the enhanced geobody isolation and extraction process for improved reservoir

characterization.

Surface attribute library for rapid prospect identification

A new attribute library gives the user access to over 40 attributes that can be instantly calculated directly

at interpreted events, on nearby uninterpreted events, or between events. This allows the interpreter to

extract the maximum value from seismic data by providing more detail on the subtle lithological variations

of your reservoir without having to generate new seismic attribute volumes, speeding up the prospect

identification and mapping workflows.


12

Iso-frequency attribute in slices

Capture and repeat attributes to share knowledge

Attribute calculations can be built into the Workflow Manager and repeated across different events or

fields to share knowledge between teams and capture parameters for best practices.

Benefits

� Structural attributes can help accelerate the task of picking horizons and faults.

� Seismic attributes related directly to log and rock properties in the model can take advantage of the

integrated petrophysical and facies modeling in the Petrel application, thus defining a better model

and reducing uncertainty.

� A wide range of attributes and combinations of different attributes can be used to identify

stratigraphical and structural events.


13

Ant Tracking combined with amplitude to analyze fault structure

increasing understanding, saving time, and enhancing the mapping workflow.


14

Surface attributes integrated with structural model

� Multithreaded and background processing increase performance and speeds up the calculations,

enabling the user to be more productive.

� Remote attribute generation on a Linux cluster reduces the time from hours to minutes and allows

attribute volumes to be shared among multiple users.

Enhancing seismic workflows

A variety of new workflows can be derived using attributes to

� precondition the data for better horizon autotracking

� enhance the fault signature of the data by calculating variance or chaos, or by filtering structural

smoothing with the edge enhancement option

� precondition the data for seismic facies extraction using relative acoustic impedance or the chaos

attribute to isolate salt bodies

� combine attributes and generate users' own attributes using the seismic calculator.

18

Automated Structural Interpretation

Spend your time understanding the trends of fault systems from these automatically extracted fault

surfaces.

Petrel Automated Structural Interpretation

Increase accuracy while reducing your manual fault interpretation task

Understanding the trends of fault surfaces and fluid flow properties across fault systems is one of the

most important aspects when it comes to reservoir characterization. For many years it has been possible

to spatially interpret horizon reflections but interpretation of fault surfaces or planes has been more

subjective.

The Petrel Automated Structural Interpretation module uses an advanced computing algorithm "Ant

Tracking" to overcome this subjectivity. Now interpreters using 3D seismic data can spend time

understanding the trends of fault surfaces and make correlations from the automatically extracted fault

patches instead of creating fault surfaces individually and manually.

By focusing on structural geology rather than conventional segment picking, Automated Structural

Interpretation reduces conventional interpretation time while increasing your level of geological detail,

structural awareness and reservoir understanding.


19

Interact with the automatically extracted fault patches using a polar plot and various filters to isolate the fault systems interest.

Benefits

� Increases structural accuracy and detail

� Significantly reduces tedious manual interpretation time


20

The Ant Tracking algorithm creates a new fault attribute highlighting fault-surface features

� Provides unbiased, repeatable and highly detailed mapping of discontinuities

� Fully integrates with geological modeling

� Better estimation of complex models

� Optimizes the value of 3D seismic data beyond traditional picking

Automated Structural Interpretation - "Ant Tracking"

Petrel Automated Structural Interpretation - "Ant Tracking"

Depending on your workflow, Automatic Fault extraction can be performed at any scale. During the

exploration phase, the focus may be to look for major tectonic fault systems spanning the basin and

identify their influence on any prospects. Alternatively with known reservoirs, at appraisal, development

or production phase, a similar approach can be applied, but at a local scale. A this scale you are looking

at faults and fault systems that may be the result of tectonic forces from completely different directions

which have affect on ultimate hydrocarbon recovery.

The Ant Tracking workflow consists of four independent steps:

1. Enhance the spatial discontinuities in your seismic data using any edge detection algorithm (i.e.

variance, chaos, edge detection) and optionally, pre-condition your seismic data by reducing noise.

2. Generate the Ant Track Cube and extract the fault patches


21

3. Validate and edit the fault patches

4. Create final fault interpretation model

The first step in the workflow involves the reduction of noise in your seismic data and the creation of an

edge-enhancing attribute (i.e. variance, chaos, dip deviation), highlighting special discontinuities.

During the second step, the Ant Track cube is created. The Ant Tracking algorithm follows an analogy of

ants finding the shortest path between their nest and their food source by communicating using

pheromones, a chemical substance that attracts other ants. The shortest path will be marked with more

pheromones than the longest path and so the next ant is more likely to choose the shortest route, and so

on.

The idea is to distribute a large number of these electronic "ants" in a seismic volume; and let each ant

move along what appears to be a fault surface while emitting "pheromone." Ants deployed along a fault

should be able to trace the fault surface for some distance before being terminated. Surfaces meeting

expectations will be strongly marked by "pheromone." Surfaces unlikely to be faults will be unmarked or

weakly marked. The Ant Tracking algorithm creates a new fault attribute highlighting the corresponding

fault-surface features having orientations within some pre-determined settings. The algorithm then

automatically extracts the result as a set of fault-patches, a highly detailed mapping of discontinuities.

Manual interaction is provided in the third step. The extracted fault patches must be evaluated, edited

and filtered in order to obtain the final interpretation. This is done using an innovative approach applying

an interactive stereo-net and histogram filter tool.

In the final step, the fault patches are used for further seismic interpretation or as input to the fault

modeling directly.


22

Synthetic Seismograms

Bridge the gap between your time and depth domains.

Petrel Synthetic Seismograms

Bridge the gap between your time and depth domains.

Multi-trace synthetic generation lets you fine-tune your seismogram to match the seismic extracted in

wells. The well correlation window helps you to assess the match. Any changes to the time-depth

relationship can be made and seismic horizons can be correlated with the stratigraphic boundaries

identified in your wells. When the time-depth relationship has been fine tuned, all depth indexed well tops

will be automatically assigned the updated time value.

Benefits

� Minimize data load and transfer by using one application where synthetics are integrated with

seismic and well logs.

� Improve your quality control by viewing your synthetic seismogram in a variety of windows including

the 3D, interpretation or well correlation windows.

� Quickly process synthetics using the intuitive Windows guiding and help systems built into Petrel.

� The easy-to-use copy/paste functionality allows you to quickly present your interpretations to

management in any Windows application like Word or PowerPoint.

Features

� Display synthetic seismograms with any other item in Petrel

� Display wells in time

� A "Process diagram dialog" guides you though the steps

� Wavelet extraction from seismic

� Well seismic

Display

The synthetic seismogram can be displayed in the well correlation window, 3D window and interpretation

window.

Wells in time

When a time-depth relationship in wells has been established, wells can be displayed in the time domain

in all 3D and intersection windows.

Process diagram dialog

The Synthetics process dialog leads you through the steps of generating synthetic seismograms from

your well data, and simplifies the display of the data you need to use along the way.

Wavelet extraction from seismic:

Use a collection of traces around the borehole, compute auto-correlation for time window of interest,


23

taper effects etc.

The workflow process for wavelet extraction involves trying several combinations of extraction

parameters, recording the results, and trying different boreholes in order to gain a better understanding of

the nature of the seismic data. The Wavelet Extract option in Petrel gives you the capability of extracting

statistical wavelets from the seismic data at a borehole.

A wavelet can be extracted from some portion of a 3D volume of seismic traces. The statistical extraction

method used in Synthetics assumes that the autocorrelation of the wavelet is the same as the truncated

autocorrelation of the seismic trace. The average autocorrelation from several seismic traces is used to

provide a more representative estimate of the wavelet.

Well seismic

The seismic can be extracted along the well paths and displayed. The extraction is not limited to the

synthetic seismogram generation, but can be done for any type of seismic volume; hence you can display

your seismic attributes in with well logs in the well correlation window.

* To access the synthetic seismograms you need the core module, well correlation and seismic

interpretation module.


24

Domain Conversion

Quickly perform domain conversion backwards and forwards between time and depth. Create your

velocity models directly in Petrel or import from any third party application.

Petrel Domain Conversion

Geophysicists typically work in the time domain while geologists work with depth data. Petrel Domain

Conversion reconciles these differences by helping you make depth data the rule rather than the

exception.

Petrel allows you to quickly perform domain conversion backwards and forwards between time and depth.

All the necessary steps are performed directly in your project, so there is no need to ever leave the

friendly Petrel interface.

Use velocity models to convert between time and depth. Velocity models can now be generated directly in Petrel or imported

from third-party applications

Petrel Domain Conversion involves two simple steps. First you create a velocity model and calibrate it to

the available well markers. Next select the data you wish to domain convert, whether it is surfaces,

horizon and fault interpretations, points, well data, 2D and 3D seismic, or 3D grids.


25

Define the velocity model in a spreadsheet layout where all the data and parameters are selected

Benefits

� Domain conversion runs directly in Petrel, saving you time by avoiding unnecessary input and

output of information.

� Perform domain conversion at any stage in your workflow. Build 3D models in either time or depth,

and convert when it is convenient for you.

� Build multiple velocity models to test different velocity parameter scenarios and obtain a better

understanding of structural uncertainty.

� Use a 3D grid property for depth conversion, useful for conversion of complex structures such as

reversely faulted environments

Features

� Domain conversion of 2D and 3D seismic, surfaces, horizon and fault interpretations, points, wells

and logs, well tops, and 3D grids.


26

Domain conversion is available for 2D and 3D seismic, surfaces, horizon and fault interpretations, points, wells and logs, well

tops, and 3D grids

� Uses a standard layer cake approach for domain conversion, giving you the freedom to select

velocity variations for each layer, while preserving the relationships between faults and horizons.

� Velocity modeling and depth conversion can be run in the Petrel Process Manager, allowing you to

generate a single workflow that spans both time and depth domains.


27

Switch interactively between time and depth

� Supported velocity methods include linear functions V=Vo, V=Vo+kZ, V=Vo+k(Z-Zo). Constants or

surfaces can be used as variables.

� Condition your reservoir model with depth converted seismic attributes sampled into the grid.


29

Seismic Depth Conversion

With a simple click your seismic volume is depth converted according to the velocity functions for the

horizons in a 3D grid. When a seismic volume is depth converted Petrel will locate the time horizons and

the corresponding depth horizon in the two 3D grids and adjust the Z-position of each seismic trace. The

resulting depth converted seismic will be restricted to the boundaries of the 3D depth grid.

The depth converted seismic allows the same options as original seismic, including 3D auto tracking and

manual interpretation. You can display the volume in the interpretation window and create attributes from

the depth data.

Quality Control

� Display the depth converted seismic with property grids or results from simulation to ensure the

quality of the modeling.

� Different disciplines can work together on the same interface.

� Sample depth converted seismic amplitudes or attributes into an existing 3D grid.

Modeled faults and wells displayed with depth converted seismic interpretation

Sampling

Sampling is the process where Petrel investigates the attribute values within a grid cell and populates the

grid cells with one attribute value. The algorithms that can be used in this process are: closest,

interpolate, intersection, and exact.


30

Depth converted seismic is sampled into the 3D grid. The depth converted seismic can be volume rendered

To obtain a realistic and accurate model the sampled seismic attributes can be used to guide or condition

the property modeling.

properties such as porosity

The facies model can be used directly in the petrophysical module

� Guide your algorithms with a range of trends


32

Multipoint Geostatistics

Traditional reservoir modeling techniques use simplified, two-point statistics to represent geological

phenomena that have complex geometrical configurations. The use of multipoint statistics has improved

in recent years, reducing the limitations. The Petrel 2009 release reintroduces multipoint geostatistics,

providing users with new methods to model complex geological features and connectivity. These

workflows work efficiently in multimillion cell models and honor well, seismic, and probability data. The

workflows are much faster than before and use less than five percent of the memory needed to run MPS

in the model, improving performance when using training images.

MPS uses training images to model facies, providing the user with a new method to model complex geological features.

co-kriging with secondary data, excellent for inversion data

� Conditional and unconditional simulation.

Porosity model conditioned to a channel facies

Random Gaussian Simulation

When the correlation between soft data and hard data is zero, the simulation depends on well data only

and is completely independent of sot data such as seismic. As the correlation increases, so does the

dependence of the final result on the seismic data. Petrel software calculates the optimal correlation

between seismic and porosity and uses this as the default for colocated cosimulation. However, this

correlation is one of the sensitivities that should be examined within an uncertainty study. The Petrel

2009 release gives users a quick visual appreciation of the correlation without having to restart the

simulation every time.

Fault Analysis

Calculate fluid flow properties and sealing potential for faults in a Petrel model. Use results directly in

simulation without leaving Petrel.

Petrel Fault Analysis

The Fault Analysis module lets you calculate fluid flow properties and sealing potential for faults in a

Petrel model.

The module uses geologic parameters such as fault displacements and adjacent rock types to estimate

fault zone thickness, permeability and sealing potential. From the fault zone permeability and thickness

estimations, transmissibility multipliers are calculated for each cell that lies adjacent to a fault.

Properties calculated on fault planes

The Fault Analysis module also enables you to assign basic properties to a fault such as a uniform

transmissibility multiplier and threshold pressure. Fault properties can then be visualized in the viewers

and used as keywords in the ECLIPSE simulators.


41

Benefits

� Calculate the sealing potential of faults with user defined equations.

� Generate detailed Allen diagrams for visual analysis.

� Use the calculated transmissibility multiplier directly in simulation without leaving Petrel.

Displacement weighted permeability


42

Fracture Modeling

data in 3D and integrate them seamlessly in the reservoir model. Upscale the fracture properties to the

simulation model and use results directly in simulation.

Petrel Discrete Fracture Modeling

Modeling flow in fractured reservoirs is difficult. The challenge requires a software solution that supports

tight integration between the static and dynamic reservoir modeling disciplines and provides a way to

visualize and analyze many data types that may be direct or indirect indicators of fractures.

Integrated technology for better workflows

Advanced Gridding and Upscaling

Resample and re-grid fine-scale geological models to coarser-scale simulation models using a wide

range of upscaling techniques.

Petrel Advanced Gridding and Upscaling

For resampling fine-scale geological models to scales appropriate for simulation models

Use a wide range of gridding and upscaling techniques

Resample fine-scaled geological models to coarser-scale simulation while still preserving

important details in the geologic model. An assortment of averaging methods includes a flexible

tensor upscaling function for determining effective permeability in each simulation cell.

Advanced gridding techniques include

� Local gridding (LGR) — to create small cells around wells, surface, or polygons for improved

resolution

Local Grid Refinement


48

� Stair step (IJK) gridding — to ensure grid orthogonality when faults are highly inclined

Stair-step faulting

Advantages

� Preserve geologic knowledge scale—construct a simulation grid from the same 3D model as your

fine-scale geological grid

� Get an accurate upscaled representation of your modeled properties—from standard averaging or

flow-based tensor techniques

� Capture complex structural or near-wellbore effects—using advanced gridding techniques

Flow-based tensor upscaling—how it works

When upscaling permeability from a fine geological grid to a coarser simulation grid, a block of grid cells

from the fine grid will have direction-dependant permeability. This is modeled using a permeability tensor.

The default output is permeability properties for X, Y, and Z. You can also request coupling terms XY, XZ,

and YZ. In situations where there are only a few cells in each coarser cell, you can define a skin zone that

includes additional cells outside the coarse cell to calculate the upscaled permeability. The larger zone

improves the pressure field calculations and the accuracy of the flow relative to directional permeability

differences.


49

History Match Analysis

integration with Petrel


50

Identify problem wells

History match analysis—How it works

The tool calculates statistics on the quality of a history match across many realizations and highlights the

best matches for further study. Results are calculated on every well and for every data type (oil rate,

water rate, bhp, water cut, etc.)

By combining different matches into scenarios, you can move from a case view to a field view and down

to the specific details in any well. The results are then displayed in a map window with color codes

indicating good and bad history matches. Instead of looking at hundreds of line plots and trying to find the

best case, the cases are ranked according to your choices.


51

ECLIPSE FrontSim

Rank and screen reservoir models in a dynamic environment by combining ECLIPSE FrontSim

streamline technology with Petrel 3D modeling for more accurate production forecasting.

FrontSim

Rank and screen reservoir models in a dynamic environment by combining industry-standard streamline

technology with intuitive and interactive 3D modeling. ECLIPSE FrontSim streamline reservoir simulation

software is a three-phase, 3D simulator that models multiphase flow of fluids along streamlines. FrontSim

enables you to construct enhanced reservoir models quickly, paving the way for more accurate

production forecasting and better decisions.

The effect of fault seal analysis on streamlines provides additional insight into flow behavior

Benefits

� Efficiently rank, screen and visualize multiple sensitivity runs, combining static and dynamic

information to create more reliable models in less time.

� Optimize well placements by combining streamline analysis with the detailed static model to

enhance sweep efficiency.


52

� Validate upscaled reservoir models with dynamic data by understanding grid orientation issues,

thereby improving the quality of the model used for reservoir simulation.

Streamlines output from FrontSim allow visualization of the fluid movement within your Petrel model

Identify flow patterns

When heterogeneity and reservoir uncertainties are dominating the fluid flow behavior in your reservoir,

stochastic modeling techniques are used to create multiple views of your fine scale geological model.

With FrontSim, you can dynamically identify the tortuous flow paths by visually depicting the

injector-to-producer streamline bundles and make ranking decisions based on production history, not

static methods alone.


53

FrontSim streamlines displayed with Sw cross section and seismic inline

Improve your reservoir management

Identifying optimal drilling locations is not only based on engineering constraints, but also on reservoir

heterogeneity. Running FrontSim on your fine scale geological model lets you identify injectors not

contributing to production, or producers that are cycling injected water. Such analysis lets you make

development and field management decisions to optimize sweep, improve ultimate recovery and

minimize injection costs.


54

Streamline simulation result data

Build better quality models

Identifying the representative model from stochastic analysis is challenging enough. Fine scale

geological models must then be upscaled to reduce the number of cells for practical full-field simulation.

The knowledge gained using FrontSim can directly impact ECLIPSE reservoir simulation models,

resulting in more reliable models with better predictive forecasting.


55

Petrel Drilling Workflows

Well path design, drilling visualization, and real-time model updates

the total cost of your drilling program, using the Petrel Well Cost Optimizer (part of the Well Path Design

module). Targets defined as "must hit" data points for the optimized well paths must can be locked to

platforms, and target-platform sets can be constrained by closed boundaries.


57

Minimize the total cost of a drilling project by evaluating the cost for all possible scenarios

Automatically computed well trajectories are constrained by a user-defined dogleg severity. The output is

a set of optimized trajectories based on geometrical drilling constraints extending from the reservoir back

to the surface. The Drilling Difficulty Index (DDI) provides a first-pass evaluation of the relative difficulty

encountered in drilling a well.

Benefits

� Automatically generate well trajectories and platform locations that minimize the total drilling

Visualize and correlate drilling risks

Geologists and drillers plan better proposals

Drilling events such as lessons learned, best practices, and risks encountered on offset wells (such as

kicks, losses, high/low pressure zones, and other difficult drilling conditions) can be easily imported into

the Petrel application. Geologists can improve well proposals by visualizing and correlating the events on

the 3D and well section windows. Better collaboration while drilling produces more feasible well

proposals.

Visualize drilling events and risks in the Petrel shared earth model using a WITSML view of drilling information

Drillers proactively reduce risk

Risks and events can also be entered directly and edited as needed. They can be migrated to a planned

well, reclassified and correlated to geology. Importing the Osprey Risk drilling risk prediction model

allows a comprehensive view of simulated drilling risks alongside the event-driven drilling knowledge.

The entire operations team makes better decisions


60

Visualizing these risks and events in the overburden shared earth model enables the entire team to

monitor the impact of geology interpretation changes on the drilling process, minimizing geologically

driven risk.

Correlate offset well risks using the well section window

Real-time risk is effectively managed

and other relevant data—from the InterACT real-time monitoring and data delivery application or other

WITSML data sources. Real-time drilling workflows interact closely to update the earth model and well

paths and make critical decisions during the drilling operation.

Real-Time Data Link

The Petrel Real-Time Data Link can connect to streaming real-time data from InterACT wellsite

monitoring and data delivery system. This gives you a secure, real-time data link directly from the wellsite

to the desktop.

Petrel, allowing you to load trajectory and log data. This data is saved with your Petrel project for later

use.

View drilling events in the earth model reduces non-productive time

Now, the Petrel shared earth model can be driven by real-time data, allowing you to understand the full

impact of new geologic knowledge on the well while it is being drilled. Surveillance in a shared earth

model while drilling allows effective cross-discipline collaboration in real time.
