Region Calculator (RegCalc)

Overview

Purpose

RegCalc is a VIP post-processing application. It is a powerful analysistool which lets you generate region reports for areas not initially

defined as IREGIONs. You can obtain reports for selected timesteps based on the frequency of the WMAP card which is defined in the

simulation file. The region reports in RegCalc contain the followinginformation:

• Pressure weighted by Total and HC Pore Volume

• Fluids-In-Place

• Average Fluid Saturation

A region can be defined in the following ways:

• Define IREGION and XREG cards in the initialization file.

• Define the I, J, K range for the selected grid within the Region

Calculator.

• Import an ASCII file (*.xreg) which contains information about

the XREG. This option could be used when the XREGions areknown but were not defined in the initialization file.

Region definitions can be saved in an ASCII file for repeated use.Region Reports can be saved in a tab-delimited format compatible withmany spreadsheet applications. Region Reports can also be printed.

RegCalc is a convenient tool to retrieve information easily and quickly

for different areas in the reservoir. For example, regions near an aquifer boundary can be defined in order to check pressure and saturations forthe boundary area throughout simulation.

As another example, in the following illustration the grid is clipped in3DView to show only the root grid. Then RegCalc is used to view the

fluids-in-place for the root grid.

R2003.4 Access RegCalc 5

Access RegCalc

Select the RegCalc option on the DESKTOP-VIP Output menu. The

RegCalc Region Definition window opens.

RegCalc User Interface

The RegCalc application consists of two main windows, the RegionDefinition Window and the Region Report window.

The Region Definition window loads the root grid and lets you definethe I, J, K regions and timesteps for calculation. Once defined, regions

can be saved to a Region Definition file.

Procedures are described on the following pages for selecting a VDB orRegion Definition file, defining the calculation regions, and creating

the Region Definition file, if you choose to save the information.

Once you click the Calculate button on the Region

Definition window, the Region Report window opens.

The Region Report window displays the calculations for the regions

you defined within RegCalc and any IREGIONS defined in the

I grid cell range J grid cell range K grid cell range

Open VDB

Open Study

The current Study should open by default when you open RegCalc.Perform the following steps to open a different Study.

1. Open File Selection dialog box. Select the Open Study option onthe Region Calculator File menu, or click the icon on the

toolbar. The File Selection dialog box opens. The Files of Type menu defaults to the .vdb extension, but can be set to list all files.

2. Select Study. Filter to the directory and highlight the file to select.Click the Open button to select it. If the selected Study contains

only one Case, the grid data loads to the Region Calculator. If theselected Study contains multiple Cases, the Case List for theselected Study opens as described below.

Open Case

Perform the following steps to open a Case.

1. Open Case List. Again, when you select a Study with multiplecases, the Case List will open automatically. If you want to change

Cases, select the Open Case option on the Region Calculator Filemenu. The Case List opens as shown below.

2. Select Case. Highlight the Case Name to select in the Case Listand click the OK button. The grid data for the selected Case loadsto the Region Calculator. Note that IREGION definitions do not

Viewing Multiple Cases within the Study

You can open multiple cases for a single study. As you select new cases,only the latest will display in the region calculator. But multiple Region

Report windows will remain open.

R2003.4 Define Regions for Calculation 11

Define Regions for Calculation

Once the grid is open, define any number of gridcell regions for

separate calculations as shown in the illustration below.

Perform the following steps to define the regions.

1. Open New Region dialog box. Select the New Region option on theEdit menu. The New Region dialog box opens as shown below.

The default grid is the ROOT grid. The I, J, and K ranges for theROOT grid display in the entry fields.

2. Select LGR grid (optional). If you want to define a region of anLGR grid, click the Grid menu and select the LGR name from the

list as shown below.

The I, J, and K, ranges for the selected LGR grid displays in the

entry fields.

3. Specify I, J, K gridblock range. Click the stepper buttons beside

each range field to increase (up arrow) or decrease (down arrow)the minimum and maximum value. Or double-click in the entryfield and enter the value.

Click the OK button located at the bottom of the New Region dialog box.

The dialog box closes. The gridblock range of the region you defined

displays in the Region Calculator as shown below.

4. Delete Region if necessary. Click anywhere on the line and selectthe Delete Region option on the Edit menu to delete a region. The

region is removed from the list.

Repeat the above procedures until all the regions are defined. Notice

that the number in the Region column increments for each new regionyou define. This number corresponds to the Region tabs in the RegionReport window.

5. Specify timestep(s). Select the Time in Days option on the Datamenu. The Time in Days list opens as shown below.
