Relative Permeability Matching

This functionality is available only when relative permeability is specified using Corey correlations. The screen form contains 4 areas.

Area 1.

Contains the following elements:

• – back. To return to the reservoir model;
• Tanks / Wells – tanks and wells are available for matching;
• Name of the selected model in the model tree;
• Objective function. Drop-down list for selecting the function. The following functions are available: water fraction, gas fraction, water and gas fraction;
• Match. To start matching;
• Apply. To apply the parameters obtained during matching. Active after matching is completed.

Area 2.

The table contains the following parameters:

• check box to select a reservoir or well for matching;
• reservoir or well name. By default, all reservoirs or wells in the selected model are displayed;
• Initial residual;
• Final residual.

Area 3.

The table contains the following parameters:

• check box to select a parameter for matching;
• parameter for matching. All available relative permeability parameters are displayed;
• Value. Displays the parameter value from the Relative permeability tab;
• Minimum. Minimum value for matching; matching is not performed below this value;
• Maximum. Maximum value for matching; matching is not performed above this value;
• Calculated value. The value obtained during matching.

Area 4.

Relative permeability plots.

The following elements are available on the plot:

• – Settings. To change the axis parameters. For water, the Y axis options are water fraction and water cut; the X axis options are saturation and date. By default, water fraction and saturation are selected. For gas, the Y axis options are gas fraction and gas oil ratio; the X axis options are saturation and date. By default, gas fraction and saturation are selected;
• Legend in the bottom part of the pane. By default, actual, calculation, and matching are always displayed. Click any of the parameters to hide it on the plot;
• Reset. To reset the plot zoom. If required, you can zoom the plot by selecting the required area with the right mouse button.
