The Wellbore Storage Coefficient can be evaluated using Wellbore Storage plot i.e., pressure vs cumulative water injection plot.

1. On the Wellbore Storage plot, by default the Wellbore Storage analysis line will exist. The Wellbore Storage line will regress on the first 5% of the injection data to evaluate the slope of the line and the Wellbore Storage coefficient.

2. User can change the default data selection by using the data selection tool from the plot toolbar.

3. The Wellbore Storage line can be deleted and can be re-instated using the Lines dialog box.
