volume weighted average reservoir pressures match the pressures reported in
Chapter 20. Note: the pore volume weighted average reservoir pressure P av is
given by

p -

where N is the total number of gridblocks in the model grid, P, is the oil phase
pressure in gridblock/, and V pj is the pore volume of gridblock/. Chapter 24. 1 0
contains details on how to set up an analytic aquifer. For an example of a data
set with an analytic aquifer model, see data file EXAM9.DAT.

Exercise 21.4 Data set CS-VC.DAT is a vertical column model of the case study.
Sketch the grid to scale, locate the contacts on the sketch, and match reservoir
pressure.

Exercise 21.5 Repeat Exercise 2 1 .4 beginning with the cross-section model data
set CS-XS.DAT.
