In this example, the well is vertical and we keep the Darcy model. Click on the ‘parameters’
icon and enter the following:
Reservoir parameters:
 Reservoir permeability, k: 25 md.
 Average pressure, Pavg: 5000 psia.
 Well radius, rw: 2.875 in.
 Skin model: check Calculate damage skin from completion.
 Completion model: select Cased hole in the drop list.
 Keep all other parameters at their default values.
Fig. D01.2 • Reservoir parameters
To enter the Cased Hole parameters, use
 Perforation shot density: 4 spf.
 Perforated interval: 23 ft.
 Compacted zone perm: click on and enter kc/k reservoir: 0.4.
 Compacted zone turbulent coef: click on to compute it from kc.
 Keep all other parameters at their default values.
