The following information is available from a water drive wet gas reservoir:
pi = 3000 psia
T = 200° F
A = 4500 Acres
uz = 0.016
h = 20 ft.
rw = 0.5ft.
k = 2 md
D = 0.0003 Mcfd`

s=0
fo = 0.94
Pwt = 500 psia
The following table summarize the predicted reservoir pressures based on the
contract (separator gas) rate of 20 MMcfd:

a. Determine if 12 wells are sufficient to meet the contact rate for 3 years.
b. Determine if 12 wells are sufficient to meet the contact rate for 4 years if
they are stimulated such that S = - 3.
