As a starting point, let us further assume that the gas PVT has constant viscosity and
compressibility, and that the permeability is homogeneous, with a conventional value k=30
mD.
The reservoir is produced at constant well pressure P=250 psia for ten years. As can be seen
from figures 3 and 4, the match between the analytical model and the numerical model is
excellent, both for early-time transient analysis and long-term forecasting.
