HOMEWORK 9
A multirate pressure drawdown test was run on the discovery well (well #1) in a gas reservoir. The core, well log, and PVT data for well #1 were provided in the earlier homeworks. Given the tests results, reservoir data, and fluid properties determine:
A. k, s, and D
B. a, and b (the deliverability equation coefficients)
Assuming 160-acre spacing and rw = 0.5 ft.
