Question: Assuming that kpw = 2000 md - ft, k = 1 md.x, = 1000 ft, = 0.328 ft, calculate the equivalent skin effect and the folds of well productivity increase (at steady state flow) for a reservoir with drainage radius, re = 1490 ft (160 acres) and no wellbore damage. What would be the folds of increase for the same fracture lengths and k w if k = 0.1 md and k = 10 md? Summary of the results: k (md) FCD SH 0.1 1 10 Plot the following: a. Fc Vs. b. Si vs. k c.
