Question

Assuming you have two wells producing at steady state in a circular drainage area of re=600 ft, and they are separated by a distance of 70 ft, radius of both wells are rw=0.3 ft, a. Calcuate the productivity index ratio of a single well to two wells system in this circular drainage area b. If both wells are producing at a rate of 120 bbl/d, the viscosity of the oil is 1.2 cp and the permeability is 50 md, calculate total pressure drop to be observed in well#2.

Answer 1

now PIR = 0.107 cfd/psf
