One- and two-dimensional gas reservoir simulators were combined in such a manner that pressure distributions, both in an induced vertical fracture and in the surrounding formation, could be determined as a function of time for any specified well production rate. Basic assumptions regarding the fracture were as follows: (1) the fracture completely penetrates the formation, (2) all flow into the wellbore enters via the fracture, and (3) flow in the fracture is described by darcy's law. The combination model developed provides the only known means of simulating a vertical fracture of given characteristics in a gas reservoir under transient conditions. Thus, the technique developed would be useful in locating wells in a storage field in that the effects of both fracture length and conductivity could be considered prior to drilling and fracturing operations.
