A mathematical model is presented which forms the basis for a reservoir simulator that can be used to assist in the interpretation and prediction of the performance of hydraulically fractured gas wells completed in noncontinuous sand lense formations. Equations are derived to simulate both reservoir and well performance. They are general in that the following effects are considered: 1) noncontinuous sand lenses, 2) three-dimensional flow in the reservoir and one-dimensional flow in the fracture, 3) non-Darcy flow in the reservoir and fracture, 4) wellbore and fracture storage, 5) formation damage on the fracture face, 6) frictional pressure drop in the production string, and 7) Klinkenberg effect. An operational two-dimensional gas reservoir simulator has been developed which includes these effects.
