### Abstract

A two-phase, single well numerical simulator capable of modeling the performance of either vertical wells, or horizontal wellbores drilled from a vertical shaft, has been developed. For the vertical wells, the model allows for the prediction of post-fracture performance. The hydraulically induced fractures can be specified as either infinite conductivity or finite (constant) conductivity, so that conventional, as well as massive treatments, can be modeled. All the equations generated by the model are solved simultaneously by the fully implicit, Newton-Raphson procedure. Both the numerical and mathematical developments are presented in detail.
