We have used a three-dimensional, multi-phase reservoir model to history match the post-fracture performance data of two separate completions in the complex, low permeability Travis Peak formation. This model consists of a two-layer, two-phase (gas-water) reservoir in communication with the wellbore via a vertical hydraulic fracture. The two-layer, two-phase reservoir model accurately matches post-fracture production data and pressure buildup test data from each Travis Peak completion interval.

Our results show that the properties of the hydraulic fractures determined by this reservoir simulation are in good agreement with the fracture properties determined by a three-dimensional (3-D) fracture propagation model. In addition, reservoir simulation history matching determined that a multi-layer reservoir system was necessary to model the performance in the lower Travis Peak completion interval.
