This sheet can be used to perform a complete well model (IPR) for hydraulically fractured oil reservoirs. It can be used to predict the production rate increase after a hydraulic fracture treatment. The sheet also provides: 1.      Productivity index (PI) calculations before frac.2.      PI calculation post-fracturing.3.      Dimensionless fracture conductivity (CFD).4.      Negative skin due to Frac.5.      The fold of increase (FOI) […]
