Abstract
The natural gas has recently become the main source of energy and determining the optimum production of gas wells is very important for efficient production planning. A modified isochronal test was performed as a tool in evaluating a hydraulic fracturing treatment on a gas well. Pressure test analysis was performed to investigate the success of the treatment. Inflow performance curves, and pressure and production forecast were also performed using diffusivity equation as well as Material Balance equation. The study was conducted on a gas well in a Middle Eastern reservoir.
The analysis shows that the hydraulic fracturing treatment on the gas well was successful through an improvement in well productivity. Reservoir properties were also determined from the pressure test and the inflow performance curves were successfully generated and can be used for further study.
