Abstract

The increasing demand of energy and the limited reserves of conventional reservoirs leads the industry to enhance and develop low permeability reservoirs in recent years which become increasingly important than ever before. Shale gas one of these reservoirs which has very low permeability and the production from this formation has been and continues to be challenging. Horizontal wells with multiple hydraulic fractures are the proven technology to produce economically from gas shale formations. One of the issues in shale gas reservoirs is to have an accurate and reliable estimation of ultimate recovery.;The purpose of this research was to use the initial production history of Marcellus shale in order to predict the ultimate gas recovery of multiple fractured horizontal wells. A commercial reservoir simulator was utilized to create reservoir model with horizontal well fractured in multi stages.;The impacts of a number of reservoir and fractures parameters were investigated. Matrix porosity, number of hydraulic fracture stages, and fracture half-length were found to impact on the gas recovery.
