Abstract
There is generally a high uncertainty in identifying fracture patterns due to fracture interference in shale gas reservoirs. In this work, we studied five complex and irregular hydraulic fracture patterns within one perforation stage, where the fracture half-length varies, and compared well performance using a commercial reservoir simulator. Results show that there is a big difference in gas recovery between different patterns. We also studied the effects of matrix permeability, cluster spacing and fracture conductivity on reservoir performance. This work will provide critical insights into characterization of hydraulic fracture geometry in shale gas reservoirs.
