Modeling hydraulic fractures in finite difference simulators: Application to tight gas sands in Montana

The advantages of this technique are: (1) multiple fractures can be modeled in a single well and (2) heterogeneities within the fracture and reservoir can be accounted for. These advantages will lead to more realistic models and more accurate predictions; however, the most useful application of this technique may come in the fracture design stages. With this tool, various fracture geometries and scenarios can be tested quickly in the simulator, and the most economic scenarios selected and implemented. This will cause better fracture placement, and ultimately greater production.
