9 Reservoir Simulator for Unconventional Assets Locally refined grid structure enables multi well simulation Undefined gridding capability Multi-component porosity and permeability capabilities Natural fractures Matrix perm Kerogen perm Micro fracture perm Our Goal is to create a shale specific reservoir simulator with a simple, interactive user interface 9

10 Local Grid Refinement and Complex Gridding Capabilities Step 1 Step 2 or 3 Simple 3-D Fracture Network Calibrated to Match Surface Area of Mapped Fractures Experimental Gridding Code to Grid Complex Fractures Directly as Mapped Using Microseismic 10

11 Fracture Design and Well Optimization for Horizontal Wells Integration of fracture simulator, reservoir simulator and uncertainty Fracture planes can be defined in 3D space Initially simpler parallel fracture systems to be considered 11

12 Complex Fracture Model: From Microseismic Mapping to Statistical Design Tool New Complex Fracture Model maps fracture planes using microseismic data Statistical tools create complex grid defining natural fracture patterns Statistically equivalent fracture systems can be easily created and incorporated into well planing 12
