Numerical Simulation Study on Diamond-Shape Inverted Nine-Spot Well Pattern

A newly derived nonlinear flow numerical simulator was used to study on the diamond-shape inverted nine-spot well pattern based on laboratory experiment and actual field data. The optimum artificial fracture penetration ratio, flow conductivity, and condition of converting the corner-wells to injection wells were presented on the basis of 37 concept model well plans. Finally, the formation pressure gradient distributions of different well plans were provided and analyzed.
