Assisted History Matching for Surface-Coupled Gas-Reservoir Simulation

The delivery-point pressures for gas reservoirs are known, and operators are obligated to supply gas into those downstream pressures. Therefore, reservoir-deliverability prediction must account for the pressure drop in the surface network. Also, this coupled system should honor historical attributes of pressures and rates. In this study, a modified Gauss-Newton method was used in conjunction with a nonlinear parameter-estimation algorithm to history match a surface/reservoir-coupled gas-reservoir simulation.
