Application of Nonlinear Adaptive Modeling for Rigorous Representation of Production Facilities in Reservoir Simulation

Abstract

Abstract A nonlinear adaptive modeling technique has been used to encode a rigorous deterministic model for optimal allocation of lift gas to wells. This model was incorporated into the Kuparuk Full Field Reservoir Simulator, for the purpose of evaluating the effect of additional lift gas compression capacity on production from the Kuparuk River Field. Simulation results indicate the nonlinear adaptive model technique yields more accurate lift gas allocations than the prior allocation paradigm which was based on nonlinear regression of field data.
