New Approaches for Generally Constrained Production Optimization with an Emphasis on Derivative-free Techniques

摘要

Production optimization involves the determination of optimum well controls to maximize an objective function such as cumulative oil production or net present value. In practice, the satisfaction of general physical and economic constraints is also required, which typically results in optimization problems that are nonlinearly constrained. Examples of nonlinear constraints include maximum water cut and minimum oil rate for wells operating under bottomhole pressure control.
