In order to improve the design of advanced wells, performance such wells needs be carefully assessed by taking reservoir uncertainties into account. This research aimed develop data-driven proxy models for simulation and assessment oil recovery through under uncertainty. An artificial neural network (ANN) was employed create accurate computationally efficient as an alternative physics-based int...

Abstract A Derivative-Free Trust-Region (DFTR) algorithm is proposed to solve the robust well control optimization problem under geological uncertainty. (DF) methods are often a practical alternative when gradients not available or unreliable due cost function discontinuities, e.g., caused by enforcement of simulation-based constraints. However, effectiveness DF for solving realistic cases heav...
