In this work, we investigate the efficient estimation of the optimal design variables that
maximize net present value (NPV) for the life-cycle production optimization during a single …

We consider a technique to estimate an approximate gradient using an ensemble of
randomly chosen control vectors, known as Ensemble Optimization (EnOpt) in the oil and …

We design a new and general work flow for efficient estimation of the optimal well controls
for the robust production-optimization problem using support-vector regression (SVR) …

Summary CO2-water-alternating-gas (CO2-WAG) flooding generally leads to higher
recovery than either continuous CO2 flooding or waterflooding. Although CO2 injection …

Single-objective well control problems have been studied for many years as one of the most
typical optimization problems by researchers worldwide. However, single-objective …

Production optimization under geological uncertainty is computationally expensive, as a
large number of well control schedules must be evaluated over multiple geological …

Robust and efficient optimization of post-history well production schedule under history-
matched geomodel known as closed-loop production management is crucial to achieve …

Abstract Water-alternating-gas (WAG) injection is a well known enhanced-oil-recovery
(EOR) method in the oil industry. In a previously published paper, we concluded that the …

With an increase in the number of applications of ensemble optimization (EnOpt) for
production optimization, the theoretical understanding of the gradient quality has received …

The economic and efficient development of petroleum resources can be realized by
dynamically adjusting the reservoir development scheme for the sake of higher recovery …
