New method for reservoir characterization and optimization using CRM-EnOpt approach

► We model a petroleum reservoir flow using a capacitance-resistive model (CRM). ► CRM combined with Ensemble Kalman Filter(EnKF) is used to characterize and forecast a priori unknown reservoirs. ► EnKF allows for time-dependent CRM parameters and non-linear effects that better approximate reservoir response. ► Ensemble based optimization (EnOpt) techniques are used to optimize injection rates for improved reservoir production. ► EnOpt uses EnKF in conjunction with CRM to optimize unknown reservoirs as they continue to produce.
