Method & Evidence

AimTo develop and validate a state-space representation of the Capacitance-Resistance Model (CRM) for improved real-time reservoir management and control.

MethodGrey-box system identification and state-space modeling

ProcedureThe CRM was reformulated into a state-space (SS-CRM) representation. This SS-CRM was then used to model two distinct reservoir systems (homogeneous with flow barriers and channelized). The performance of different CRM representations (integrated, producer-based, and injector-producer-based) within the state-space framework was analyzed, and parameter sensitivity was assessed.
