Optimization of Gas-Cycling, Voidage-Replacement and Production-Allocation for an Offshore Oil Field

A041 Optimization of Gas-Cycling Voidage- Replacement and Production-Allocation for an Offshore Oil Field B. Guyaguler* (Chevron) & J.W. Da Sie (Chevron) SUMMARY The application of an optimization methodology to a rate allocation case study for an offshore oil field is discussed. Conventional allocation methods available in most commercial simulators provide a familiar way for the reservoir engineers to carry out predictions while attempting to honor all desired field group and well operating conditions. However most of these conventional approaches are of a sequential nature and they fail to fulfill the requirements of this real field case. The conventional approaches fail
