Constraint Optimization of Production in an Integrated Model using Pressure Control to Eliminate Slug Flow before the Separator
Conditional optimization is one of the best methods to increase production from hydrocarbon reservoirs. Integrated production modeling can optimize and manage production from reservoirs. In this research, a new method for optimizing integrated production systems is presented. The components of the integrated model are the reservoir, well, surface choke, pipeline, and separator models. The effect of separator inlet flow regimes and surface separator operation conditions on the efficiency of separator operation and oil production systems in this model cannot be neglected. This model includes the separator pressure controller and the objective function is to maximize the oil in the storage tank. The limitation of optimization is the non-formation of clotted flow at the inlet of the separator. The optimization model has excellent performance for optimizing integrated systems in stable, transient, and quasi-stable reservoirs. The optimization model can perform well in situations where the choke changes from critical to subcritical or vice versa. The amount of accumulated oil in the storage tank for the integrated model with clotted flow control is equal to BBL820, and for the integrated model without clotted flow control is equal to BBL 934.3 and for Olga software is equal to BBL 741.5. Using the optimal integrated model with clotted flow control, in addition to increasing oil production in the storage tank, also prevents the formation of slug flow.
