Abstract
In the daily operation of an oil and gas production system, a lot of decisions have to be taken that affects the volumes produced and the cost of production and the necessity of optimized products or processes prevails in many sectors of industry. Reservoir model is an important piece of the solution which should be updated by time. In time updating not only is important for reservoir modeling but also makes a lot of benefit along optimization. Task of gathering data comes up with monitoring tools and it’s inevitable. Before applying every solution or plan, it must have economic justification. In this study one of the Iranian offshore oil reservoir was studied to depict necessity of optimizing 29 wells of injection/production rate. At first, the reservoir model was constructed by ECLIPSE 2012 simulator, and then linked with coding program which is contained Genetic Algorithm. Finally by applying optimization in a certain period of time, some wells did not need to be closed compare to real operational stage and final recovery increased about 5.3 percent. This study shows monitoring play a main role for this field to increase the oil recovery. In addition, this job illustrates a scenario for wells operation.
