Effect of Integration Study in a Field Development Plan-Case Study

Nowadays reservoir modeling and simulation are performed without considering mutual influence of equipments in surface facility. This will result in overestimating amount of produced oil in specified time period. The reason why this happens is that individual reservoir simulation has bottom hole pressure as controlling parameter but integrated reservoir simulation has controlling parameter of first stage separator pressure. In this paper, the effect of controlling parameters in integrated and non-integarated reservoir simulation has been explained. And then we compared results of these two cases in one Iranian field with two reservoirs. It was shown that non-integrated study has overestimated produced oil with respect to integrated one.
