Proper field management for optimal performance of hydrocarbon reservoirs must capture the interdependence of the subsurface reservoir behavior and surface facility constraints. In this work we describe how full coupling improved development of a Saudi field by reducing water production by 30% while maintaining the target plateau for the required period of time. This was achieved by an iterative procedure that was able to devise an optimal producing strategy. The strategy involved time-dependent well production/injection rate allocations in response to field behavior. The strategy devised take into account production network constraints, network bottlenecks/under-utilization, and reservoir engineering complexities in producing three different reservoirs that make up the field. This work was realized by linking Saudi Aramco's in-house developed simulator (POWERS) with a commercially available surface network simulator (PE-GAP). The paper will highlight some of the major challenges in creating the link from engineering as well as from software/hardware perspectives. Due to this successful endeavor, the workflow will be applied to more fields. Furthermore connection to SCADA system for real-time monitoring is under developed. |
