A correction methodology for explicit coupling between reservoir and production system simulators

Various methodologies to model the coupling of reservoirs and production systems have been applied in the oil industry in recent years due to the need to model properly the integrated solution of models that represent the flow of fluids through the reservoir to the surface. Explicit methodology can be an efficient choice to integrate simulations because allows coupling adequate simulators to model the whole system and also to grant flexibility in study of well management alternatives. Several authors have shown the limitations of explicit methodology coupling reservoirs and production systems, such as errors due to the inadequate choices of time step and boundary conditions. The objective of this work were formulated a theoretical foundation to support the adopted IPRc correction methodology, comparing with observed well bottom hole pressure data from reservoir simulation, and validate explicit coupling methodology for producer wells, applying in cases of known response in common situations of well operation in production and injection of fluids. The explicit coupling between reservoir simulator and production systems was implemented obtaining satisfactory results when compared with uncoupled and decoupled methodologies221111126ASME - 31st International Conference on Ocean, Offshore and Arctic Engineerin
