Oil recovery can be enhanced by maximizing the well-reservoir contact using advanced wells. The successful design of such wells requires an appropriate integrated dynamic model of the oil field, well, and production network. In this study, the model of advanced wells developed in the dynamic multiphase flow simulator OLGA^® is linked to a reservoir model to develop transient fully-coupled well-reservoir models for the simulation of oil recovery through advanced wells. The obtained results from the developed models in OLGA are compared with the results from the widely used MultiSegment Well (MSW) model. Flow Control Devices (FCDs) are the key component of advanced wells and the functionality of the main types of FCDs is investigated. According to the obtained results, by employing advanced wells with an appropriate completion design, the production of unwanted fluids (water and/or gas) can be highly reduced while the oil recovery is slightly increased compared to using conventional wells. Besides, by comparing the performance of the OLGA and MSW models, it can be concluded that OLGA is a robust tool for conducting an accurate simulation of oil recovery through advanced wells. However, running such simulations with OLGA is relatively slow and may face convergence problems.
