| Summary: | It is common in industry to analyze reservoir characterization using geological data and early geophysics evaluation. However, there are limited studies about utilizing offshore instrumentation and monitoring data to effectively characterize reservoir description. These under-utilized dynamic data are usually used for evaluating reservoir production yet to be used for better understanding reservoir characterization for reservoir optimization purposes. This study proposes a semi-analytical approach to utilize reservoir pressure, production and injection data to ultimately estimate and monitor the transmissibility of a leaking fault. A history of average reservoir pressure and production rate is matched to determine fault status. The reservoir pressure and production/injection history in different reservoir compartments are evaluated to estimate flux rate across leaking fault. An offshore case study consists of two reservoir compartments separated by a fault with unknown connectivity and supported by large active aquifer and water injection was implemented. The history match honored the reservoir pressure and the re-allocated production/injection data in each compartment. |
