Paper presented at the SPE Norway Subsurface Conference, April 17, 2024
Paper Number: SPE-218465-MS
... Abstract Assisted history matching is a pivotal process in optimizing reservoirs models through the calibration to observed well and pressure field data. Robust reservoir forecasting is essential for effective asset management and development planning; however, it is significantly impacted...

...Problem Definition The 200 initial and 100 updated Grane reservoir models showed an excellent overall history match with respect to production data at the field level, but some discrepancies were observed in distal localized regions of the field. These regions were under evaluation as targets...

... and drainage history very complex. Thus, achieving a full field history match in the Fensfjord reservoir through deterministic modeling has always been a challenge. Current STOIIP estimates indicate that there is room for several more producers. However, identification of target areas for future wells...

... be achieved within an acceptable time frame and simulation may last days or weeks. These long run times cause a delay in achieving a robust history matched or production forecast model as it constrains the ability to effectively characterize the uncertainty range of subsurface parameters and potential...

... AICD model were thoroughly investigated to derive scenarios, that could explain this discrepancy. The most likely scenario gives a good history match for both pressure and tracers and gives extra insight into key reservoir parameters, zonal inflow and the effective behavior of the AICDs during multi...

... history from one test producer. A key objective of the modelling effort was to take an uncertainty-centric approach that could integrate all available data. The methodology of this approach is presented, and its benefits and challenges are discussed. The quality of the automated history matching is shown...

... Abstract Ensemble-based history matching methods have received great attention in reservoir engineering. In real applications, small ensembles are often used in reservoir simulations to reduce the computational costs. A small ensemble size may lead to ensemble collapse, a phenomenon in which...

... is mitigated by conditioning the model with data through data assimilation, a process known in the oil industry as history matching. Several recent advances are being used to improve history matching reliability, notably the use of time-lapse data and advanced data assimilation techniques. One of the most...
