History matching of production data using an updated static model. A case study from GullfaksHistory matching of production data using an updated static model. A case study from Gullfaks Μεταπτυχιακή Διατριβή Master Thesis 2017-02-062017enIn the present thesis, a new dynamic model of H1 segment in the Gullfaks field, Norway, is built based on an updated static model. The update of the static model refers to the re-interpretation of a more recent seismic dataset, which resulted into a new structural model. The new static model was the basis for constructing a new grid for dynamic modelling for history matching. Two different datasets were combined for this purpose. The first dataset was an already existing dynamic model for H1 segment (Lower Brent Group) and production data, while the second one was a 3D seismic dataset along with a static model of the overlying Upper Brent Group for the entire Gullfaks field (Petrel support dataset). The predictions of the new dynamic model were different compared to those of the initial dynamic model, which most probably reflects the impact of the updated structure. However, based on the interpretation of the available seismic data it is considered that the updated structure is more consistent to geological setting of the area that the seismic reveal. Thus, by having a more representative geological static model and the production data history matched on the new grid, we can conclude that the updated dynamic model can predict the future performance of the studied reservoir with more confidence.
