The goal of this work is to study the effectiveness (robustness, accuracy and speed) of an objective function in the context of seismic history matching; this aspect is the key component for a successful update of the reservoir model. Two main characteristics of the objective function are in focus: which seismic attributes should be matched to, and how to measure the matching. The sensitive factors currently studied are, the attributes at the simulation domain (pressure, water and gas maps, and combinations of these) and the metrics (Kendall Tau, L2 norm, Minimum ration, Pearson correlation) used to compare the two maps, from the seismic and from the model. The optimisation method used to perform the seismic history matching is an auto-adaptive differential evolution algorithm (SHADE). This study has been carried out on a North Sea field. Based on the results and analysis of the seismic history matching experiments, we are able to draw some practical recommendations, on what kind of objective function should be established to update the simulation model with seismic data.
