A Global Search Supported CAHM Case Study Improved by Geoscientific Expertise

D-46 A GLOBAL SEARCH SUPPORTED CAHM CASE STUDY IMPROVED BY GEOSCIENTIFIC EXPERTISE Abstract 1 History Matching (HM) is one of the most comprehensive steps in reservoir analyses. It is strongly dependent on expertise from different geoloscientific sources and needs relatively long time to arrange a satisfactory reservoir data set which can be accepted as the basis for reservoir production forecasts. In this study local and global optimization methods were used to study advantages and disadvantages of computer assisted history matching (CAHM) for a North German Gas Field. Starting from a geological base model the differences between measured and calculated wellbore
