History Matching with Respect to Reservoir Structure

A013 HISTORY MATCHING WITH RESPECT TO RESERVOIR STRUCTURE Abstract 1 A practical method for history-matching with respect to geological fault properties (fault displacement average dip and strike smear-gouge-ratio shale-smear-factor etc.) is presented. The method is based on coupling commercial software for fault modelling with a reservoir simulator. The history-matching and control of these tools are performed using standard optimization routines in MATLAB. Both large seismic faults as well as small subseismic faults can be modelled. For the large faults the simulation model grid is automatically deformed in each iteration of the history-matching process. The sealing effect is based on an
