O-28 MODELLING LATERAL FLUID FLOW IN THE SMØRBUKK AREA OFFSHORE NORWAY Abstract 1 H. BORGE 1 and E. VIK 2 1 SINTEF Petroleum Research 7465 TRONDHEIM Norway 2 STATOIL The Halten Terrace offshore Norway consists of three pressure regimes: A highly overpressured (>200 bar) western part an intermediately pressure (75-200 bar) region in the south and a normally pressured (0-75 bar) eastern flank. The Smørbukk and Lavrans fields are located within the normally pressured region adjacent to the fault that separates the highly and normally pressured regimes. The observed overpressures within these two fields vary both vertically and laterally (Table
