A-25 MODELING OF FLUID EFFECTS IN COMPARTMENTALIZED AREAS AN OSEBERG SOUTH CASE STUDY 1 S.A. PETERSEN B.A. FARRELLY and B.I. BRAATHEN Norsk Hydro E&P PO Box 7190 N-5020 Bergen Norway Summary In order to evaluate the seismic (or any other physical) response of the subsurface one should be able to combine a model of the matrix with a model of the pore fluid distribution. The task becomes more especially difficult when the matrix distribution reflects a compartmentalization of the subsurface and/or if more fluid regimes are present. A method to construct such several models is presented and applied in a
