Improved Imaging in PP and PS, 4C Reservoir Characterization at the Grane Field

B-26 IMPROVED IMAGING IN PP AND PS 4C RESERVOIR CHARACTERIZATION AT THE GRANE FIELD Summary The 3D 4C acquisition at the Grane field was completed in May 2001. Both PP and PS have good quality and high utility value separately. In addition the PP and the PS data are complementary. The data set has high a potential for combined interpretation and analysis. In the following PP is synonymous with PZ the combined hydrophone and vertical geophone data while PS is the converted wave data. Introduction 1 J.P. FJELLANGER 1 A.-L. SKJERDINGSTAD 2 P. RISTE 1 M.
