Grane - Converted Wave Imaging for Well Planning

B020 Grane - Converted Wave Imaging for Well Planning J.P. Fjellanger* (Hydro Oil & Energy) F. Bøen (Hydro Oil & Energy) & K.J. Rønning (Hydro Oil & Energy) SUMMARY The Grane reservoir is difficult to image with ordinary pressure wave (PP) seismic data. In 2001 Hydro acquired a 3D multi-component (4C) survey with ocean bottom cables in the north of the field. A new 4C survey was shot in the south in 2003. The two surveys together cover the whole Grane field. Converted wave data (PS) has proven to give a much better definition of the reservoir sand on Grane
