Abstract

The deepwater Kutei basin is one of the most prolific basins in the Makassar Strait but until recently, the exploration has focused on easy to find structural traps. Basin floor fans often form stratigraphic traps which could be difficult to map on seismic. CSEM, which is not governed by elastic properties but rather electric properties is sensitive to saturation. By imaging resistivity distribution, CSEM helps detect not only the difficult traps like basin floor fan but also help in delineating the trap extent which eventually gives better prediction of net rock volume and hydrocarbon volumes.
