A New Insight on Structural Evolution of North Luconia in Deep Water Sarawak, Malaysia

North Luconia Basin of Offshore Sarawak has immense exploration potential. In shallow waters, the younger play is creamed while deeper and older plays remain largely unexplored in deep waters. Pre MMU and so called ‘sequence A’ plays are considered the main targets in deepwater Sarawak. Synthesizing seismic information along various sections, we conclude that the deformation style in Deepwater Sarawak has 2 dominant elements of faulting. (i) NE-SW striking rift related normal faults are developing on (ii) a NW-SE oriented basement fabric which has been deformed by NW-SE trending regional-scale strike slip faulting. The varying style of normal faulting is associated with thickness of Sequence A sediments. Laterally varying structural style in addition to the sediment thickness is related to transtensional/transpressional systems in the area. Apart from understanding the structural framework and trap configurations, a well defined structural styles can play a major role in guiding models of source rock and reservoir distribution and hydrocarbon plumbing in these uncalibrated plays.
