Paper submitted to the 2nd EAGE Workshop on New Discoveries in Mature Basins, by Tad Choi (TGS)
Summary
Offshore Sabah comprises two contrasting basin systems, the inboard Kinabalu Basin and the outboard Layang Layang Basin (Figure 1), each defined by distinct tectonostratigraphic histories and petroleum systems. The Kinabalu Basin hosts a post–Mid Miocene Unconformity (MMU) clastic play associated with a syn-kinematic fold and thrust belt, whereas the Layang Layang Basin contains a pre-MMU Oligocene system recently revitalized by major oil discoveries.
These results have triggered renewed exploration interest in underexplored Oligocene syn-rift settings and highlight the broader implications for the Dangerous Grounds region.
