oa The Structure and Sequence Stratigraphy of Extensional Basins — A Case Study Offshore Deepwater Sarawak and Sabah

A structural and sequence stratigraphy study based on a reprocessed regional grid of 10,000 line kilometers of seismic covering the deepwater portion of offshore Sarawak and northwest Sabah was undertaken with the objective of improving the present understanding of the tectonics, paleo-depositional environments, and overall hydrocarbon potential of the offshore deepwater Sarawak and northwest Sabah Basins. This paper confines itself to a portion of the regional study which consists of the Oligocene to Early Miocene syn-rift section contained within extensional half-graben sub-basins situated beneath a regional Mid-Miocene Unconformity. Several of these haif-grabens exhibit ramp-flat-ramp geometries analogous to the productive Corsair Fault trend! Brazos Ridge Trend, offshore Texas, USA.
