Petroleum System and Hydrocarbon Prospectivity of North West Luconia: The New Frontier in Sarawak Deep Water

Abstract

Summary This paper intends to discuss the hydrocarbon potential of an area in the North West corner of the Sarawak Deep water region, herein referred to as North West Luconia (NW Luconia). With very little well data available, the area could be considered a genuine deep water frontier. The study area is located on the junction of three major basins namely East Natuna, west Luconia, and North Luconia. The basin architecture and sedimentation pattern in the study area can be correlated to the nearby basins. The area extends from the present day shelf to an ultra deep water region with water depth in excess of 2000m ( figure 1b ). Due to data limitations, this study is largely driven by sparse regional 2D lines and conceptual regional models. Integration of 2D seismic interpretation, limited potential field data and well data suggest the possibility of a new hydrocarbon province in this frontier region. A number of potential exploration plays have been identified, some of which have never been tested in the deep water region of Sarawak.
