Enhancement of Regional EOD of the Sarawak Basin Using Multiple Geological Data Calibration

Sarawak Basin is a hydrocarbon prolific sedimentary basin that has been explored for decades since 50s. As a major hydrocarbon producing basin in SEA, enhancing subsurface reservoir sand distribution remains essentially important to support exploration efforts in the basin. Hence, any tool that clarifies the distribution of reservoir sands is worth pursuing. This paper discusses an update of paleogeography of the Sarawak Basin and its succession focusing on Cycle I, II and III based on the latest geological data available. The paleographic setting provides further insight of temporal and spatial distribution of depositional facies developed in support to future hydrocarbon exploration and exploitation in the basin.
