Abstract

The Weda Bay area represents a frontier exploration hydrocarbon opportunity in SW Halmahera, Eastern Indonesia. Newly acquired seismic data over the Weda Bay Basin, indicates in excess of 7km of Tertiary sedimentary section. Source rocks are believed to be present over much of the basin and have the potential to generate both oil and gas. Hydrocarbon expulsion features are present in many of the seismic lines acquired. The basin flanks are currently within the generative window for both oil and gas. Potential play types are both reefs and stacked compressional clastic structures. All elements of a working petroleum system have been demonstrated and blocks have been proposed for release in April 2011.
