All four phases of CGG’s BandaSeis 2-D BroadSeis multiclient program targeting the Banda Arc around East Indonesia and Timor Leste have been fully processed and are ready for delivery, the company said in a news release.

Totaling more than 14,000 km of broadband seismic data, the program was acquired in cooperation with the Indonesian Directorate General of Oil and Gas (Migas) and the Timor Leste National Petroleum Authority (ANP), the release said. The data was processed to pre-stack depth migration (PSDM) in four stages in CGG’s Singapore imaging center, with the final phase being delivered at the end of the second quarter of 2015.

CGG said the final seismic images will help explorationists understand the geological development and prospectivity of the Banda Arc, which is located in the active collision zone between the Australian continental plate and the Indonesian island arc system.

The PSDM volumes will provide information on Mesozoic sedimentary successions, including the deltaic and marginal marine Lower to Middle Jurassic Plover Formation (and correlative successions) which contains excellent reservoir-quality sandstones in the nearby Laminaria and Corallina Fields (Bonaparte Basin, Australia), together with the Abadi and Bintuni Bay gas fields of East Indonesia, the release said.

The BandaSeis 2-D seismic data is being correlated with new, multi-pass satellite seep data from NPA Satellite Mapping to identify potential hydrocarbon migration pathways and confirm the potential of an offshore petroleum system, the release said. This is being done because the Banda Arc area has abundant onshore and offshore oil and gas seeps and similarities with geologically contiguous Mesozoic and Cenozoic successions in Australia where numerous petroleum systems exist and have been exploited, according to CGG.

The overall program will be complemented by a tectonic and structural interpretation due to be completed by GeoConsulting by year-end 2015. GeoConsulting geologists have already been able to highlight new plays in the Mesozoic section due to the BroadSeis data, CGG said.
