Searcher Seismic in conjunction with project partner TGS acquired over 12,000 km of 2D long-offset seismic data over the south eastern Papuan Basin.

The survey was acquired in water depths ranging from 30 m to 2,500 m and is still regarded as one of the most comprehensive seismic exploration datasets in the Gulf of Papua.

The original processing greatly improved understanding of the deep compressional fold belt and changed the industry’s prospectivity outlook by showing potential for new pre-Tertiary petroleum systems.

However, the area is plagued with a complex overburden and pushed the limits of traditional PSTM imaging. By applying broadband deghosting and a modern PSDM processing sequence, previous understanding of the basin is being fundamentally changed and there is fresh insight on old plays.

New PSDM data is available now. Gravity and magnetic data was also acquired and processed and available now.

Prior to the acquisition of the Lahara Non-Exclusive 2D Seismic Survey, Searcher Seismic and TGS reprocessed approximately 27,000 km of existing 2D seismic data – both Post-Stack and PSTM. View the Gulf of Papua 2D Reprocessing Package for further information.
