Searcher begins 2D broadband PSDM

Searcher Seismic is currently reprocessing two regional seismic datasets in the Philippines and Papua New Guinea.

In the Philippines, the Pala-Sulu seismic survey was acquired in 2011. The dataset is currently being reprocessed with broadband deghosting and Pre-Stack Depth Migration (PSDM) to further enhance the quality of the existing data.

The Pala-Sulu survey is being processed following the recently completed Mialara 2D new acquisition seismic survey, creating a comprehensive tied 10km grid over the PECR5 blocks.

The Perth-based company is also reprocessing the Lahara 2D seismic survey in Papua New Guinea, which includes over 12,000km of 2D long-offset seismic data over the southeastern Papuan Basin.

The Lahara survey was acquired in water depths ranging from 30 to 2500m. According to Searcher, Lahara is regarded as one of the most comprehensive seismic exploration datasets in the Gulf of Papua. 

Rachel Masters, global sales manager, Searcher, said the survey improved the understanding of the deep compressional fold belt and changed the prospectivity outlook by showing potential for new pre-tertiary petroleum systems. 

“However, the area is plagued with a complex overburden which 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 into old plays,” Masters said.

Last month, Searcher Seismic and BGP commenced the Bilby Non-Exclusive 2D seismic survey in Bedout Sub-basin and Broome Platform in Western Australia. It comprises of approximately 12,300km of 2D long-offset, high-resolution broadband data over 2x4, 4x8 and 8x8 km grids.
