THE latest technology will be applied to PSDM reprocessing of 7,000km of 2D seismic data acquired by Searcher Seismic in the Browse Basin off the coast of Western Australia.

The project comprises broadband PSDM reprocessing of Searcher’s existing Vampire 2D Seismic Survey and includes coverage to the 2016 Australian Acreage Release.

Originally acquired in 2010 with an eight km streamer, the Vampire 2D Seismic Survey ties key exploration wells in the prolific Browse Basin.

Initially designed for industry as a tool for understanding the regional structural and stratigraphic framework of the Browse Basin, the PSDM reprocessing takes advantage of recent technological advancements to further unlock the potential of this highly prospective area.

“Applying broadband deghosting not only improves the end result, but allows greater resolution for the PSDM velocity model building at all levels,” said Joshua Thorp, geoscience manager for Searcher Seismic.

“Implementing an anisotropic PSDM workflow improves both the quality of the data and more importantly, the AVO attributes derived from this long-offset well tie dataset,” Mr Thorp added.

The PSDM reprocessing is being undertaken by WesternGeco and provides a high value solution to those wanting to understand the Browse Basin in a regional context.

Final PSDM data will be available in Q4, 2016.

Olympus processing underway

Searcher Seismic has also reported that processing of the Olympus 3D Reprocessing Project in the Carnarvon Basin has commenced at DownUnder GeoSolutions’ Perth facility.

The project, in cooperation with Spectrum, comprises the reprocessing of 20 existing 3D datasets through a broadband Pre-Stack Time and Depth Migration (PSTM and PSDM) workflow.

The project extends northward from the Rankin Platform and covers an extensive fairway of high quality Jurassic reservoirs in the Angel, Calypso and Legendre Formations, with multiple potential sources including the Dingo Claystone and the Muderong Shale.
