CGG, Searcher commence Carnarvon basin seismic project
PERTH, Australia -- Searcher Seismic, in conjunction with project partner CGG, has commenced the PSDM reprocessing of ~1,668 km2 of 3D seismic data in the Carnarvon basin, Western Australia.
The project comprises broadband PSDM reprocessing of the Western portion of the existing Foxhound 3D Seismic Survey, acquired by Searcher and CGG, and includes coverage to the 2016 Australian Acreage Release.
The survey is split into two portions—the Western cube, which lies northeast and on trend to Chandon, Martell and Io/Jansz fields, and the Eastern portion, which lies north-northeast and on trend to Pluto and Wheatstone fields.
“Originally acquired in 2009, the Foxhound 3D survey faced many challenging geophysical issues from a rugose seabed, a highly channelized Tertiary section and deep Triassic reefs,” Joshua Thorp, geoscience manager, Searcher Seismic, said. “Improving the phase control, particularly at the low end, and using an integrated geoscience approach to create a high resolution velocity model will enhance the imaging in the Jurassic and Triassic plays.”
“As we’ve seen from our nearby Drop Bear Ultracube data, this will allow exploration teams to move beyond AVO analysis and implement cutting edge QI techniques in this highly prolific basin,” Thorp added.
Final PSDM data will be available in third-quarter 2017.
