Searcher Seismic starts reprocessing Carnarvon data

Searcher Seismic, together with project partner, CGG, has reported that the PSDM reprocessing of 1,668 square kilometers of 3D seismic data in the Carnarvon Basin, Western Australia has started. 

The multi-client company said on Thursday that 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 North-East and on trend to the Chandon, Martell and Io/Jansz fields, and the Eastern portion which lies North-North-East and on trend to the Pluto and Wheatstone fields.

Searcher said that final PSDM data will be available in the third quarter of 2017.

Joshua Thorp, Geoscience Manager for Searcher Seismic, said: “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.

“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.”

Thorp added: “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.”
