PGS delivers data from North Carnarvon Basin survey

Norwegian seismic services provider PGS has made final data available for the Mawson multi-client 3D seismic survey covering the prospective North Carnarvon Basin offshore Australia.

PGS said on Thursday that the Mawson 3D survey applied a triple-source GeoStreamer 3D survey design and delivers seismic data with prestack AVO/AVA fidelity to image the deep Triassic fault blocks of the Outer Exmouth, Carnarvon Basin.

According to the company, this multi-client 3D survey was acquired over ten weeks during March and April 2019, with initial fast-track data delivered to prefunders in almost realtime to enable early interpretation.

Processing and imaging of the full integrity data are now complete. This is an area that PGS believes will be relevant for 2020 licensing.

Rick Irving, PGS VP for new ventures and sales for Australasia, said: “The survey offered an extremely fast method of delivering a new understanding of held acreage for license-holders while expanding coverage to vacant acreage that may provide future licensing opportunities.

“It made sense commercially and adds a greater understanding of the geological settings. This was made possible due to the integrated approach PGS took to project planning, acquisition, and imaging.”

The North Carnarvon Basin is a frontier area that contains a variety of structural/stratigraphic trap styles within the prospective Triassic fault blocks and Upper Jurassic sediments. The area is on trend with existing gas accumulations to the south and close to existing infrastructure.
