Carnarvon Basin:


The Carnarvon Basin is a prolific hydrocarbon province that continues to attract high levels of activity due to ongoing modern and high-quality seismic dataset acquisition and reprocessing, revealing attractive exploration targets. The offshore part covers approximately 535,000km2 with water depths up to 3500m, and is transitional southwards into the Perth Basin and northeastwards into the Offshore Canning and Roebuck Basins. The basin is a subsiding continental platform characterized by a thick Triassic succession and overlain by thinner Jurassic and younger sequences. A N-S to NE-SW structural trend created large fault-bounded structures that are proven to be highly successful to date. Gas has been the main phase of hydrocarbons discovered but exploration drilling results over the last ten years have hinted at the presence of an oil-prone Triassic petroleum system in addition to the proven gas play. The recent discovery of significant oil and liquid-rich gas accumulations in the neighboring inboard Bedout Sub-basin, within Triassic reservoirs sourced from mature Triassic organic-rich rocks, has again highlighted the potential of the oil play extending further west and outboard into the Carnarvon Basin. TGS has 110,920.1 km2 and  7,700 km of existing modern, high-quality 3D and 2D data respectively, that covers large swathes of areas of the Carnarvon Basin.
