Carnarvon Petroleum has commenced a new 3D seismic survey over the Dorado and Roc discoveries and adjacent prospects in Western Australia.

The latest survey, known as Keraudren 3D, will help in advancing the Dorado oil and gas field development. It will also support future drilling of potential targets in the region including Pavo and Apus. It will also provide better insights into the Caley, Crespin, Baxter and Milne intervals, all of which host significant quantities of oil and gas.

The survey will include an area of around 3,090km2 and will take around 70 days to complete. It encompasses a part of WA-437-P and WA-438-P, where Carnarvon owns a 20% and 30% interest respectively. The acquired data is expected to be available for interpretation early 2020, which will be used in field development planning and support a subsequent final investment decision planned in late 2020.

Carnarvon managing director Adrian Cook said: “A significant amount of work is currently being undertaken in relation to the Dorado oil and gas field and high grading a number of really exciting near field exploration targets, including Pavo and Apus.

“The Keraudren 3D survey is expected to provide important new data in support of both of these objectives.”

Three such 3D surveys were carried out in Australia’s North West Shelf that led to the Dorado and Roc discoveries in WA-437-P, also helping to identify multiple prospects and leads.

The announcement of Keraudren 3D comes after the company raised $50m capital to support its Australian offshore operations in February 2019, by issuing 151.6 million shares at a price of $0.33 per share.
