Dunnart Non-Exclusive 2D Seismic Survey

Facilitating Exploration in the Carnarvon Basin with High Quality Data

The Dunnart Non-Exclusive 2D Seismic Survey, strategically placed within the core of the Exmouth Plateau, dispenses comprehensive long-offset broadband data, stoking exploration excitement within this promising yet remarkably pristine territory flush adjacent to multiple fields.

Encompassing over 540 kilometers within the Carnarvon Basin’s rich prospective belt, and favourably positioned among some of the North West Shelf’s sizeable gas finds, the Dunnart 2D Seismic Survey grants a robust blueprint for future area assessments. It delivers excellent, well-tied seismic data, enhancing comprehension of the region’s geological and stratigraphic framework. The invaluable broadband data gleaned from this survey paves the way for informed exploration choices and potential uncovering of new hydrocarbon reserves ensconced within the expansive Carnarvon Basin.
