Numbat Non-Exclusive 3D Seismic Survey

High Resolution Data for Enhanced Exploration

The Numbat Non-Exclusive 3D Seismic Survey covers an estimated 140 km², strategically positioned on the southern flank of the Barrow Sub-basin, celebrated for its abundant oil and gas reserves. This materialises an unprecedented uplift in data accuracy, revealing enticing new opportunities for exploration in this highly productive domain.

Designed to provide superior resolution coverage, the Numbat Survey delineates Early Cretaceous and Triassic prospects and leads. This comprehensive dataset augments understanding of the region’s geological intricacies, enabling more insightful exploration and optimised development strategies.
