Hahonua Broadband Non-Exclusive 2D Seismic Survey
The Emerging Super Basin – Redefining Geological Understanding in the Gulf of Papua
The Hahonua Broadband Non-Exclusive 2D Seismic survey, acquired in cooperation with the Department of Petroleum and Energy (DPE) and project partner BGP, consists of over 13,000 km of long-offset, high-resolution broadband seismic data across the Gulf of Papua, designed to infill Searcher’s Lahara and Haere Seismic Surveys.
Fundamental in re-interpreting the geological story of the Gulf of Papua, the modern, high-quality dataset aids in identifying prospective structural and stratigraphic trends analogous to onshore PNG and the Northwest Shelf of Australia, with deep grabens believed to be filled with Palaeozoic and Mesozoic sediments, potentially associated with multiple unexplored petroleum plays.
