Triok Broadband Non-Exclusive 2D Seismic Survey

Triok Broadband Non-Exclusive 2D Seismic Survey

Following the successful acquisition of the Solomon Sea 2D in the Northern Basins of Papua New Guinea, the Triok Non-Exclusive 2D Seismic Survey comprises of 3,845.3 kilometres of 2D long-offset, high-resolution, broadband seismic and offers an extensive regional coverage of the Cape Vogel Basin and Huon Gulf. 

The survey follows the recent spark in activity offshore the Gulf of Papua, where modern broadband processing techniques unveiled exciting new potential in the area. 

Modern and historic seismic coverage in the area is sparse and thus the survey has been designed to understand the tectonic history and image deep structures within the areas. The Triok Non-Exclusive 2D Seismic Survey will provide new insight into unexplored areas of Papua New Guinea and provide further knowledge into the area’s architecture and regional evolution. 

Fast track PSTM data will be made available by April 2019, with the final PSDM data expected to be available July 2019.
