Searcher Seismic is announced the completion of the Roho Airborne Gravimetry acquisition, a regional multi-client airborne gravity, gravity-gradiometry and magnetics survey covering the transition zone of the Gulf of Papua.
The Roho Airborne Gravity, Gravity-Gradiometry and Magnetic Survey covers approximately 60,700 square kilometres (52,700 line km) along the southern coast of PNG. The survey compliments several marine seismic and geochemical projects recently completed by Searcher aimed at assessing the hydrocarbon potential of the Gulf of Papua and adjacent Coral Sea areas, offshore PNG. The data were acquired with a 1km line spacing in the northern Gulf of Papua, and 2km line spacing extending along the coastline to SE PNG.
Much of the area covered by the Roho Survey were comprised of shallow water transition zone environments where seismic operations are difficult and expensive. The survey was acquired by CGG Multi-Physics, using a Basler BT-67 and a DHC-6 Twin Otter twin turbine fixed wing aircraft.
Andrew Weller, Geoscientist and Asia-Pacific Sales Manager for Searcher Seismic, said the survey was designed to bridge the gap between the onshore areas of PNG where many wells have been drilled, providing good geological control points, with the offshore regions in the Gulf of Papua and Coral Sea, where a substantial database of new, high quality seismic data is now available, and well data is sparse or absent all together.
The Roho Survey provides the exploration industry with the largest and most coherent dataset over a significant portion of the Gulf of Papua’s transition zone environment. The Roho Survey complements Searcher’s existing 2D seismic coverage which currently stands at over 87,000 kilometres, 3,888 square kilometres of 3D as well as a geochemical survey, offshore Papua New Guinea.
