Seismic and geophysical data company TGS has been awarded a 2D seismic survey in Indonesia’s Sumatra Basin, the company said on Sep. 6.

The survey, conducted using China Oilfield Services’ HYSY 718 vessel, will cover two regions, comprised of between 5,500 km and 6,500 km. The seismic acquisition is expected to be completed by the end of the fourth quarter.

Earlier this year, TGS completed a multi-client 2D reprocessing project in the Sumatra Basin that integrated key discoveries with available open acreage. The new survey aims to complement TGS’s existing 2D and 3D seismic datasets in the region.

TGS CEO Kristian Johansen said North Sumatra has been the site of major discoveries in the past few years.

“With this being our sixth consecutive acquisition project offshore Indonesia, TGS remains dedicated to advancing exploration in the region. Our high-quality seismic data continues to shed light on crucial play concepts, extending exploration potential into open acreage and unlocking exciting opportunities within the Sumatra basin,” he said.
