TGS Awarded 2D Seismic Contract Offshore Sumatra, Indonesia

Perth, Australia (06 September 2024) - TGS, a leading global provider of energy

data and intelligence, has commenced the acquisition of a 2D seismic survey in

the Sumatra basin, Indonesia. The survey, conducted using COSL's HYSY 718

vessel, is expected to comprise between 5,500- and 6,500-line kilometers,

covering two regions.

This initiative marks a continuation of TGS's commitment to supporting

exploration efforts in Indonesia. Earlier this year, TGS announced the

completion of a multi-client 2D reprocessing project in the same basin which

aims to integrate key discoveries with available open acreage, complementing

TGS's existing extensive 2D and 3D seismic datasets in the region.

Kristian Johansen, CEO at TGS, stated, "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."

The seismic acquisition is expected to be completed by the end of Q4 2024.
