TGS Secures Funding for a Series of Multi-client Programs in Southeast Asia

OSLO, Norway (14 August 2023) - TGS, a leading global provider of energy data
and intelligence, announces that it has secured funding for a series of multi-
client projects in Southeast Asia, which are anticipated to commence in late Q4
2023.

The program covers six months of new 2D and 3D seismic data acquisition, over
6,600 kilometers of legacy 2D seismic data reprocessing and 300,000 square
kilometers of 2D-cubed processing, tied together by a Facies Map Browser (FMB)
product that enables fast-track exploration of a regional hotspot. These
projects complement TGS' existing library across India, Bangladesh, Indonesia,
Malaysia, and Timor-Leste, encompassing 18,450 kilometers of 2D data, 70,237
square kilometers of 3D data, and 1,940,030 square kilometers of 2D-cubed data.

Kristian Johansen, CEO at TGS, commented: "This program demonstrates our
commitment to investing in energy data in Southeast Asia. The energy demand is
increasing in line with the region's rapid economic growth, driven by growing
populations and rising incomes. This growth brings with it a number of
challenges as governments and E&P companies strive to supply this energy
affordably and sustainably. Clients can remain confident that TGS is dedicated
to supporting them through these challenges with all their exploration,
production and CCS activities."
