TGS Q2 2022 Revenue Update

OSLO, Norway (8 July 2022) - Based on preliminary reporting from operating
units, TGS management expects net revenues for Q2 2022 to be approximately USD
230 million, compared to USD 72 million in Q2 2021. Net POC revenues* are
expected to be approximately USD 136 million, compared to USD 54 million in Q2
2021.

Kristian Johansen, CEO at TGS, commented: "Q2 2022 was another solid quarter
with late sales of close to USD 100 million, driven by a further improvement of
activity in frontier areas and transfer fees. With a quarter-end cash balance of
approximately USD 255 million in addition to an undrawn revolving credit
facility of USD 100 million, we have a solid financial position that can
comfortably fund the recently announced M&A transactions."

TGS will release its Q2 2022 results at approximately 07:00 CEST on 21 July
2022. CEO Kristian Johansen and CFO Sven Børre Larsen will present the results
during a live webcast at CEST 09:00.

*For the purpose of Segment reporting, multiclient revenues committed prior to
completion of projects are recognized on a percentage of completion ("POC")
basis. This differs from IFRS reporting where revenues committed prior to
completion are recognized when the customers receive access to the finished
data.

Adjustments between preliminary IFRS and Segment revenue numbers for Q2 2022:

Preliminary IFRS reported revenue: USD 230 million
- Revenue recognized from performance obligations met during Q2 for completed
projects: USD 127 million
+ Revenue recognized under POC during Q2: USD 33 million
= Preliminary net segment reported revenue: USD 136
