OSLO, Norway (11 February 2026) - TGS, a global leader in energy data and
intelligence, is pleased to announce the Ultra Profundo multi-client 2D survey
offshore Angola. The survey covers approximately 12,600 line kilometers and
Ramform Victory commenced operations earlier in Q1. Data acquisition is
estimated to be completed in approximately 100 days, with fast-track products
available in Q3. Full data processing is scheduled for completion in Q2 2027.

The Ultra Profundo multi-client 2D survey marks the first 2D multi-client
acquisition over Angola's ultra deepwater areas since 2015 and targets a highly
underexplored region. The survey delivers modern, long-offset seismic data
critical for imaging complex pre-salt and top-salt structures as well as basin
floor channel systems, significantly enhancing regional geological
understanding.

Kristian Johansen, CEO of TGS, commented: "Angola's ultra deepwater margin
represents one of the most exciting frontier exploration opportunities in West
Africa. Our Ultra Profundo multi-client 2D program delivers high-quality seismic
coverage needed to unlock pre-salt and sub-salt potential. By leveraging TGS'
acquisition and imaging capabilities, we will provide high-quality data
supporting future exploration activities."
