Bergen, 20 June 2025 -- Shearwater Geoservices AS ("Shearwater") has been
contracted by Equinor to perform a 4D towed streamer seismic survey over the
Tyrihans field in Norway. It is the first project awarded under the 2021
Equinor frame agreement following a recent extension for an additional two
years.

The one-month Norwegian Sea survey commences in early August. Shearwater will
deploy the Amazon Conqueror, using Isometrix technology. The survey follows
previous 4D campaigns for Equinor, most recently at the Mariner and Heidrun
fields in 2024. Applying the same proven technology to capture repeat
high-quality seismic data over the Tyrihans area will help understand changes
to the reservoir over time in the producing field and support future
production strategies to optimise output.

"The award reflects Shearwater's strong technical capabilities and consistent
operational reliability. Finding good solutions together with our clients is
always a priority for us. In this case, we can provide our client with updated
reservoir data to support long-term production optimisation and value
creation," said Irene Waage Basili, the CEO of Shearwater.
