Norwegian energy giant Equinor has contracted offshore seismic vessel player Shearwater Geoservices to perform a 4D towed streamer seismic survey over the Tyrihans field offshore Norway.
It is the first project awarded under the Equinor frame agreement, following a recent two-year extension.
The one-month Norwegian Sea survey begins in early August. Shearwater will deploy the 2015-built Amazon Conqueror, using isometrix technology.
The survey follows previous 4D campaigns for Equinor, most recently at the Mariner and Heidrun fields in 2024.
The survey over the Tyrihans area will be completed using identical proven technology and will help understand changes to the reservoir over time in the producing field and support future production strategies to optimise output.
“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, CEO of Shearwater.
