Bergen, 13 March, 2024

Shearwater GeoServices Holding AS (“Shearwater”) is pleased to announce the award of two 4D monitoring projects by Equinor for the Mariner field in the UK North Sea and the Heidrun field in the Norwegian Sea, Norway.

Shearwater will deploy its state-of-the-art Isometrix technology for both surveys, applying 4D seismic monitoring to detect reservoir dynamics over time, for optimising reservoir management and enhancing production efficiency. This will be the fourth Isometrix deployment for Mariner, complementing previous monitor surveys in 2020 and 2022, and the third for Heidrun, following surveys in 2018 and 2021.

The surveys are expected to take two months and will be carried out by the SW Amundsen and an undershoot vessel. The award demonstrates Shearwater’s capability in delivering high-quality, insightful data, supporting Equinor’s vision for sustainable reservoir utilization.

“These projects underscore our shared ambition for pioneering and repeating production monitoring solutions, and we look forward to once more supporting Equinor in navigating towards the efficient optimisation of resources. Our dedication to providing top-tier seismic technology and expertise will provide Equinor with the insights needed to continue delivering long-term, sustainable value creation from the Mariner and Heidrun fields.”
