- Shearwater GeoServices secures 4D monitoring projects from Equinor for Mariner and Heidrun fields.
- Projects will utilize Isometrix technology for seismic monitoring to optimize reservoir management.
- Shared ambition for production monitoring solutions to enhance long-term value creation from the fields.
Shearwater GeoServices has recently announced that it has secured two 4D monitoring projects from Equinor for the Mariner field in the UK North Sea and the Heidrun field in the Norwegian Sea offshore Norway. According to sources familiar with the matter, Shearwater will deploy its Isometrix technology for both surveys, applying 4D seismic monitoring to detect reservoir dynamics over time, optimizing 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. CEO of Shearwater, Irene Waage Basili, stated, “These projects underscore our shared ambition for pioneering and repeating production monitoring solutions. 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.” The Mariner field in the UK North Sea is expected to produce oil for the next 30 years, while the Heidrun field in Mid-Norway has been producing oil and gas since October 1995.
