Shearwater GeoServices has secured two 4D monitoring tasks from Equinor for the Mariner area within the UK North Sea and the Heidrun area within the Norwegian Sea offshore Norway.
Shearwater will deploy its Isometrix expertise for each surveys, making use of 4D seismic monitoring to detect reservoir dynamics over time, for optimizing reservoir administration and enhancing manufacturing effectivity.
This would be the fourth Isometrix deployment for Mariner, complementing earlier monitor surveys in 2020 and 2022, and the third for Heidrun, following surveys in 2018 and 2021.
The surveys are anticipated to take two months and can be carried out by the SW Amundsen and an undershoot vessel.
“These tasks underscore our shared ambition for pioneering and repeating manufacturing monitoring options, and we look ahead to as soon as extra supporting Equinor in navigating in direction of the environment friendly optimization of assets.
“Our dedication to offering top-tier seismic expertise and experience will present Equinor with the insights wanted to proceed delivering long-term, sustainable worth creation from the Mariner and Heidrun fields,” stated Irene Waage Basili, CEO of Shearwater.
Equinor began manufacturing from the Mariner area in 2019 as its first operated growth within the UK North Sea. The sphere is anticipated to provide oil for the subsequent 30 years.
The Mariner area is positioned on the East Shetland Platform in UK Block 9/11a within the northern North Sea roughly 150 kilometers east of the Shetland Islands.
Equinor is the operator of Mariner with 65.11% fairness. The companions are JX Nippon (20%), Siccar Level (8.89%) and ONE-Dyas (6%).
Positioned about 175 kilometers off the coast of Mid-Norway in some 350 meters of water, the Heidrun area growth idea consists of the world’s largest floating concrete tension-leg platform.
The primary area on stream within the Norwegian Sea Heidrun has been producing oil and fuel since October 1995.
In June 2015 the brand new floating storage vessel Heidrun B acquired the primary barrels of oil from the Heidrun area. The vessel is designed to be completely moored for on the Heidrun platform, in one of many harshest offshore environments on the planet, for a minimum of 30 years.
