Shearwater Revolutionizes Production Monitoring for Equinor’s Oil Operations






TechWizard Feature: Shearwater to Monitor Production at Equinor’s Two Oil Fields

Shearwater GeoServices Enhances Production Monitoring for Equinor

Shearwater GeoServices 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. This collaboration will see Shearwater deploying its Isometrix technology for both surveys, utilizing 4D seismic monitoring to detect reservoir dynamics over time. By optimizing reservoir management and enhancing production efficiency, these projects aim to provide Equinor with valuable insights for long-term value creation.

Key Details:

  • Isometrix technology will be utilized for 4D monitoring at Mariner and Heidrun fields.
  • Previous monitor surveys were conducted in 2020, 2022 for Mariner, and 2018, 2021 for Heidrun.
  • Surveys are expected to take two months and will involve the SW Amundsen and an undershoot vessel.

“These projects underscore our shared ambition for pioneering and repeating production monitoring solutions,” said Irene Waage Basili, CEO of Shearwater. “Our dedication to providing top-tier seismic technology and expertise will support Equinor in optimizing resources for sustainable value creation.”

About Mariner and Heidrun Fields:

Equinor began production from the Mariner field in 2019, marking its first operated development in the UK North Sea. Located on the East Shetland Platform, the field is expected to produce oil for the next 30 years. Equinor holds 65.11% equity in Mariner, with partners including JX Nippon, Siccar Point, and ONE-Dyas.

The Heidrun field, situated off the coast of Mid-Norway, has been producing oil and gas since October 1995. It features the world’s largest floating concrete tension-leg platform and continues to be a key asset for Equinor in the Norwegian Sea.

With Shearwater’s advanced monitoring technology, Equinor aims to optimize production strategies and maximize the potential of these valuable offshore assets for years to come.
