The one-month survey will commence in July 2026 and deploy Shearwater’s Isometrix multi-component streamer technology to deliver high-quality, repeatable time-lapse seismic data to support reservoir monitoring and field management.

The survey is designed with the potential for an undershoot, as reflected in the contractual scope, to enhance imaging and ensure continuous coverage around field infrastructure.

“Shearwater welcomes this award by Adura, extending our long-standing collaboration at the Mariner field, supporting the continued optimization of this complex and long-life asset,” said Irene Waage Basili, CEO of Shearwater. “Monitoring reservoirs in existing fields is essential to extending field life, optimizing production, and supporting energy security.”
