Shearwater Geoservices AS secured a contract from Adura Operations Limited to carry out a towed-streamer 4D seismic survey at the Mariner field, located in the UK North Sea.
In addition, the campaign will last approximately one month and is scheduled to start in July 2026. The objective will be to obtain repeatable, high-quality seismic data to support reservoir monitoring and field management.
The project scope covers approximately 220 km² of seismic acquisition using Shearwater’s SW Tasman vessel and its established OBN deployment capabilities and techniques. The SW Gallien vessel will provide the seismic source.
Isometrix technology for time-lapse data
The survey will use Isometrix multi-component seismic streamer technology. This solution will improve seismic image quality and provide key insights into reservoir changes over time.
The two-month survey will deliver high-resolution OBN data that will help improve understanding of the reservoir across the entire Jackdaw field.
Likewise, the contractual scope includes the possibility of an acquisition under the field infrastructure. This configuration aims to improve coverage around existing facilities and strengthen the continuity of the data obtained.
Shearwater strengthens its presence at Mariner
Irene Waage Basili, CEO of Shearwater, highlighted that the contract expands the company’s collaboration with Adura at the Mariner field. She also noted that monitoring existing fields is essential to extend their service life, optimize production, and support energy security.
“We look forward to working with Adura on this OBN project. The award strengthens Shearwater’s leading position in the global OBN market and our extensive technical capability to serve operators in the basin,” said Irene Waage Basili, Chief Executive Officer of Shearwater.
Furthermore, Shearwater maintains a strong position in marine geosciences through vessels, seismic equipment, and proprietary software for processing subsea subsurface data.
