Mermaid Subsea Services (UK) has announced the successful and safe completion of a well intervention on the Teal P2 well, located in the Central North Sea.
The operation, executed from the Island Valiant vessel, was carried out on behalf of Anasuria Operating Company (AOC), the FPSO operator for the Teal, Teal South, and Guillemot A fields.
Teal P2 forms part of the Anasuria Cluster, which is centred on the Anasuria FPSO, approximately 190 kilometres east of Aberdeen in 89 metres of water.
The primary objective of the intervention was to perform a scale inhibitor treatment on the well, situated about four kilometres northeast of the FPSO.
This scale squeeze treatment is designed to safeguard production flow and maintain well integrity for at least the next three years.
The operation not only demonstrates Mermaid’s expanding capabilities in complex subsea operations but also highlights the company’s ability to interface seamlessly with multiple vendors.
For Anasuria Operating Company, the intervention supports the long-term production performance of the Teal asset and contributes to the UK’s energy security.
Scott Cormack, Regional Director for Mermaid Subsea Services (UK), commented: “This successful and efficient well intervention on Teal P2 highlights our expanding capabilities and ability to deliver complex subsea operations, be they in decommissioning or asset lifetime extension.
“To safely execute the project with a positive outcome on the primary objectives, while working with Anasuria Operating Company and multiple partners, reflects our commitment to operational excellence and supporting the UK’s long-term energy resilience.”
Tom Reeve, Wells Manager for AOC, added: “Mermaid, with AOC partners, have delivered a successful result on the Teal asset, helping to protect long-term production and build a relationship for future works.”
Mermaid Subsea kicked off its latest operational season in the North Sea in April, providing specialist support for well plug & abandonment (P&A) activities, as well as Inspection, Repair & Maintenance (IRM) campaigns.
For the second consecutive year, operations are being conducted using the Island Valiant, a proven and versatile subsea support vessel well-suited for the challenging conditions of the North Sea, following a charter agreement signed last year.
Despite a strong pipeline of work scheduled throughout 2025, Mermaid notes that there is still some vessel availability for additional projects.
The Island Valiant will soon be joined by Mermaid’s own dive vessel, which is expected to enter the North Sea market later this year.
Cormack concluded: “Mermaid is proud to continue supporting the energy sector in the North Sea and we’re excited that a new operational season is well underway.
“Our expertise in well decommissioning and asset integrity plays a vital role in safe, compliant, and cost-effective operations, and we look forward to working with clients new and old.
“The Island Valiant has been a reliable workhorse for us, and we’re excited to return with an expert crew, toolkit and solutions that are changing the way the basin operates.”
