Integrated oil and gas engineering at Wytch farm

WSP has worked closely with the operator of Wytch Farm since 2011, when the value for money and one-team approach we offered saw us awarded a framework agreement to provide vital design engineering and construction management services. Our expertise supports production at Western Europe’s largest onshore oil and gas field – with our role ranging from providing expertise in key disciplines to undertaking full multidisciplinary projects.

For nearly a decade, WSP has supported PUK WYF on projects – both large and small – at the well sites and gathering station in its Wytch Farm field in Dorset and its facilities at the Hamble Terminal in Hampshire. The Wytch Farm site is located in a Site of Special Scientific Interest (SSSI) area within Dorset and close relationships with various stakeholders are key to maintaining the operation.

Wytch Farm is a land-based oil well site producing approximately 14,000 barrels of oil equivalent and approximately 350,000 barrels of water each day. Output from the wells is delivered to a main gathering station, which stabilises the crude oil by first-stage separation of oil, gas and water – with the water processed and injected back into the reservoir. The other elements are then exported via a dedicated 91 km pipeline to the Hamble Terminal.

One-team working

We have forged a close relationship with PUK WYF and are trusted for the expertise and value for money we offer. This has seen teams of up to 20 WSP specialists integrate with our client’s team, sharing resources and working on site during the construction phase of projects. Developing a one-team approach with common goals and culture has resulted in high-quality engineering and design and has also embedded a new approach to teamwork. 

The industry team in our Birmingham office has the multidisciplinary engineering, project management and construction management expertise we need to provide clients such as PUK WYF with a turnkey package. We are also able to call on specialists across WSP with expertise in areas such as environmental consulting, and to act as independent HAZOP chair on projects.

Strong track record

Highlights of our work with PUK WYF include:

• Reinstating the decommissioned Furzebrook Rail terminal, which sits within a Site of Special Scientific Interest (SSSI), back to the original ecosystem – including crushing and removing 4,000 tonnes of concrete

• Replacing two sections of underground water-injection pipelines at Wytch Farm, with a specialist contractor for the horizontal directional drilling. This included the pipeline crossing under the water in Poole Harbour between mainland Dorset and Furzey Island. 

• At the Hamble Terminal, designing and managing the overhaul and replacement of pipework, export valves, crude oil tanks, export pumps and spools

• Delivering the complex re-investment at L Site, which is a Well Site facility on the Furzey Island Site of Special Scientific Interest successfully despite an expansion of the project scope

“There were quite a lot of complicated operational and contractual interfaces to manage, which were quite difficult at times, but with the end objective in mind these were all suitably resolved, and the team performed very well.” 

Trevor Keep – Engineering and Maintenance Services Manager, Perenco

• Designing the new well infrastructure for the high-level production M Site, for which we minimised downtime by phased installation and installing headers on pipetrack during work on adjacent wells

• Upgrading the dormant Wareham D Site by reinstating Well WS-01 – a Bridport reservoir producer – using a beam pump and decommissioning redundant equipment

• In 2011, we managed engineering and construction for a major pre-planned shutdown (TAR) – ensuring all work was completed with no lost-time accidents.

This in-depth experience enables us to undertake a variety of projects for our client, with each new piece of work strengthening our relationship.
