Tailwind starts production from North Sea Evelyn project

Offshore staff

LONDON – Tailwind Energy has delivered first hydrocarbons from the Evelyn tieback project in the UK central North Sea.

Dana Petroleum (E&P) and TechnipFMC managed the subsea execution phase, under which the 2021-drilled EV-01z horizontal development well was tied back to the Triton FPSO via a subsea production line and an umbilical services line.

In addition, Dana managed the Triton topsides modifications on Tailwind’s behalf.

Evelyn, in licence P.1792 (block 21/30), was discovered in 1984. Tailwind acquired the field from Shell in 2018 as part of a package of assets in the Greater Triton Area in 2018, securing approval or its Field Development Plan in early 2021.

The field’s well fluids are exported via the FPSO, 6 km to the north-east, in which Tailwind has 46.42% equity.

As part of the same subsea campaign, the project team installed a second subsea production line from Tailwind’s Gannet-E field, which already produces via Triton. The flowline was commissioned and brought into production earlier this week.

It allows for increased production rates from the existing three Gannet E wells, and debottlenecking for a fourth Gannet E well. This should be drilled in Q4 and brought into production via the new line in Q1 2023.

Evelyn and the Gannet-E expansion projects should add over 10,000 boe/d to Tailwind’s net production.

Recently the company also completed a workover of the Orlando 3/03b-13Y well and resumption of production from the Orlando field in the UK northern North Sea.

Petrofac served as project manager and well operator for the workover, using the Island Innovator Rig with support from CNR International (U.K.), operator of the host Ninian Central platform. Following commissioning of new equipment and a clean-up flow period the well has been producing more than 5,000 b/d of oil.
