Tailwind Energy has completed a development well for the Evelyn field in the North Sea.
Evelyn, designed as a tie-back to the Triton FPSO operated by Dana Petroleum, could yield 17.4million barrels of oil equivalent (boe), with an additional 4.4million from a second well.
Services firm Petrofac managed completion of the Evelyn development well on behalf of Tailwind, using the Stena Don rig.
Tailwind said the well successfully flowed at 10,000 barrels per day, in line with expectations.
It has now been left suspended in preparation for installation of subsea facilities and a pipeline next year.
Evelyn, which lies 110 miles east of Aberdeen, is expected to begin production in Q4 2022.
Tailwind is 100% owner of the project and holds a 46.42% stake in the Triton FPSO.
Regulators rubber-stamped the project earlier this year, which Tailwind bought in 2018 as part of the stakes of Shell and ExxonMobil in the Triston cluster.
Tailwind was founded in 2016 and is backed by private commodities and energy group Mercuria.
Alongside Evelyn, Tailwind is installing a second production pipeline for the Gannet E field, also producing via Triton, which has been constrained due to the flowline’s size.
Earlier this year Tailwind acquired BP’s 27.5% stake in the Shell-operated Shearwater hub in the central North Sea.
In June, chief executive Steve Edwards said said the recent acquisitions and organic growth projects should move the firm to the “next level” of very strong cash flow.
