The Finlaggan development targeting 30mmboe of gas condensate reserves from two subsea production wells tied back 20km to the Britannia platform, which is operated by ConocoPhillips.

In an update on Monday, Zennor said that both Finlaggan production wells (F1 and F2) have now been successfully drilled and cased to their target depths with long and highly productive lateral sections through the Lower Cretaceous reservoirs. The wells were drilled by Transocean’s Paul B Loyd Junior drilling rig.

“The results from both wells have been very encouraging with F1 demonstrating high quality hydrocarbon bearing sands in the northern extension of Finlaggan as prognosed, and F2 proving sand continuity over the previously interpreted fault between the southern two segments of the field. Zennor is delighted with the results achieved and the positive implications for reserves and productivity. Completion and clean-up operations across both wells are now underway and are expected to be finished during the current quarter,” the company added.

Apart from the operational update, Zennor said it had on March 28 2019, executed all major Finlaggan offtake agreements in line with previously agreed commercial terms.

“These agreements provide for the export of Finlaggan production through the Britannia facilities, the Forties Pipeline System, the SAGE Terminal and the SEGAL System,” Zennor said.

Martin Rowe, Zennor’s Managing Director, said: “The team has worked exceptionally hard over recent months and I am delighted to see those efforts come to fruition in achieving significant commercial and operational milestones. All aspects of the Finlaggan development project are firmly on track to deliver first production in Q4 2020 as planned and we greatly appreciate the support we continue to receive from our key contractors, partners, banking syndicate, the OGA and our shareholders.”

As previously reported, the subsea construction contract has been awarded to TechnipFMC, with the main installation works planned for 2019. This includes the laying of a 10” pipe-in-pipe production flowline and electrohydraulic control umbilical back to ConocoPhillips’ Britannia platform.
