LONDON  TotalEnergies E&P UK and its partners should sanction the Glendronach gas development west of Shetland by year-end 2022.

According to Kistos, which farmed into the surrounding Greater Laggan Area (GLA) earlier this year, Glendronach should be onstream and producing through the GLA offshore pipeline system before the end of 2024.

The partners also plan an exploration well on the 638-cf Benriach prospect, which is close to the producing infrastructure.

As for Kistos’ E&P operations in the Dutch North Sea, the company has decided to continue exporting gas from Q10-A (Kistos 60%) via the P15-D platform, after considering various rerouting options. This should limit the future capex and the associated risk of interruptions to production that would have arisen.

Preparations are underway for a new work program to slow Q10-A’s production decline, with negotiations progressing for a rig to start work in first-quarter 2023. The schedule will include installation of velocity strings in the A-06 and A-05 wells, a sidetrack of the A-01 well into the Slochteren Formation and simulation of the Zechstein clastic formation in the A-04 well.

Estimated gross cost is about €30 million (US$29.7 million).

The Concept Assess phase has concluded for the Orion oil development, with three options under review. Two of these would make use of the Q10-A platform, while the third would involve installation of a new, minimal facilities Bridge Linked Platform alongside.

Orion’s oil is located directly above the Q10-A gas field in the Vlieland sandstone formation, a proven play in the area, although this reservoir has low porosity and permeability. However, it also contains natural fractures that could enhance productivity, as demonstrated by an appraisal well last summer that flow tested 3,200 bbl/d from an 825-m horizontal section.

As for the Q11-B appraisal well, which was suspended in February, Kistos is considering development options, in light of current gas prices.

The Dutch authorities have rejected the company’s application for an extension of its operated M10a and M11 licenses north of the Wadden Islands beyond June 30, 2022. Kistos has lodged an appeal and will submit the full details of its reasons for doing so by the deadline of Sept. 14, accompanied by a draft field development plan. It expects the appeal to be heard before the end of the year.
