ABERDEEN, UKSpirit Energy has found more gas at the Grove field in the UK southern North Sea.

The Grove North East development well (49/10a-G7) on an unappraised and undrained area of the field, drilled by the jackup Maersk Resolve, encountered around 250 ft (76 m) of gas-bearing B & C sandstones in the Carboniferous.

Reservoir quality, sand thickness, and gas column height were all within pre-drill expectations, and the well was completed with production starting yesterday.

Girish Kabra, Spirit Energy’s director for North Sea operated assets, said: “The commercial discovery is important for Grove as it opens up future growth opportunities in and around the license blocks.”

The discovery also looks set to prolong the field’s life from 2022 to at least 2028, he added. Spirit plans to update volumes after the well has been onstream for a while and production data have been gathered and analyzed. “The project was sanctioned in a relatively low gas price environment in 2020 to support the supply chain activities through the COVID pandemic,” Kabra said.

“Drilling was made possible by efforts of our team and supply chain partners to reduce drilling costs and through the re-use of facilities, which also contributed to lowering the carbon intensity.

“The Grove well demonstrates ability to deliver life extension opportunities in the North Sea basin, as we did with the Chestnut and York fields.”

Grove is close to the UK-Netherlands median line. Its gas is processed at the Markham J6-A facilities, also operated by Spirit, and transported via the West Gas Transport pipeline system to the Den Helder terminal in the Netherlands for further processing.
