Spirit Energy finds more gas at UK North Sea’s Grove field

 

Spirit Energy has found more gas at the Grove field in the UK North Sea following the drilling of the Grove North East development well (49/10a-G7).

The successful drilling of the infill well enables the company to extend the life of the Grove gas field from 2022 to at least 2028. The offshore field, which is located near the UK–Netherlands median line, has been producing since 2007.

According to Spirit Energy, the Grove North East development well intersected carboniferous reservoir units at the target depth and proved the presence of nearly 250ft gas-bearing B and C sandstones.

The company said that the reservoir quality, sand thickness, as well as the height of the gas column are within the pre-drill expectations. The well was completed for production and has achieved first gas.

Furthermore, the production is in line with subsurface prognosis and pre-drill estimates, said Spirit Energy’s North Sea-operated assets director Girish Kabra.

Kabra said that the commercial discovery is significant for the Grove field as it paves the way for future growth opportunities in and around the licence blocks.

The Grove North East development well was drilled by the Maersk Resolve jack-up rig from Maersk Drilling. Targeting an un-appraised north-eastern limb of the field, the development well could potentially provide 4.2 million barrels of oil equivalent (mmboe) net additional reserves.

Kabra said: “The project was sanctioned in a relatively low gas price environment in 2020 to support the supply chain activities through the Covid pandemic.

“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.”

Spirit Energy has an operating stake of 92.5% in the Grove field and is partnered by RockRose, which holds the remaining stake of 7.5%.

The gas drawn from the Grove field is sent to the Spirit Energy-operated Markham J6-A facilities for processing. It is subsequently transported through the West Gas Transport pipeline system to the Den Helder terminal in the Netherlands, where it is further processed.
