Neptune Energy and its partner Spirit Energy have started production from the tenth well at the Cygnus gas field in the UK North Sea.

The well has been drilled using Borr Drilling’s Prospector 1 jack-up rig.

Neptune Energy operates the Cygnus field, which has one of the lowest carbon intensities on the UK Continental Shelf (UKCS) at approximately 4kg of CO₂ per barrel of oil equivalent, as of December 2022.

The remaining 61.25% interest is held by Spirit Energy.

Upon completion of the tenth well, the Cygnus gas facility will have the capacity to produce enough gas to meet the needs of approximately two million households in the UK.

Neptune Energy UK country director Alan Muirhead said: “Bringing the tenth Cygnus well online is an important milestone for the field and supports additional supplies of lower carbon gas for UK homes and businesses.

“Domestic production has a crucial role to play in supporting energy security in this country, and Neptune has increased gas supplies to the UK from our operated assets in the UK and Norwegian North Seas.”

Neptune said it has started drilling the 11th well in the Cygnus field, which is planned to start production in the second quarter of 2023.

The Cygnus field is in the Southern North Sea in blocks 44/11a and 44/12a, approximately 12km north of the Munro Field and 15km northwest of the Tyne Field.

Last month, Neptune Energy commenced production from its Rӧmerberg 6 well, which is the ninth well in the Römerberg oil field, located in the Rhine Valley, south-western Germany.
