Production boosted at two North Sea fields

Production has been boosted from two North Sea fields following successful drilling campaigns.

First gas from the new C6 well at Spirit Energy’s Chiswick field in the Southern North Sea was achieved on 11 March 2020 and has added up to an additional 15 million ft3/d of gas to the field.

The Chiswick field, around 75 miles off the coast of Norfolk, has been producing gas since 2007. The new well brings overall production from the Greater Markham Area (GMA) to 110 million ft3/d of gas – enough to heat nearly 950 000 homes.

The development well, completed two months ahead of schedule, is expected to help extend life of the GMA hub to 2028.

Further, together with partner Dana Petroleum, Spirit Energy has completed drilling of a new production well at the Chestnut field, extending the life of that field by as much as three additional years. Initial expectation when the Chestnut field first came online more than a decade ago was for a little over two years’ production.

First oil from the new Chestnut well was achieved on 19 March 2020. Thanks to the £56 million investment from Spirit Energy and Dana Petroleum in the new well and a contract extension with Teekay Corp. for the Hummingbird Spirit FPSO, another 2.5 million bbl have been unlocked.

Neil McCulloch, Executive Vice-President Technical & Operated Assets, said: “The results from the new well at Chiswick exceeded our expectations and will provide us with valuable data to identify further drilling targets in the area. At the same time, the work our teams have done alongside our partner Dana Petroleum and our supply chain colleagues, notably Teekay Corporation and Altera Infrastructure, to maximise the potential of the Chestnut field has been exceptional and is making this field a notable success story.

“The industry faces unprecedented challenges but, taken together, the additional gas and oil from Chiswick and Chestnut provide a boost to production from two UK fields at a time when the secure supply of energy is critical.”
