Earlier this month, the first gas from the new C6 well at Spirit Energy’s Chiswick field in the Southern North Sea was achieved. This has added up to an additional 15 million standard cubic feet of gas per day to the field.
The Chiswick field is located around 75 miles from the coast of Norfolk, and has been a gas producer since 2007. This new well brings overall production from the Greater Markham Area (GMA) to 110 million standard cubic feet of gas per day, which is said to be enough to heat almost 950,000 homes.
The development well was completed two months ahead of schedule, and is expected to help extend life of the GMA hub to 2028.
Together with Dana Petroleum, Spirit Energy has also completed drilling of a new production well at the Chestnut field. When the Chestnut field first came online more than a decade ago, a two years’ production was expected, while the results from the new well indicates an extension of three additional years. First oil from the new Chestnut well was achieved on 19 March 2020.
Spirit Energy and Dana Petroleum invested £56 million in the new well and another 2.5 million barrels have been unlocked.
According to Neil McCulloch, Executive Vice-President Technical & Operated Assets, “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.”
McCulloch also states that “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.”
