Hewett

Hewett is a gas field in the southern North Sea, operated by ENI UK Limited. It was discovered in 1966 and produced from 1969 to 2023. Production has ceased. From May 1983, when its monthly records begin, it produced about 119 billion cubic metres of gas.

Production

Hewett produced about 3.3 million barrels of oil and condensate and 119 billion cubic metres of gas between May 1983 and April 2023. The NSTA's monthly records for the field begin in May 1983, but it started producing in July 1969, so earlier output isn't included.
