EnQuest reports that first oil has been delivered Nov. 21 from the Scolty/Crathes development in the U.K. North Sea ahead of schedule and under budget.

“Unit operating costs are expected to be under $15/bbl in the initial peak volume years and production is anticipated to continue until 2025,” EnQuest CEO Amjad Bseisu said in a news release.

The Scolty and Crathes fields are estimated to hold up to 15 million barrels of oil reserves. The development plan for the fields consists of two single horizontal wells tied back over via subsea pipeline 25km in a ‘daisy chain’ fashion to the Kittiwake platform in the Greater Kittiwake Area, the release said. Oil from Scolty and Crathes will be exported via the Forties Pipeline System.

EnQuest said Scolty/Crathes represents a key component in its hub model for Kittiwake and extends the economic life of the Greater Kittiwake Area into the next decade.

EnQuest holds a 50% interest, with MOL Growest (II) Ltd. holding 50%
