UK independent EnQuest has brought its Scolty and Crathes development in the UK North Sea onstream.
The firm also confirmed sailaway of the US$2.6 billion Kraken development floating production, storage and offloading vessel is due in coming days, with first oil scheduled for 1H 2017.
Scolty was discovered in 2007 by Lundin and Crathes in 2011 by EnQuest. The development consists of two single horizontal wells tied back over via subsea pipeline 25km in a "daisy chain" fashion to the Kittiwake host facility. Oil from Scolty and Crathes will be exported via the Forties Pipeline System.
EnQuest says first oil from the development was ahead of schedule and under budget, about a year after the field development plan was approved and the project sanctioned.
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 says the development was the only offshore pure oil field development plan approval in the UK North Sea in 2015.
Kraken
EnQuest says, following good progress on commissioning the water systems, the Armada Kraken FPSO, vessel operator Bumi Armada's first in the North Sea, is expected to sail away in the coming days, from a deep water anchorage off the coast of Singapore. The journey to the North Sea should complete around mid-January 2017.
The Kraken development project remains on course to deliver first oil in H1 2017. It will comprise 25 wells: 14 for production and 11 for injection.
Kraken is a large heavy oil accumulation in the UK North Sea, in the East Shetland basin, to the west of the North Viking Graben; about 125km east of the Shetland Islands. The field is spread over 42km at a depth of 1300m below sea level, and is expected to hold 147 MMbbl of heavy crude oil, at about 14 API in the 2P probable reserves category.
It is one of the largest current development projects in the UK North Sea and has an up to 25-year anticipated production life.
