DRILLING & PRODUCTION — Quick Takes
Fixed platform eyed for field offshore Norway
Statoil proposes to develop Dagny oil and gas field in the Sleipner area of the Norwegian North Sea with a fixed platform and nearby Eirin gas field from the seabed. Dagny was discovered in 1974, Eirin in 1978.
Dagny field oil occurs in the Upper Jurassic Hugin formation at about 3,500 m. The field lies in 120 m of water 30 km north of the Sleipner A platform.
Statoil said recent appraisal drilling established connection between western and eastern parts of the field. The eastern structure is called Ermintrude.
Eirin is about 9 km north of the Dagny discovery well. Most of its gas is in the Upper Triassic Skagerrak formation at a depth of about 4,120 m, according to the Norwegian Petroleum Directorate.
Statoil said subsea Eirin wells will be tied back to the planned Dagny platform. Gas from the Dagny platform will flow through a tieback to Sleipner East field.
The company proposes to load oil onto shuttle tankers from the Dagny platform.
It estimates ultimate production from Dagny and Eirin at 300 million boe.
Statoil, which operates the fields with 58.5% interests, said it will make an investment decision in a year. It envisions the start of production in 2016.
Other provisional interests, subject to negotiation before the development decision, are ExxonMobil Exploration & Production Norway AS 33%, Total 6.5%, and Det Norske 2%.
Fletcher Finucane oil field project gets FID
Santos Ltd. said its $490 million Fletcher Finucane oil field offshore Western Australia has received a final investment decision.
The project, which lies on permit WA-191-P, will be developed through three subsea wells tied back to a Santos-operated floating production, storage, and offloading vessel at Mutineer Exeter field.
Initial gross production is expected to be 15,000 b/d of oil from second-half 2013.
Santos reached FID after buying out Tap Oil’s 8.2% interest in the project for $21.7 million (Aus.).
Tap later said it could not generate sufficient revenue from the sale of oil processed at Mutineer Exeter to warrant the new expenditure.
Anadarko lets Lucius subsea contract to FMC
A group led by Anadarko Petroleum Corp. let a contract to FMC Technologies Inc. to provide subsea systems and services for the deepwater Gulf of Mexico Lucius oil and gas project off Texas.
FMC will provide five subsea production trees and two manifolds for Lucius field on Keathley Canyon Block 875 in 7,100 ft of water.
The Lucius unit, about 275 miles southeast of Galveston, Tex., includes parts of Keathley Canyon Blocks 874, 875, 918, and 919. Anadarko, which operates the unit with a 35% working interest, drilled the discovery well in 2009 (OGJ Online, Dec. 15, 2011).
Subsea system deliveries are scheduled to start in the fourth quarter, FMC said.
Lucius development plans call for using a truss spar with a capacity of 80,000 b/d of oil and 450 MMcfd of gas starting in 2014.
Other participants in the Lucius unit include Plains Exploration & Production Co. 23.3%, ExxonMobil Corp. 15%, Apache Deepwater LLC 11.7%, Petroleo Brasileiro SA 9.6%, and Eni SPA 5.4%.
