The Arthur Field, in Block 53/02, is located about 30 miles east of Bacton, Norfolk, in approximately 140 feet of water. It was discovered in October 2003. The field is a subsea development tied back to the existing ExxonMobil-operated Thames platform by a new 20-mile, 12-inch pipeline and umbilical. The produced gas is exported via the existing pipeline to the Bacton terminal. The project is expected to produce at gross rates of up to 110 million cubic feet per day with an ultimate recovery estimated at 130 billion cubic feet (gross).
Robert Olsen, chairman, ExxonMobil International Limited, said, "We are delighted to have been able to bring the field into production in just over a year using subsea technology and optimising existing infrastructure to capture reserves faster and at lower unit development costs."
The field may ultimately comprise up to three development wells connected to the Arthur manifold via 8-inch pipelines and umbilicals. The Arthur 2 well is to be spudded in the near future and a potential third well may be drilled later in 2005.
MNSL is the operator of the field with 70 percent interest. Co-venturer EOG Resources United Kingdom Limited, a subsidiary of EOG Resources, Inc., holds the remaining 30 percent. ExxonMobil is one of the largest producers of oil and gas in the UK, with interests in some 90 fields. In the northern North Sea, ExxonMobil operates the Beryl area complex and the SAGE gas system and terminal at St. Fergus. In the southern North Sea, in addition to its operatorship of the Arthur field and Thames complex, ExxonMobil also operates the Camelot, Lancelot, Guinevere, Excalibur, Galahad and Malory fields.
