Oil production has commenced at the Lucius field, located in the Keathley Canyon block in the Gulf of Mexico.

The oil field’s spar, which is located 240 miles south of the Louisiana coast, US, in approximately 7,000ft of water, has a design capacity of 80,000 barrels of oil per day (bopd) and 450 million standard cubic feet per day (MMscfd) of gas.

"Oil produced by the Lucius spar will be exported to the South Marsh Island (SMI) Area Block 205 Platform by an 18in-diameter pipeline."

Six subsea wells were tied back to a moored production-handling spar linked to shore via oil and gas pipelines.

Anadarko Petroleum operates the field with a 23.8% working interest, while Eni holds an 8.5% working interest.

Freeport and ExxonMobil own 25.1% and 23.3% stakes, respectively, while Petrobras has an 11.5% interest and INPEX holds a 7.75% stake.

The Lucius field was discovered in November 2009 and the subsequent development project was approved in late 2011.

Oil produced by the Lucius spar will be exported to the South Marsh Island (SMI) Area Block 205 Platform by an 18in-diameter pipeline, which was laid in three sections by Cronus Technology.

The Lucius project co-venturers signed an agreement with the Hadrian South field partners in 2011.

The agreement allows natural gas produced from the Hadrian South field to be processed at the Lucius processing facility.
