Lucius (KC875) - Anadarko

Lucius Oil Field Profile

Location and Geology

• The Lucius Oil Field is located in the Gulf of Mexico, specifically in the Keathley Canyon blocks 874, 875, 918, and 919. It is situated in ultra-deepwater, with a water depth of approximately 7,100 to 7,386 feet.
• The field was discovered in December 2009 using the Ensco 8500 semi-submersible rig, which encountered high-quality crude oil (29º API) in subsalt Pliocene and Miocene sands.

Operator and Partners

• The field is operated by Anadarko Petroleum, which is now a subsidiary of Occidental Petroleum Corp.
• The partners in the project include:
  • Freeport McMoRan (approximately 25.123% working interest)
  • Exxon Mobil (approximately 20.94% working interest)
  • Petroleo Brasileiro (Petrobras) (approximately 11.5% working interest)
  • Eni Petroleum (approximately 8.5% working interest)
  • Inpex (approximately 10.107% working interest).

Field Development

• The development of the Lucius field was approved by Anadarko and its partners in December 2011. The project involves six subsea production wells tied back to a truss spar floating production facility.
• The truss spar is 605 feet long and 110 feet in diameter, with a hull weighing 23,000 tons. It is installed in approximately 7,100 feet of water and has a processing capacity of 80,000 barrels of oil per day (BOPD) and 450 million cubic feet of natural gas per day (mcf/d).

Production and Reserves

• The Lucius field began producing oil in January 2015.
• The field is estimated to contain more than 300 million barrels of oil equivalent (boe) reserves. As of the latest data, the field has recovered approximately 68.77% of its total recoverable reserves, with peak production achieved in 2016. Production is expected to continue until the field reaches its economic limit in 2044.

Infrastructure and Export

• The oil produced is transported via the Sekco Oil Pipeline to the Poseidon Oil Pipeline and then to shore. Associated gas is transported on the Discovery Gas Pipeline System.
• The oil is exported to the South Marsh Island (SMI) Area Block 205 Platform through an 18-inch diameter pipeline laid in three sections.

Contractors and Key Roles

• Technip: Responsible for the engineering, construction, and transport of the truss spar hull, as well as the installation of various subsea components such as flexible flowlines, gas lift jumpers, and umbilicals.
• Mustang: Provided topsides detailed engineering, procurement support, and equipment inspection for the truss spar floating production facility.
• FMC Technologies: Supplied five subsea production trees and two manifolds.
• Aker Solutions: Managed the project, designed, engineered, and manufactured the electro/hydraulic and gas lift umbilicals, and other associated equipment.
• First Subsea: Provided the Lucius Spar Mooring Connector.

Hub-and-Spoke Development

• The Lucius platform is designed to act as a hub for satellite fields, including the Hadrian South Gas Field. It accommodates two subsea well tiebacks from the Hadrian South field, which is located eight miles to the southeast.

History

• 2009: The Lucius field was discovered in December.
• 2010: Anadarko assembled a team to evaluate development options.
• 2011: A unitization agreement was finalized, enabling development to proceed. Technip and Mustang were awarded contracts for the spar and topsides, respectively.
• 2011: Anadarko sanctioned the project.
• 2012: Active drilling began.
• 2014: All six initial production wells were completed.
• 2015: First oil production started in January.

The Lucius project is a significant deepwater development in the Gulf of Mexico, showcasing advanced engineering and operational capabilities in ultra-deepwater environments.
