Lucius: Deepwater Gulf of Mexico


Located in the deepwater Gulf of Mexico on Keathley Canyon Blocks 874, 875, 918 and 919 (Lease OCS-G-21444) in a water depth of 7,126 feet (2,172 meters) is the Lucius oil and gas field. Acquired by Anadarko, formerly Kerr-McGee, at the Western GOM Lease Sale No. 174 in 2005, the company holds a 35% interest in the field. Co-owners in the discovery include Plains Exploration & Production PEP 23.33%; Anadarko 35%; ExxonMobil 15%; Petrobras 9.6%; and Eni 5.4%

A discovery was made at the Lucius prospect in December 2009. The discovery well encountered more than 200 feet (61 meters) of net pay in subsalt Pliocene and Miocene sands. Lucius was drilled to a total depth of about 20,000 feet (610 meters) by the ENSCO 8500 semisub.

A sidetrack appraisal well was then drilled in January 2010, encountering almost 600 net feet (183 meters) of high quality oil pay with additional gas-condensate pay in thick subsalt sands. Drilled as an up-dip sidetrack roughly 3,200 feet (975 meters) south of the discovery well, the appraisal well reached a total depth of 20,600 feet (6,279 meters) in 7,100 feet (2,165 meters) of water.

Field Development

Anadarko sanctioned the development on Dec. 15, 2011. The development plan calls for six producing wells connecting to a truss spar with a production capacity of 80,000 bopd and 450 MMcf/d of natural gas.
The spar is currently being constructed at Technip’s facility in Pori, Finland. Drilling will begin in 2012 with first production slated for 2014.
