Lucius: Deepwater Gulf of Mexico

image

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.

USA: BP Sells Stake in Pompano and Mica Offshore Fields to Stone Energy

BP revealed on Friday the agreement to sell its interests in the Pompano and Mica fields in the deepwater Gulf of Mexico to Stone Energy Offshore, LLC, a subsidiary of Stone Energy Corp. for $204 million in cash.

The agreement includes the sale of BP’s 75 per cent operated working interest (WI) in the Pompano field and assets and 50 per cent non-operated WI in the Mica field, together with a 51 per cent operated WI in Mississippi Canyon block 29 and interests in certain leases located near the Pompano field.

Completion of the sale is subject to the pre-emption rights of various co-working interest owners. The companies expect to complete the sale in 2012.

BP group chief executive Bob Dudley said: “We continue to make progress in our divestment programme as we focus on BP’s areas of strength around the world. The sale of these mature assets will allow us to concentrate our efforts on the major production hubs and significant growth opportunities that BP has in the Gulf of Mexico.”

On completion of the transaction BP will continue to operate seven production platforms in the Gulf of Mexico, producing from some of the largest deepwater oil and gas fields ever discovered. Among BP’s Gulf of Mexico assets are the giant fields Thunder Horse, Atlantis and Mad Dog, each of which have long production profiles and development programs.

The Pompano Field is eight miles long, located within water depths ranging from 1,100 feet to 2,200 feet. Given the distance and depth range, the Pompano owners elected to use proven technology and placed a fixed platform in shallow water at the northern end of the field.

Both the Pompano and Mica fields produce oil and gas through the Pompano platform, approximately 120 miles southeast of New Orleans. First oil was produced from the Pompano field in October 1994 after being discovered by BP and Kerr-McGee in 1985. The Mica field, tied back to the Pompano platform some 29 miles to the north west, began production in 2001.
