A successful appraisal well reached TD in early 2011, and a well test was performed on the discovery well in May 2011.ĭelineation and testing showed the Lucius Field had thick pay zones consolidated in a relatively compact area. The discovery well was drilled to a total depth of 20,000 feet by the ENSCO 8500 drill ship in late 2009, penetrating a 200-foot subsalt Pliocene oil column. The recommendations primarily enhance compliance efforts with Safety and Environmental Management Systems (SEMS) regulations, the predictability of equipment delivery for fabricating topsides, and managing offshore hookup and commissioning efforts.įigure 2 shows a simplified geological interpretation of the Lucius Field. Based on Anadarko’s experience on Lucius, several staffing and organizational changes were recommended for future major projects, including Heidelberg. The ability to successfully execute a project as large and complex as Lucius on a fast-track timeline can be credited largely to Anadarko’s development strategy of utilizing a core group of proven, trusted suppliers, and to close cooperation between the Lucius and Hadrian South project teams. The 300 MMcf/d tieback was executed in parallel with the Lucius development, and achieved first production in March 2015. It was designed not only to accommodate the initial six wet-tree Lucius oil wells in the southeast corner of Keathley Canyon, but also to host two subsea well tiebacks from ExxonMobil Development Co.’s Hadrian South natural gas field, located eight miles to the southeast in 7,500 feet of water at Keathley Canyon 964 (ExxonMobil’s deepest subsea tieback).
ExxonMobil, Plains Offshore Operators/PXP Offshore, Petrobras, Eni and Teikoku (Inpex) are partners on Lucius and Eni, ExxonMobil, Marubeni Oil & Gas, Freeport-McMoRan, Statoil and Cobalt International Energy are partners on Heidelberg.Īn additional strategic consideration at Lucius was implementing a hub-and-spoke development philosophy–the first spar host facility built by Anadarko since 2006. Anadarko is operator of both projects (Figure 1). Lucius (Keathley Canyon 874, 875, 918 and 919) is estimated to contain more than 300 million barrels of recoverable oil-equivalent reserves, while Heidelberg (Green Canyon 859, 860, 903, 904 and 948) holds an estimated 200 million-400 million boe of recoverable resources. In addition, Anadarko reduced the number of engineering man-hours for Heidelberg’s hull and topsides by 17 and 24 percent, respectively, and the fabrication man-hours by 16 and 17 percent, compared with its Lucius twin. In fact, Anadarko was able to move from concept selection to cutting first steel for Heidelberg spar’s hull within six months, and from concept selection to cutting first steel on the topsides in only 12 months. The synergies and efficiencies created by this strategy helped Anadarko produce first oil at Heidelberg–the first field development to replicate the Lucius spar design–ahead of schedule and under budget. The benefits of using the same standard design for multiple projects include less time to sanctioning, reduced engineering charges, expedited order placement, ease of contracting, certainty of design and scheduling, and enabling the exchange of parts, personnel, equipment, etc. The Lucius spar design was meant to be flexible. Lucius was brought online just over three years after project sanctioning, and Heidelberg achieved first oil only 32 months after sanctioning. The Heidelberg spar is in 5,300 feet of water at Green Canyon 859 and has a capacity of 80,000 bbl/d and 80 MMcf/d. Stationed in 7,000 feet of water at Keathley Canyon 875, the Lucius spar has a daily capacity of 80,000 barrels of oil and 450 million cubic feet of gas. The look-alike spars are both 110 feet in diameter and 605 feet long, with hulls weighing 23,000 tons.
One year later and some 100 miles to the northeast, production commenced significantly ahead of schedule on a “sister” truss spar at the Heidelberg Field. and its partners achieved first oil on a newly installed truss spar at the deepwater Gulf of Mexico Lucius Field on Jan.
