Heidelberg is located in 5,300 ft (1,615 m) of water and has 200-400 MMbbl of recoverable resources.
Development consists of a truss spar with a capacity of more than 80,000 b/d of oil and 2.3 MMcm/d (81 MMcf/d) of natural gas, six production wells, two drill centers, dual looped 8-in. flowlines, and 16-in. oil and gas export lines.
According to the operator, the Heidelberg truss spar is 605 ft (184 m) in length, 110 ft (33.5 m) in diameter, a topsides operating weight of 16,000 tons, and a hull weight of 23,000 tons.
This is Anadarko’s second major truss spar development in the deepwater Gulf of Mexico in the last two years. The company implemented its “Design one, build two” approach to the field development by constructing a replica of the Lucius spar.
Anadarko holds 31.5% along with partners Cobalt (9.375%), Eni (12.5%), ExxonMobil (9.375%), Freeport McMoran (12.5%), Marubeni (12.75%), and Statoil (12.0%).
