King Subsea Development
King is located in Mississippi Canyon Block 764 in the Gulf of Mexico about 140 miles southeast of New Orleans in 3,285 feet of water. The lease was acquired by ARCO in OCS Lease Sale 110 in April 1987.
Shell Deepwater Development Inc. was the development operator and has a 33.3% interest in the project. BP has a 66.7% interest and is the production operator.The discovery well was drilled in 1998 by Vastar, using Diamond Offshore's Ocean Victory drilling rig. The discovery well and a sidetrack were drilled and temporarily suspended. The exploratory well was completed as a subsea producer and tied back to the Mars tension leg platform.
The target reserves are in four zones ranging in depths from 15,400 to 19,200 feet, subsea.The reserves are primarily oil, with an oil to gas ratio of 80:20, based on barrel equivalent basis.
Development The partners developed King utilizing a subsea system tied back approximately 3.2 miles to the Mars TLP on Mississippi Canyon Block 807 in 2,940 feet of water.
Initially, the development consisted of one subsea well tied-back via two flowlines to the existing subsea infrastructure for the Mars subsea well located in Mississippi Canyon Block 807. From that point, the Mars subsea well and the King subsea well share a pair of flowlines and umbilical that are tied back to the Mars TLP. Additional wells may be tied into the proposed system in the future.
