Project Profile
Value: Undisclosed
Location: Canyon block 608, 160 miles south of New Orleans, USA
Start-up Year: March 2004
Production: 50,000 barrels of oil and 150 million ft³ of gas per day
Water depth: 4,300 ft
The Marco Polo field is located in Green Canyon block 608, 160 miles south of New Orleans. It is fully owned and operated by Anadarko Petroleum. The field was discovered in April 2000 and lies in water 4,300ft deep.
It produced its first oil in March 2004. The field is drained by six delineation wells with an average net pay of 292ft. It produces approximately 50,000 barrels of oil and 150 million ft³ of gas per day. The field is being developed by the world\'s deepest water Tension Leg Platform (TLP) which is owned by Deepwater Gateway, a 50/50 joint venture company between GulfTerra Energy Partners and Cal Dive International. This Moses TLP is designed by MODEC International and Sea Engineering. The hull was fabricated at the Samsung Heavy Industries Yard SHI Koji Island, South Korea. The first steel was cut in July 2002 and it was loaded out in June 2003. The hull travelled 13,000 miles and arrived in Texas in August 2003. It was installed that November 2003. The hull supports topsides over three deck levels. Designed by Alliance Engineering and constructed in Corpus Christi, it weighs 6,300t (lift weight) or 7,250t (operating weight). It can accommodate 26 people in its quarters. The processing capacity is 120,000 barrels of oil and 300 million ft³ of gas per day. The K2 field, located on Green Canyon Block 518 in the Gulf of Mexico, will also be tied back to the Marco Polo platform.
Pipelines:
The oil and gas are exported by a pipeline system owned by GulfTerra. The gas pipeline extends approximately 75 miles from Green Canyon 608 to Green Canyon 236 (with a water depth of 1,750ft). There is a subsea interconnect with the GulfTerra-owned Typhoon gas pipeline, where the two form the Anaconda Gathering System. The capacity of Anaconda is 320 million ft³ of gas, expandable to 430 million ft³. The oil pipeline runs approximately 36 miles to Green Canyon 164 (where the water depth is 2,800ft). The 12.75in steel catenary riser and 14in pipeline leads to the subsea interconnect with the GulfTerra-owned Allegheny oil pipeline. This has a capacity of 120,000 barrrels/day of oil. It then connects with the Poseidon Oil Pipeline system (36% owned and operated by GulfTerra) and the Cameron Highway Oil Pipeline System (50% owned and operated by GulfTerra) on the Ship Shoal 332 platform.
