Kerr-McGee Constitution


U.S., Gulf of Mexico Block GC 680

Landmark: Truss spar

Constitution, located on Green Canyon Block 680, was sanctioned in January 2004. The Constitution truss spar called the Global Producer X, will be located in a prime position to provide a strategic hub for third-party business in Ticonderoga on Green Canyon Block 768. The spar has a daily production capacity of 70,000 barrels of oil and 200 million cubic feet of gas. This new spar is 554 ft (169 m) long and 98 ft (30 m) in diameter, which is similar to Kerr-McGee's Gunnison truss spar.

Two subsea wells from Ticonderoga are tied back to the Constitution spar.
