U.S., Gulf of Mexico Block MC 765
Landmark: The Shell Princess is Shell’s first 15,000 psi subsea system.
The Princess discovery is located in Mississippi Canyon Block 765 in 3,610 ft (1,100 m) of water about 140 miles (230 km) southeast of New Orleans. The field, which is adjacent to the Ursa Field, was discovered in 2000. Because of its proximity to Ursa, petroleum liquids and natural gas produced from Princess are processed and transported via the Ursa infrastructure already in place. Total gross recovery, including Ursa’s A10 well, is estimated to be approximately 175 mmboe.
The Princess field is a subsalt accumulation with five commercial pay sands. The development uses 15,000 psi subsea equipment, which is a first for Shell’s operated subsea developments. The project features a BOP-ontree intervention system, a first for vertical trees. Princess’ initial phase of development consists of one tensionleg platform well (Ursa A10) and three well subsea systems, which utilizes dual-insulated flowlines with production sleds and a steel tube umbilical with a termination skid. The subsea system is expandable to serve up to four wells.
Production from Princess’ initial phase of development is transported less than four miles (six km) to Shell’s Ursa platform via dual eight-inch insulated flowlines. All Ursa production is sent via an 18"-diameter oil pipeline and a 20"-diameter natural gas pipeline to Shell’s West Delta 143 gathering platform 47 miles (75 km) away.
