Current discoveries in the Gulf of Mexico combine extreme water depths with high pressure/high temperature (HPHT) reservoir conditions where mudline shut in pressures can approach or even exceed 15 ksi. Given the limits of current drilling and completion design, the offshore industry must now seek alternative solutions. From an economical standpoint, the longer times needed to drill and complete such wells combined with ever increasing MODU rig day rates has put greater emphasis on dry tree technology as an enabler of new developments. BP recently initiated the design and qualification of a 15K dual barrier dry tree riser system capable of installation in water depths up to 10,000 ft (3,048 m). While trial casing runs have been delivered in sizes applicable for the system, T&C riser connectors must be designed and qualified for the fatigue service and high pressures of these environments.
