Technology Focus Even in today's changing times, the challenges of deep water continue to demand new and innovative technologies. Explorers are finding new fields hidden tens of thousands of feet below the mudline, reaching depths that cannot be completed currently. To produce from these depths, companies are developing completion equipment rated to high pressures both in absolute and in differential terms. Successful qualification of new high-yield metal alloys is a key enabler for delivery of high-pressure/high-temperature completion-equipment solutions; specifically in the development of a 20,000-psi-rated surface-controlled subsurface safety valve, 15,000-psi-differential-rated completion equipment, and 30,000-psi-rated downhole-test-tool equipment. The current mechanical-property limits for high-yield metal-alloy materials must be extended with material solutions that provide robust corrosion performance. Past experiences by many operators have led to a rigorous assurance process to ensure that new equipment will work and work the first time. Equipment statement of requirements, detailed design reviews along with comprehensive qualification plans, system-integration tests, and, potentially, field trials are part of the overall equipment-integrity assurance. As we continue to explore in deep water, new horizons at depths never before completed demand new ideas and new technologies to enable development. As professionals working in the oil industry, we need to continue working together to find new ways to develop these deeper high-pressure reservoirs and then to develop the equipment to produce them. We need to keep that "can-do" attitude.
