HP/HT Challenges

Ultradeep HP/HT Completions: Classification, Design Methodologies, and Technical Challenges

Traditional understanding of high-pressure/high-temperature (HP/HT) applications, 10,000 psi and 300°F, is common. The HP/HT working envelope has been extended to 15,000 psi and 400°F, with some limited gaps related to completion-size availability rather than technology needs. This larger envelope is being pushed further to 20,000 to 30,000 psi and 400 to 500°F. The technology gaps associated with this new HP/HT frontier are not limited to completion equipment but include casing, tubing, blowout preventors, wellheads, perforating, lubricators, logging, and drilling.
