The HP/HT Completion Landscape

The methods used for high-pressure/high-temperature (HP/HT) tool development are evolving, and development cycles are lengthening, particularly for ultra-HP/HT applications (those involving pressures greater than 15,000 psi or temperatures greater than 350°F) in which materials screening and stability assessments are required. What can the industry anticipate for future HP/HT wells in terms of architecture, product development, and regulatory challenges? This paper identifies current development paradigms and discusses the future challenges in well planning, product development, and regulation.

HP/HT Completion Technology Challenges

The technological challenges associated with the completion of wells at and above HP/HT conditions are diverse and continue to increase. Previous investigations into HP/HT projects identified technology gaps related to packers, bridge plugs, liner hangers, subsurface safety valves (SSSVs), tubing-to-packer seals, and related products. (Please see the complete paper for a comprehensive list of challenges faced in HP/HT environments, as well as a discussion of the historical perspective in HP/HT well development.)

In addition to the general challenge of materials design and testing for HP/HT environments, several specific component-based challenges also exist.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 170919, “The HP/HT Completion Landscape—Yesterday, Today, and Tomorrow,” by Douglas J. Lehr and Scott D. Collins, Baker Hughes, prepared for the 2014 SPE Annual Technical Conference and Exhibition, Amsterdam, 27–29 October. The paper has not been peer reviewed.
