uHPHT Single-Shot Reservoir Testing Systems

The uHPHT-rated K-String configuration is designed to accommodate downhole temperatures to 500 degF, differential pressures to 17,500 psi, and annular pressures to 30,000 psi. It is currently based on single-shot tools and has a rugged yet simple design. The single-shot K-String can be run with a dual-action valve (DAV) in the string, providing a second buildup option for more flexibility in test design while ensuring the same reliable single-shot principle. When run with the DAV-K tool, the K-String is rated to 450 degF.
