Tech Trends: ESP System for High Temperature Applications

The Schlumberger REDA HotlineSA3 high-temperature electric submersible pump (ESP) system can reliably produce from wells with bottomhole temperatures of up to 250 degC, thus enabling the installation of the ESP in early stages of development

 

The Schlumberger REDA HotlineSA3 high-temperature electric submersible pump (ESP) system can reliably produce from wells with bottomhole temperatures of up to 250 degC, thus enabling the installation of the ESP in early stages of development. The HotlineSA3 system, which builds on years of development and lessons learned from the REDA Hotline550 ESP system, incorporates a newly integrated design that effectively extends the ESP operating envelope and run life. Reduction of subcool and Steam Oil Ratio (SOR) is achieved with integrated surveillance and control through reliable fluid pressure, temperature and internal motor measurements.

This new ESP system enables operators working in high-temperature applications—steam-assisted gravity drainage (SAGD), steamfloods, in situ combustion, and geothermal—to improve economics through increased recovery and the ability to begin producing earlier while also reducing downtime and intervention costs. The new system has passed extensive testing while running at maximum-rated temperatures, including strict third-party qualifications and extensive field testing in SAGD fields throughout Canada and steamflood fields in Oman. The system has surpassed the criteria set for field testing, logging in excess of 2,000 combined cumulative running days for eight different operators. Individual units have surpassed 250 days at the highest-rated temperatures to date.
