REDA Thermal

Power-efficient geothermal electric submersible pump

Reliable, high-flow-rate pumps for high-enthalpy geothermal systems

REDA Thermal power-efficient geothermal electric submersible pumps reliably lift fluids in high-enthalpy geothermal wells, delivering high flow rates with maximum electrical efficiency, minimal maintenance, and long run life.

The combination of reliability and efficiency enables profitable production from geothermal wells that were previously uneconomical to produce—with minimal parasitic power load. This makes REDA Thermal pumps an ideal replacement for line-shaft pumps that are limited by depth and well profile, require maintenance, and are time consuming to install. Traditional ESP technology alleviates some of these challenges, but their run life is unacceptably short at common geothermal well temperatures >400 degF [>200 degC].

Max. bottomhole temperature: 440 degF [225 degC]

Casing size: 9 5/8 in and larger

Flow rates: up to 960 m3/h [4,225 galUS/min]

Faster installation, high efficiency, and long run life at ultrahigh temperatures

Using energy-efficient permanent magnet motor (PMM) technology and motor sections with high power density, REDA Thermal pump performs reliably in geothermal wells at setting depths up to 5,000 ft [1,500 m]. The modular assembly accelerates installation, reducing rig time from several days (for a typical line shaft pump installation) to a few hours.

Optional downhole monitoring sensors enable monitoring of pump and reservoir operating parameters and control of some pump functions to extend run life.

REDA Thermal pumps are the product of more than 100 years of ESP development and deployment, including decades in steam-assisted gravity drainage (SAGD) projects, where lower-flow-rate ESP systems operate with run life exceeding 6 years in harsh oil environments up to 480 degF [250 degC]. The most recent advances include novel materials and elastomers to survive geothermal fluid composition and temperatures.
