AI overview

Updated

Hephae Energy Technology develops ultra-high-temperature downhole drilling tools and electronics that make superhot rock geothermal wells drillable. Conventional oil and gas measurement-while-drilling equipment stops working reliably above about 200C, which is the temperature range geothermal wells need to reach to produce meaningful power, and Hephae builds robotics, sensors and electronics rated to 210C with a roadmap to 300C and beyond. Its products cover the life of the well, from drilling and completions through operations. The company is headquartered in Spring, Texas, with additional operations in Calgary, Spain and the United Kingdom.

What sets it apart

A team from harsh-environment oil and gas drilling applying that experience to a temperature ceiling nobody else has cleared: downhole electronics and robotics that survive superhot rock conditions where standard MWD and rotary steerable tools fail.

Downhole drilling hardware

A high-temperature integrated measurement-while-drilling system, rated for operation above 200C, that lets operators drill and steer geothermal wells in rock hot enough to destroy conventional downhole electronics.

  • Rated for ultra-high-temperature operation to 210C
  • Integrated measurement-while-drilling system rather than a single component
  • High-temperature electronics and sensors purpose-built for geothermal wells
  • Supports the well life cycle from drilling and completions through operations
