Work package 4

Deep geothermal tool upgrade

Objectives:

• Design, construction and testing of an environmental protection system to allow the borehole radar electronics

developed in WP3 to be deployed in deep geothermal wells.

• Development and testing of a high temperature borehole radar antenna suitable for running in deep geothermal

wells below the electronics.

• Design and production of a non-conductive, pressure and temperature rated tether to connect the borehole

radar antenna and the electronics assembly.

• Design and construct a complete core radar module based on the HDR technology of GGEO and increase the

dynamic range with up to 25 dB compared to earlier generations of borehole radars.

• Develop firmware and software for the radar system and interface with ALT well software stack.

• Develop enclosure needed to integrate the core radar module with the environmental protection system.
