downhole muon instrument

Muon Instrument for subsurface density imaging

Following recent testing in at a Norwegian test site, Geoptic are pre-releasing information on its downhole muon instrument for wider geophysical subsurface investigators.

The instrument’s key features include:

  • Weight : 15kg

  • Diameter : 60mm, suitable for HQ standard boreholes

  • Length : 2.2m

  • Extensible - Multiple muon detectors can be deployed in a string to increase data rate and reduce on-site time. 

  • High-Pressure Resistance - The detector housing has been successfully tested to an equivalent depth of 1.5km of water. The housing’s crush depth is 3km of water.

  • Temperature Range - The instrument can be operated in temperatures to 60 degrees Celsius. All components are specified to 85 degrees Celsius.

  • Complementary Sensing - A string of muon detectors is designed to work with hydrophones to provide a flexible subsurface imaging system.

  • Standard four-core electrical cable - Power and standard communications in a single cable

  • Simplified deployment options - An end cap with a standard four pin Gearhart-Owen connector is available for single detector deployment. For a multi-detector string deployment, a weight-bearing steel cable and separate electrical cable can be supplied, allowing common winches to be used (such as those used on drill rigs, see left-hand image)

The system provides 3D density information for near-surface engineering and geophysical projects.

The instrument is available for service testing prior to commercial release.
