DOWN HOLE
DDH-Geo
Triaxial down-hole Geophone
The new triaxial borehole geophone, designed to seismic applications as Down- Hole survey.
Provided with a fast-locking system with oriented aluminum poles, it allows to perform double setting configuration aimed to differential travel time processing.
. It also guarantees a high accuracy and fulfilling of international standard, ASTM D7400.

DOWN HOLE
Hammer Switch
Down-hole trigger
Thanks to the experience of Solgeo in piezoelectric sensors, a robust and reliable trigger has been developed, ideal for the execution of downhole and seismic surveys in general.
This device consists of a durable case and a sensor coated with epoxide resin that ensure a much longer lifetime than other devices on the market.
Applications
  • Down-hole
  • Seismic refraction
  • Seismic reflection
