TRSG-UU (Logging tool)

Model id: Robertson Geologging 45 mm Full-waveform Triple Sonic with natural gamma; TRSG9039


  • full waveform data (sonic probe)
  • seismic velocity, p wave
  • total natural gamma

Purpose: sonic velocity of the rock, full waveforms from each of the three receivers, after processing Vp and maybe Vs

Description: Geotechnical/mining/water, Fracture and permeability indication in hard rock, Rock strength and elasticity, Lithology identification, Porosity, Correction of seismic velocity

Characteristics: Formation velocity (slowness), Time of first arrival (delta-t), Integrated transit time, Full-waveform data from 3 receivers, Shear and Stoneley velocities (requires additional interpretation software), Natural gamma
