WebJan 27, 2015 · Installation of PS Logging Equipment (Downhole seismic method) in field (Date of testing, 02/08/13) From the calculated travel time of the compression and shear … WebSonic or Acoustic borehole logging measures the travel times of elastic waves through the formation. From the travel times the wave velocities (P and S) are readily calculated, determining Poisson’s ratio. With the addition of density values small strain moduli can be directly determined i.e. Shear Modulus, Young’s Modulus and Bulk Modulus.
