WebDec 20, 2024 · Borehole geophysics is the science of recording and analyzing measurements of physical properties made in wells or test holes. Probes that measure … 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.
