The Suspension P-S Logging System is a new technique for measuring P and S-wave velocities in deep boreholes. The characteristic feature of this technique is that the downhole sonde contains both the electromagnetic vibration wave source and two receiver units separated by flexible tubing. The sonde suspended in a fluid …
