WebDec 14, 2024 · Borehole Sonic Logging is based on the principle of measuring the travel time of Compressional (P), Shear (S) and Stoneley waves propagating along a borehole with different radial depths into the formation. The operating frequency range for these measurements is typically from 0.5 to 20 kHz. This helps to probe several meters into the … WebThe velocity of the refracted wave along the borehole wall remains V f. Each point reached by the wave acts as a new source retransmitting waves back into the borehole at velocity V m.
