Shear wave logging in slow formations

Shear wave travel times can be used in conjunction with P wave travel times to help the log analyst evaluate formations more effectively. In hard or faster formations, where the shear speed in greater than the speed of sound in the drilling mud, shear waves appear as distinct arrivals on full waveform sonic logs. In soft or slower formations, where the shear speed is less than the mud speed, shear waves cannot be bent back into the borehole and are therefore absent from the wavetrain. it is possible to use the Stoneley wave speed together with the P wave travel time, caliper and density logs to compute the formation shear speed offline. The authors present two examples of this technique.
