ABSTRACT:
The shear wave velocity of the formation is determined by logging the fastest component of the guided wave generated by the generating means. This method is advantageous for logging the shear wave velocities of soft formations. If the generating means of a multipole acoustic logging device radiates at frequencies including a critical frequency, the fastest component of the guided wave generated by the generating means will have substantially the same velocity as a shear wave traveling in the earth formation. By logging the velocity of this fastest component, the shear wave velocity of the earth formation is determined.
