Abstract
A method for determining an acoustic anisotropy of a subterranean formation includes measuring acoustic wave slownesses at three or more toolface angles while rotating a logging while drilling tool in a borehole. Compressional, shear, and/or guided wave slownesses may be measured. The measured slownesses are fit to a mathematical model to obtain maximum and minimum slownesses. The maximum and minimum slownesses are processed to determine the acoustic anisotropy of the formation.
