The present application discloses an apparatus and method for determining the diameter of a borehole. The method includes disposing an acoustic tool at a first depth in a borehole. The acoustic tool may include a source and a receiver. The source of the acoustic tool may generate a plurality of waves at a first depth of the borehole. The waves may include at least one of a compressional wave and a refracted shear wave. The receiver of the acoustic tool may receive a wave and at least one of a velocity and an arrival time of the wave may be determined. Additionally, a velocity of drilling mud surrounding the acoustic tool may also be determined. Using on one or more of the velocity, the arrival time, the mud velocity, an acoustic tool dimension, and a distance between the source and the receiver, a diameter of the borehole may be determined. |
