摘要

Methods and apparatus to combine monopole and multipole acoustic logging measurements to determine shear slowness are disclosed. An example method to determine shear slowness of a formation from acoustic logging data disclosed herein comprises determining a plurality of mixed coherence values corresponding to a respective plurality of possible shear slowness values, each mixed coherence value determined by combining a monopole coherence value determined from monopole logging data and a multipole coherence value determined from multipole logging data, the monopole and multipole coherence values each being determined for a particular possible shear slowness value corresponding to the mixed coherence value, and using the particular shear slowness value corresponding to a maximum mixed coherence value in the plurality of mixed coherence values to represent the shear slowness of the formation.
