Abstract
In some embodiments, apparatus and systems, as well as methods, may operate to record a plurality of acoustic waveforms comprising cross-dipole waveforms and corresponding to acoustic waves received 5 at azimuthally orthogonal dipole receiver arrays surrounded by a geological formation, the waves being generated by azimuthally orthogonal dipole transmitter arrays. Further activity may include defining an objective function dependent on the cross-dipole waveforms, eigenvalues, an azimuth angle corresponding to an 10 orientation of the transmitter and receiver arrays; minimizing the objective function with respect to said angle and the set of auxiliary parameters; and determining at least one property of the geological formation based on the global minimum. Additional apparatus, systems, and methods are disclosed.
