ACOUSTIC SENSOR APPARATUS, SYSTEMS, AND METHODS

摘要

In some embodiments, an apparatus and a system, as well as a method and an article, may operate to acquire multiple output values provided by at least one elongated, unitary acoustic sensor operating as a secondary propagation medium. The sensor has multiple mechanical-to-electrical conversion probe points along its length, to provide corresponding multiple output values proportional to mechanical movement along the length of the sensor, the mechanical movement being induced by acoustic waves in a primary propagation medium comprising a geological formation and borehole fluid. Further activity may include processing the output values to determine slowness in an acoustic wave propagating between at least two of the probe points. Additional apparatus, systems, and methods are disclosed.
