ACOUSTIC STEERING FOR BOREHOLE PLACEMENT

摘要

Apparatus (100), systems (110), and methods may operate to generate acoustic emissions from within at least a first borehole (120), receive the acoustic emissions within a second borehole (136), and process the acoustic emissions to locate a borehole bit (132) in formational space as the borehole bit is steered along a path within one of the first borehole or the second borehole. The acoustic emissions may be received by a plurality of acoustic receivers arranged in several ways, including linear and planar arrays. Additional apparatus, systems, and methods are disclosed.
