Patent Images
1. An apparatus, comprising:
- a first plurality of acoustic receivers to be located within a first borehole in a geological formation and to receive acoustic emissions from a plurality of acoustic sources in a second borehole as it is formed in a geological formation using a borehole bit; and
an acoustic processing module to locate the borehole bit in formational space as the borehole bit is steered along a path in the geological formation.

Abstract
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.
