(57) Abstract:
An acoustic position measurement system (23)
and method includes an acoustic transmitter
operable to transmit a sound wave into an
underground well bore (18) in a target
formation (26). The sound wave is configured
to reflect from a boundary formation (28,29)
proximate the target formation. The system
includes an acoustic receiver operable to
receive a reflected sound wave. The reflected
sound wave comprises a reflection of the
sound wave from the boundary formation. The
system also includes an electronics portion
electrically coupled to the acoustic receiver.
The electronics portion is operable to process
the reflected sound wave and produce, based
upon a characteristic of the reflected sound
wave, data output indicative of a position of
the acoustic position measurement system in
the target formation.
