Abstract

An acoustic ranging system utilizes gradiometric data to determine the distance between a first and second well without any knowledge or involvement of the borehole or formation characteristics. An acoustic signal is generated from a downhole or surface source, propagated along a first well, and then received by receivers (22) positioned along the second well. Processing circuitry coupled to the receivers (22) takes a ratio of the absolute signal to the gradient signal in a certain direction to thereby determine the relative position and distance between the two wells.
