Abstract
An acoustic surveying method includes computing at least one of a distance and direction between first and second subterranean boreholes. An acoustic pulsed is transmitted into a subterranean formation from the first borehole and received at three or more spaced receivers deployed in the second borehole. A distance between the two boreholes may be determined using longitudinally spaced receivers while a toolface to target direction (angle) may be determined using circumferentially spaced receivers.
