Abstract
A method for determining position of a wellbore in the Earth's subsurface can include: actuating a seismic energy source at a selected location along the wellbore; detecting seismic energy with sensors located at known geodetic positions along the wellbore, the detected seismic energy being at least partially reflected by a casing of an adjacent wellbore; and determining the geodetic position of the wellbore at the selected location from the detected seismic energy.
