ABSTRACT:
A method and apparatus for determining the position of the bottom end of a long pipe in a deep water-filled borehole, comprising generating a shock wave in the water at the surface end of the pipe, timing the travel of the shock wave down the pipe to the bottom end thereof, where the shock wave will pass into the liquid in the borehole, generating an expanding seismic wave in the earth. Setting out a plurality of geophones on the earth at the surface to detect the arrival of the seismic wave. Recording the geophone signals and determining the arrival times of the seismic wave. Determining the travel times of the seismic wave to each geophone and determining the position of the end of the pipe.
