Abstract
A method and apparatus for maintaining a second elongated hole axis substantially parallel to a previously bored horizontal hole axis which entails inserting a seismic signal generating apparatus into one hole and a seismic signal receiving apparatus into the other hole. The seismic receiver includes apparatus for moving it along the axis, for maintaining the receiver substantially parallel to the gravitational bottom of the hole, and for moving the receiver a predetermined distance from the borehole wall which is adjacent the borehole containing the seismic signal generating apparatus. Apparatus for observing the detected signal is located outside the borehole.
