ABSTRACT:
The auger is attached to a spiral gear and a spring, the apparatus then being connected to the downhole, leading end of the logging sonde. When the auger nose of the modified sonde assembly strikes any of various obstructions on the sidewall that cause it to lose momentum, such as a rock ledge, the momentum of the heavy sonde causes the auger nose assembly to compress, forcing the auger to rotate on the spiral gear. The rotational action thus produced allows the auger to pull the sonde to pass the obstruction. After the obstruction has been passed, the potential energy stored in the spring induces the auger to return to its original extended position, whereupon it is ready to encounter and pass another obstacle.
