ABSTRACT:
A well casing perforator for efficiently recovering available water in a previously drilled well by perforating the well casing. The well casing perforator generally includes a frame adapted to be inserted within a well casing and move in a direction parallel to a central longitudinal axis of the well casing, at least one perforator pivotally connected to the frame and including a plurality of spikes extending therefrom for engagement with the well casing and at least one spring to impart a bias force upon the perforator so that the spikes automatically grab the well casing and rotate through the well casing with a change in directional movement of the frame.
