Abstract
This invention relates to a tool for recovering a downhole equipment stuck in the formation. The tool provides for the use of a power source mounted a distance above the equipment to be recovered. An elongated shaft is rotationally connected to the power source, the shaft having unbalanced weight which is distributed over at least a part of its length. When the power source transmits torque to the shaft, the shaft begins to vibrate, transmitting the vibration to the downhole equipment which causes loosening of the soil surrounding the equipment and facilitates recovery of the equipment.
