Abstract:
An apparatus includes a body shaped to deform a wellbore tool in a predetermined manner. A vibration device applies a vibration to the body to reduce a frictional force caused when the body deforms the wellbore tool. In one arrangement, the vibration devices imparts a resonant wave motion to a swaging apparatus that is being pushed through a passage of a wellbore tubular. A swaging body vibrates at a resonant frequency along the long axis of the wellbore tubular and/or normal to long axis of the wellbore tubular. The relative motion between the swaging body and the tubular member reduces the force required to expand the wellbore tubular. Optionally, a controller operatively connected to the vibration device adjusts the operation of the vibration device in response to the sensor measurements of the vibrations in the swage body.
