Reduction of expansion force via resonant vibration of a swage

An apparatus for deforming a wellbore tubular in a wellbore, comprising:

• a body deforming the wellbore tubular;
• a setting tool configured to apply a static force to the body to deform the wellbore tubular;
• and
• an ultrasonic vibration device connected to the body by a connector, wherein the vibration device includes a transducer stack, and a function generator applying a driving signal to the transducer stack, the vibration device applying a vibration to the body via the connector at a fraction of a resonant frequency of the body to cause the body to resonate at a resonant frequency, wherein the body resonates by diametrically expanding and contracting in response to the vibration, wherein a mass of the body and a frequency of the vibration are selected to generate a dynamic force for deforming the wellbore tubular, and wherein the setting tool and the vibration device cooperate to cause a substantially constant relative motion between the body and the wellbore tubular.

A system for deforming a wellbore tubular in a wellbore, comprising:

• a rig at a surface location;
• a work string disposed in the wellbore;
• a setting tool configured to generate a static force to deform the wellbore tubular;
• a body connected to the work string, the body being shaped to deform the wellbore tubular upon engaging the wellbore tubular;
• and an ultrasonic vibration device connected to the body by a connector, the vibration device applying a vibration to the body via the connector at a fraction of a resonant frequency of the body to cause the body to resonate at a resonant frequency, wherein the vibration is configured to apply impulsive blows having a non-sustained amplitude, wherein the body resonates and diametrically expands and contracts in response to the vibration, wherein a mass of the body and a frequency of the vibration are selected to generate a dynamic force for deforming the wellbore tubular, and wherein the setting tool and the vibration device cooperate to cause a substantially constant relative motion between the body and the wellbore tubular.
