Abstract
A work string and method of absorbing a vibration at the work string. The work string includes an outer member, an inertial mass disposed within the outer member and a damping element between the outer member and the inertial mass. The damping element includes a liquid having a viscosity that increases with increasing temperature. The damping element absorbs the vibration being transferred from the outer member to the inertial mass.
