Abstract

Disclosed herein is a decelerating device. The device includes, a body movably engagable within a tubular, a mandrel longitudinally movably disposed at the body, and at least one deceleration element disposed at the body in operable communication with the mandrel such that longitudinal movement of the mandrel with respect to the body causes controlled radial movement of the at least one deceleration element to decelerate the decelerating device in relation to the downhole tubular.
