ABSTRACT:
A technique is provided for controlling actuation of a well component. A resistance device is deployed in a tool string and connected to a well tool to be actuated. The resistance device comprises a deformable body and a deforming member that move relative to one another during actuation of the well tool. Deformation of the deforming member provides constant resistance and consequent control over component actuation.
