Abstract

A completion method involves a telescoping joint in the completion string that needs to be locked when pumping fluid through it as part of the completion method. The joint is locked with two locks and one is thermally activated using a shape memory locking member to handle the stresses from component contraction. The setting of the thermally actuated lock occurs when the temperature is lowered during pumping. At other times the temperature of well fluid defeats the thermal lock leaving a non-thermal lock actuated until such time that the telescoping joint can be used in production. The non-thermal lock is defeated so allow normal telescoping action during production. The non-thermal lock is defeated with string manipulation or pressure or other ways depending on its design.
