1. A method for facilitating operations in a wellbore comprising:

dropping a tripping ball to a restricted dimension portion of a tubular member;

pressuring up to a selected pressure on the ball to actuate a pressure actuated well process; and

applying a tensile load to the tubular member to reconfigure the restricted dimension portion of the tubular member to a position capable of passing the ball therethrough.

2. The method for facilitating operations in a wellbore of claim 1 wherein the applying a tensile load to the tubular member includes at least one of applying hydraulic pressure and applying mechanical forces.
