Abstract:
A seal assembly includes a first tubular having a sealing surface, and a seal element run with the first tubular and displaced from the surface. The seal element initially having a radial dimension that forms a radially innermost or outermost sealing dimension of the first tubular for enabling the first tubular to be sealed with a second tubular radially disposed with the first tubular. A mechanism is triggerable by axial movement for reconfiguring the radial dimension of the seal element. The sealing surface of the first tubular operatively forming the radially innermost or outermost sealing dimension of the first tubular when the radial dimension of the seal element has been reconfigured for enabling the sealing surface of the first tubular to receive a second seal element. The seal element is axially compressed and released to change the radial dimension of the seal element.
