Abstract: A seal assembly including 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 has 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 included that is triggerable for reconfiguring the radial dimension of the seal element. The sealing surface of the first tubular operative forms 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. A method of sealing tubulars is also disclosed.

Abstract: A completion assembly of a top packer and zone isolation packers separated by screens has a disconnect in a selected zone to be fractured or gravel packed that is armed before such a procedure starts. Initially when the assembly of the outer completion and the inner string are properly located and all the screens valved off, all the packers are pressure set and the packer set release device associated with each packer is armed. Before starting a fracturing or gravel packing operation from a given zone isolation packer, a disconnect for that zone packer is armed so that if the inner string sticks in that packer, the inner string is sheared and removed and another trip is used to grab the top packer and pick up. Such picking up releases all the packers down to the one armed disconnect. The disconnect releases bringing up the remnant of the inner string stuck in the packer just above the actuated disconnect.

Abstract: A selective sleeve system includes, a tubular, a sleeve movably disposed at the tubular, and a movable member having at least one dog radially biased and configured to be radially displaceable into a recess. The at least one dog is positionable perimetrically adjacent to at least one tab, subsequent displacement into the recess to radially overlap with the sleeve sufficiently to move the sleeve relative to the tubular upon movement of the movable member relative to the tubular.
