Abstract: A technique facilitates pressure containment with a retrievable cement bushing. The retrievable cement bushing comprises a body having an internal longitudinal passage. Additionally, the retrievable cement bushing comprises an engagement lug which cooperates with a sleeve. The engagement lug is mounted on the body and is movable to a radially outward position for engagement with a corresponding portion of a surrounding wall, e.g an internal packer wall. The sleeve is sized to receive a slick joint therethrough and is movable to a radially inward position relative to the engagement lug so as to hold the engagement lug in the radially outward position. The sleeve protects the slick joint from inwardly directed loading via the engagement lug when the retrievable cement bushing is subjected to differential pressures.

Abstract: A retrievable packer has its sealing system unloaded before the slip system is relaxed by separation of slip cones from slips that flank the seal assembly. The mandrel is cut so that the portion above the cut can be raised to take a cone up and away from collet heads which previously were trapped by the cone. The collet heads are disposed between opposed sloping surfaces so that the retraction of the cone from under the heads allows the residual rubber pressure to force the heads toward the mandrel into the space created by relative movement of the mandrel that took the wedge cone uphole. The heads are at ends of fingers having a radially inward bias to further assist retraction of the heads toward the mandrel. With the heads retracted the sealing element stretches out before slip cones are moved relative to the slips.

Abstract: A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation.
