摘要： An object carrier including a housing having a bore with a diametrically larger portion and a diametrically smaller portion, an object keeper having a first and a second end, the first end being initially disposed in the diametrically smaller portion, an actuator assembly configured to move the first end of the object keeper from the diametrically smaller portion to the diametrically larger portion responsive to selected application of pressure, and an object disposed within the object keeper and secured within the object keeper while the first end of the object keeper is in the diametrically smaller portion, the object being released from the object keeper upon the first end of the object keeper moving to the diametrically larger portion. A method for managing an object-based operation downhole of a restriction including pressuring up on the object carrier, withdrawing the first end from the diametrically smaller portion, and releasing the object.

摘要： An apparatus for removing a casing from a borehole penetrating a formation in one run of the apparatus in the borehole includes: a carrier conveyed in the borehole; a non-incendiary hole former on the carrier to form a hole in the casing; a fluid discharge device on the carrier to discharge a fluid into the hole to wash an exterior portion of the casing; a casing puller on the carrier and having a casing grip to grip the casing to lift the casing or a portion of the casing out of the borehole; a mechanical cutter on the carrier to cut the casing; and a valve on the carrier to control fluid energy to least one of the non-incendiary hole former, the fluid discharge device, the casing puller, and the mechanical cutter.
