摘要： A tool and method for use with a drill string or the like in capturing an object in a cavity, such as subterranean borehole, include a mandrel, object engaging apparatus for latching the mandrel to the object as the tool is moved into the borehole, and string engaging apparatus for keeping the mandrel latched to the drill string as the mandrel is moved into the borehole and for unlatching the mandrel from the drill string when the drill string is rotated in a first direction with the mandrel latched to the object. A washover pipe and mill, which are connected to the drill string, may be moved into contact with the object after the mandrel is unlatched from the drill string for milling through the object. A ratchet allows the mill to move toward the object relative to the mandrel and prevents the mill from moving away from the object relative to the mandrel. The ratchet allows the mill to move away from the object when the drill string is rotated in the first direction and lifted relative to the mandrel. The string engaging assembly relatches the mandrel to the drill string when the drill string is moved away from the object and rotated in a second direction. The object engaging apparatus unlatches the mandrel from the object when the mandrel is moved away from the object and rotated in the second direction.

摘要： A hydraulic setting tool for packers capable of mechanically setting the packer and opening a valve in the packer in one trip. The tool comprises an outer sleeve and an inner mandrel coaxially disposed within the outer sleeve and adapted to move axially relative to the outer sleeve. The tool further comprises three locking mechnisms that unlock under different fluid pressure loads. Two of the locking mechanisms lock the inner mandrel to the outer sleeve in a run-in position. Once a sufficient fluid pressure has been reached to unlock both of these locking mechanisms, the inner mandrel moves upward relative to the outer sleeve to set the packer. A spring forces the inner mandrel into a third position relative to the outer sleeve, which is maintained by the third locking mechanism. This third position is used to open the packer valve.

摘要： A full opening subsurface control valve for use in subsurface closure of a well annulus. The valve includes a body with a sleeve reciprocably disposed in the valve body. The body is releasably attached to an upper tool string portion, and the sleeve is attached to a lower tool string portion. An actuator arm, mounted on the body and stationary with respect thereto, engages a ball valve element. When the body and sleeve are in a relatively converged position, the ball valve element is in a closed position. When the body and sleeve are in a relatively extended position, the ball valve is in an open position, such that the ball valve element, body and sleeve define a substantially unobstructed flow passage through the valve. A spring is utilized for relatively biasing the body and sleeve toward the converged position. The weight of the lower tool string portion overcomes the spring force such that the valve is maintained in an open position as it is longitudinally positioned in the well bore. A pressure balancing piston is provided for balancing forces exerted by test pressurization of the valve so that undesired opening of the valve is prevented.

摘要： A low pressure, high temperature composite bridge plug. The bridge plug comprises a mandrel with a plurality of slips disposed therearound. A wedge is initially attached to said mandrel and in planar contact with the slips for forcing the slips radially outwardly into gripping engagement with a wellbore. An elastomeric sealing element is disposed on the mandrel and compressed between the wedge and a shoulder on the mandrel to expand the packing element radially outward into sealing engagement with the wellbore. A plurality of ratchets retained in a ratchet body grippingly engage the mandrel to prevent the plug from unsetting. The mandrel, slips, wedge and ratchet body are preferably made of non-metallic, composite materials for easy drilling.
