Abstract: A kickover tool having a ratcheting mechanism comprising a ratchet arm and a ratchet track. The ratchet arm is pivotally attached to an arm assembly and the ratchet track is attached to a surface of the main body. A method for operating the kickover tool apparatus can include the tool being able to traverse a tubing string and place or retrieve a tool or object from a side pocket mandrel. A string of two or more kickover tool apparatuses can be used to retrieve and/or place two or more separate tools or objects in one or more side pocket mandrels during a single trip operation. The kickover tool can function without placing any side loads on the side pocket device during the placing or retrieving procedure, thereby preventing any bending or fracturing of the side pocket device.

A method for operating the kickover tool apparatus can include the tool being able to traverse a tubing string and place or retrieve a tool or object from a side pocket mandrel. A string of two, or more, kickover tool apparatuses can be used to retrieve and/or place two, or more, separate tools or objects in one, or more, side pocket mandrel during a single trip operation. The kickover tool can function without placing any side loads on the side pocket device during the placing or retrieving procedure, thereby preventing any bending or fracturing of the side pocket device.

Abstract: A surface controlled subsurface safety valve assembly includes primary and secondary valves, such as an upper and lower flapper valve. Only one of the valves is in service at a time. In the event that the primary valve is compromised, and therefore leaks, the SCSSV is shifted to position the primary valve out of service and the secondary valve in service. The SCSSV may have more than two flappers, thereby providing multiple secondary valves, with only one valve in operation at any one time.

Abstract: In a multiple well completion, spaced apart production packers isolate independent production zones from one another. In each isolated production zone, a side pocket mandrel with a full opening bore has lengthwise extending side by side elongated pockets (1) for receiving a static pressure measuring instrument or tool (static pressure pocket); (2) for providing a venturi flow passageway (flow passageway pocket); and (3) for receiving a differential pressure measuring tool (differential pressure pocket). The static pressure measuring tool and the differential pressure measuring tool or instrument are commonly connected by a data coupling means to a single electrical conductor line which is strapped to the string of tubing and extends to the earth's surface for transmission of control signals and data signals between the earth's surface and the various side pocket tools.

Abstract: A side pocket mandrel for providing a top entry electrical connection from a bottom location in the mandrel comprised of cylindrically shaped parts (119a-119g) connected end to end to form an elongated housing having an offset full opening bore where said housing has 1) a laterally offset upper recess (167) in communication with the full opening bore for receiving a well tool (117) moved laterally from the full opening bore, 2) a lower laterally offset pocket bore (125a, 125b) for receiving the well tool, 3) a laterally offset lower recess (127), 4) at least one laterally offset, longitudinally extending and separately located pipe bore (140) extending alongside of the offset pocket bore for connecting the upper recess to the lower recess, and 5) at least one outlet bore (168) extending between the upper recess and the housing's exterior.

Abstract: The present invention is a combination wireline retrievable, side pocket locatable, fluid measurement and control assembly, which permits measurement and control of fluid from a first downhole production zone while maintaining fluid flow through the tubing from other downhole production zones. The various components of the fluid measurement and control assembly may be separately installed in or retrieved from by either wireline or coiled tubing intervention methods and can remain installed in the production tubing while installing or retrieving other downhole tools through wireline or coiled tubing intervention methods.

Abstract: An apparatus for welding a section of pipeline onto an existing pipeline, the process including the steps of cutting away the section of damaged pipeline; providing a apparatus insertable within each end of the existing line for venting off gas within the line to create a gas free safety zone around the cut ends of the line; providing a flange for welding onto the ends of the line, the flange including a ring for sealingly engaging the face of a mating flange to effect an initial seal between the flanges while a weld bead is welded in place between the mating flanges. Following the welding, there is provided a test port in the wall of the flange for allowing air or fluid to be injected into the annular space between the metal sealed ring and the weld so as to test for any leak in the weld in place. Further, the sealing ring and test ports are in a position so that the exterior weld between the flanges may be X-rayed for any flaws within the weld.
