摘要： A wash tool comprises a mandrel with a central annulus and one or more lateral bores and one or more ring-shaped rotary hubs positioned about the mandrel adjacent to the one or more lateral bores. The rotary hubs comprise lateral bores perpendicular to the lateral bores of the mandrel such that pressurized fluid introduced to the central annulus of the mandrel impacts the inner surface of the rotary hubs and forces them to rotate, delivering pressurized fluid to the inner surface of a wellbore or tubular. The wash tool is modular and can be attached to a top sub or bottom sub, and may be used with or without a wireline. When used with a wireline, the wireline is insulated from the wash fluid by means of a tie-back and multiple seals.

摘要： A conversion kit creates a redundant hydraulic, pneumatic, or mechanical control Functionality for low-torque, quarter-turn plug valves in remote production environments (i.e., rural or subsea pipelines). The conversion kit comprises at least one custom end cap fitted to the valve and comprising a socket receiving a rotator attachment. Each rotator attachment is in turn connected to a crossover which connects to a bracket remotely actuated via hydraulic, pneumatic, or mechanical control The linear movement of the bracket and the attached crossover[s] is converted to rotational force which is transmitted through the rotator attachments to the at least one valve.

摘要： A torqueing tool for rotating bolts connecting a pipe flange in a subsea environment, comprising a first guide for guiding movement of the torqueing along a pipe, a socket for engaging a first bolt, a shaft for transferring torque from a motor to the socket, and a first protruding member for insertion between the pipe and a second bolt of the pipe flange, to prevent the torqueing tool from rotating due to counter torque created while applying torque to the first fastener. The torqueing tool can further comprise a second protruding member adjacent the socket, wherein the second protruding member can be inserted between the pipe and a third bolt of the pipe flange. The torqueing tool can further comprise an angled shaft for transferring torque from the motor to the socket, wherein an axis of rotation of the motor is different from an axis of rotation of the socket.

The connector assembly comprises a female union connector having an axial bore extending therethrough, internal threads, and an internal shoulder. The connector assembly also comprises two male connectors, each male connector having an axial bore extending therethrough and external threads. The connector assembly further comprises two ring- shaped seals adapted to form a fluid seal between the female union and the male connectors. The first seal contacts the first side of the internal shoulder and a front end of the first male connector to form a fluid seal therebetween. The second seal contacts the second side of the internal shoulder and a front end of the second male connector to form a second fluid seal therebetween.

摘要： Systems and methods enable connection of, and are usable to connect, well servicing equipment to other well equipment, including wellheads, blowout preventers, and other well servicing equipment. The systems comprise connecting apparatus having a male connector and female connector. The male connector comprises an elongate body having an axial bore extending therethrough and a plurality of protrusions extending from the elongate body at an angle relative to the axial bore. The female connector can be adapted for connection with the male connector, wherein engagement between the male connector and female connector communicates the axial bore of the male connector with a bore of the female connector to define a flowpath for communicating a medium. The systems and methods enable the ability to connect or disconnect well equipment remotely without the need of a diver, an ROV, and without the need to bring the well equipment to the surface for disassembly.
