A gooseneck conduit assembly includes a gooseneck conduit including a vertically-extending portion, an upset formed on the vertically-extending portion, an alignment key extending laterally from the vertically-extending portion, and a lower coupling at a lower end of the vertically-extending portion; a second conduit configured to connect to an auxiliary fluid line connected to and extending along a riser string that extends to a subsea wellhead, the second conduit including a receiving end configured to form a connection with the lower coupling; and a frame configured to be connected to the riser string. The frame includes an upper bracket vertically offset from a lower bracket to which the second conduit is secured, an alignment groove configured to slidably receive the alignment key so as to maintain a coaxial alignment between the vertically-extending portion of the gooseneck conduit and the second conduit, and a locking member pivotally coupled to the upper bracket.

A tool trap system that includes a housing. The housing defines a bore. A shaft couples to the housing. A flapper couples to the shaft. The flapper rotates with the shaft between an open position and a closed position to control movement of a wireline tool through the bore. An actuation system couples to the shaft. The actuation system rotates the shaft. The actuation system includes a lever that couples to and rotates the shaft. A cylinder contacts the lever. The cylinder moves axially along a longitudinal axis of the cylinder to rotate the lever.

The present invention is a rod jack apparatus with four vertical legs that form a framework and first and second lower brackets connected to the vertical legs. Two hydraulic cylinders extend upwardly from the lower brackets, pass through a first horizontal plate, and are connected to a second horizontal plate. A primary clamping mechanism is situated on top of each of the two horizontal plates, and a secondary clamping mechanism is attached to the underside of each horizontal plate. The apparatus is configured to receive a polished rod, and the primary and secondary clamping mechanisms are configured to grip the polished rod when activated. The sucker rod assembly is lifted out of the well when the first and second hydraulic cylinders are extended. The invention includes a method of using the apparatus described herein.

A clamp assembly, for mounting around a tool joint coaxially joining cylindrical upper and lower workpieces, comprises an upper collar assembly and a lower collar assembly, each having semi-cylindrical left and right collar segments. The left and right collar segments of each collar assembly are removably connectable to each other by threaded fasteners to form the collar assembly. The upper and lower collar assemblies are coaxially mountable around the upper and lower workpieces, respectively, such that tightening the fasteners will urge the upper and lower collar assemblies to grip the upper and lower workpieces, respectively, and thus to provide increased resistance to relative rotation between the two workpieces about the tool joint axis. The upper and lower left collar segments, and/or the upper and lower right collar segments, may be interlockingly and radially slidable relative to each other to accommodate differences between the outside diameters of the two workpieces.

A connector system and method, of which the connector system includes a first conduit having a lower coupling and a first alignment feature, and a frame configured to be coupled to an oilfield tubular, and configured to receive the first conduit and a second conduit. The frame includes a second alignment feature configured to mate with the first alignment feature such that the lower coupling is aligned with the second conduit, and the first alignment feature is configured to slide vertically with respect to the second alignment feature such that the lower coupling is brought into engagement with the second conduit while the first and second alignment features are mated together.

A clamp for attachment to a blow out preventer (BOP) stack for lifting and/or maneuvering the BOP stack and a method for attaching the clamp to the BOP stack is described. The clamp is formed from a first and second clamp half which are connected together using male and female connectors located at inner mating surfaces of the clamp halves, and locking connectors located at the outer edge of the clamp halves. The clamp includes at least two connection points for attaching the clamp and/or clamp halves to lifting devices for moving each clamp half and/or the whole clamp and BOP stack.

Sealing/locking rod safety clamp systems and components are provided. In some embodiments, the systems can comprise a locking rod clamp, a lockable drive motor shaft, and locking shaft rams. Methods of use of sealing/locking rod safety clamp systems and components are also provided.
