A tool configured to align a polished rod within a carrier bar of a pumpjack is described. While this tool can include any suitable component, in some cases, it includes a cylindrical member having an internal conduit, allowing the cylindrical member to wrap around and receive the polished rod. In some cases, the cylindrical member has a top having a first outer diameter, and a bottom having a second, larger outer diameter. In some cases, the cylindrical member comprises one, two, or more discrete pieces. In some cases, a flange extends horizontally from the bottom of the cylindrical member, to be disposed at a bottom portion of the carrier bar. In some cases, the cylindrical member comprises a slit that extends from the top to the bottom of the cylindrical member to allow the member to be opened and to receive the polished rod. Additional implementations are described.

A method for forming a guide for a top drive unit includes connecting a lower track member to a lower mast section and connecting an upper track member to an upper mast section and telescoped with the lower track section. A slider is slidably positioned about the upper track member so the slider is movable along the upper track member. The slider has a lateral cross-sectional profile substantially the same size and shape as a lateral cross-sectional profile of the lower track member. The skate is slidably positioned about the lower track member to be movable along the lower track member and onto the slider. The skate travels along the upper track member via the slider. The skate is connectable to a top drive unit so the top drive unit is movable along the lower track member and the upper track member.

A method for installing pipeline segments within a conduit. The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

A control line clamp comprising a clamping element for retaining one or more control lines alongside a pipe; a first collar; and a second collar, wherein the clamping element is arranged to be attached to the pipe by positioning the first and second collars around the pipe on opposing sides of the clamping element and moving the first and second collars relatively towards each other in an axial direction.

Centralizers for stabilizing production tubing within a well may include a mandrel for securing within a section of production tubing and having a gland mounting surface; a gland mounted to the gland mounting surface of the mandrel, and having a cylindrical body and two or more lobes extending radially outward from the cylindrical body and comprised of an abrasion resistant material. Downhole assemblies may include a production string receivable within a cased well; a tubing anchor catcher positioned within the production string; a downhole pump coupled to the production string and located axially below the tubing anchor catcher; and a centralizer coupled to the production string.

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 guide mechanism may include a first jaw and a second jaw pivotably coupled to the first jaw. The jaws may include a guide having a bottom pocket for seating arrangement on a box end of a first tubular and a top funnel for laterally guiding a pin end of a second tubular into the box end. The guide mechanism may also include a linkage system secured to the first and second jaws to control pivoting motion of the jaws. The guide mechanism may also include a bias mechanism coupled to the linkage system and configured to impart a biasing force on the jaws via the linkage system. The biasing force may be adapted to resist opening of the jaws such that opening of the jaws occurs when a lateral force is applied to the guide mechanism that overcomes the biasing force.
