A swivel joint includes a tubular female member which is rotatably connected to a tubular male member. The female member includes a female race portion having an axially extending inner annular recess, a female inner end portion which is formed at an axially inner end of the recess, and a number of inner annular grooves which are formed in the recess coaxially therewith. The male member includes a male race portion having an annular outer surface which is configured to be received in the recess, a male nose portion which is formed at an end of the male race portion, and a number of outer annular grooves which are formed on the outer surface coaxially therewith. The male race portion is positioned in the female race portion such that the male nose portion is located adjacent the female inner end portion and each outer groove is aligned with a corresponding inner groove to thereby define a number of annular bearing races within which a plurality of balls are received to thereby rotatably connect the male member to the female member. A first primary seal is positioned between the male nose portion and the female inner end portion, and a second seal is positioned between the male nose portion and the female inner end portion radially outwardly of the first primary seal. The male nose portion comprises an end wall which extends radially outwardly from the flow bore and a conical side wall which extends both radially and axially outwardly relative to the cylindrical side wall, and the second seal comprises at least a first portion which sealingly engages the conical side wall.

A connection assembly for automated lifting and positioning of a chiksan or other fluid conduit in proximity to a fluid inlet of a device such as, for example, a cement or hydraulic fracturing head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet including, without limitation, when the device is positioned at an elevated location above a rig floor.

A washpipe assembly for a power swivel and a power swivel incorporating the washpipe assembly. In an embodiment, the washpipe assembly includes a washpipe including a central axis and a radially outermost cylindrical surface. In addition, the washpipe assembly includes a first packing assembly configured to be coupled to a stem of the power swivel. The first packing assembly includes a seal assembly that includes one or more annular seal members each including a body and a contact insert mounted to the body, the contact insert engaging and forming a dynamic seal with the radially outermost cylindrical surface of the washpipe.

A fluid distribution system for a wellsite. The fluid distribution system may include a remote controller, a remote pump fluidly coupled to the first piece of wellsite equipment, and a remote fluid tank fluidly coupled to the remote pump. The first piece of wellsite equipment may include a local fluid tank comprising a fluid level sensor, a fill valve fluidly coupled to the local fluid tank, and a local controller configured to actuate the fill valve in response to a fluid level of the local fluid tank and to transmit at least one of a fill valve position or the fluid level of the local fluid tank to the remote controller. The remote controller may be configured to start and stop the remote pump in response to the transmissions from the local controllers.

A high pressure seal assembly for connection to an upper and lower connector pipe. The seal assembly includes a lower seal assembly surrounding a lower end of a rotating pipe, e.g., a washpipe. The lower seal assembly includes a first and second seal ring that define an annular space. The seal rings have a simple cross-section and are identical, thereby facilitating ease of manufacture and assembly. High pressure seals are received within annular spaces of the respective seal rings. The high pressure seals define inner surfaces that have a layer of self-lubricating polymer for engaging the rotating pipe. The high pressure seals define a pressure facing cavity that receives a high pressure ring that mitigates the spreading of the body of the high pressure seals due to pressure and that prevents the seal from extruding through an adjacent gap. An excluder seal prevents debris from entering the seal assembly.
