International Classification:

E21B 23/00

E21B 19/00

US Classification:

166382, 166 781, 166 68

Abstract:

A rotating breech lock rotates tubing to distribute wear caused by a rotating or reciprocating rod of an artificial lift system. The rotating breech lock has a spool that disposes on a wellhead. A bowl element disposes in the spool's bore, and a hanger fits into the spool and lands on the bowl element with a thrust bearing. Above the hanger, a load ring fits against the hanger with a bearing, and a hold-down sleeve and locking pins hold the load ring against the hanger. The spool has a worm that mates with a wheel defined about the hanger so turning the worm by a ratchet or other mechanism rotates the hanger. Internally, the hanger has a bore with opposing shoulders separated by gaps. A mandrel couples to the tubing and disposes up into the hanger. Protrusions or keys on the hanger can selectively align with the gaps and the shoulders depending on how the mandrel is rotated in the hanger bore.

International Classification:

US Classification:

166345, 166368

Abstract:

A modular assembly for a wellhead has a housing and a plurality of modular cartridges. The housing connects with a studded or flanged connection to the wellhead, which can have a tubing adapter, casing hanger, etc. The modular cartridges can interchangeably stack in the housing's internal pocket so that the bores of the stacked cartridges configure the through-bore of the assembly communicating the wellhead with external components, such as flow lines, capillary lines, etc. The modular cartridges include a spacer cartridge, a hanger cartridge, a valve cartridge, and a cross cartridge. The spacer cartridge can be used to space other cartridges in the internal pocket, and the hanger cartridge can be used to support capillary strings and/or velocity strings in the wellhead. The valve cartridges have valve elements that can be opened and closed by bonnets that affix externally to the housing. The cross cartridge can have one or more cross ports to divert the assembly's through-bore to additional flow components, such as flow lines, wing valves, chokes, and the like.
