Patent number: 10837250Abstract: 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.Type: GrantFiled: February 27, 2018Date of Patent: November 17, 2020Assignee: Weatherford Technology Holdings, LLCInventors: Todd Travis, Brandon M.

Patent number: 10196883Abstract: A long-stroke pumping unit includes a tower; a counterweight assembly movable along the tower; a drum connected to an upper end of the tower and rotatable relative thereto. The unit also includes a belt having a first end connected to the counterweight assembly, extending over the drum, and having a second end connectable to a rod string. The unit further includes a prime mover for reciprocating the counterweight assembly along the tower; a sensor for detecting sudden acceleration of the counterweight assembly due to failure of the rod string; and a controller in communication with the sensor and operable to activate the braking or arrestor system in response to detection of the sudden acceleration. The unit further includes at least one of a braking system for halting free-fall of the counterweight assembly; and an arrestor system for absorbing kinetic energy of the falling counterweight assembly.Type: GrantFiled: January 11, 2016Date of Patent: February 5, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Clark E.

Patent number: 10018008Abstract: On a wellhead, a well component, such as a casing head, has a bowl with a first shoulder and a groove defined therein. A hanger for supporting casing positions in the bowl, and a latch assembly on the hanger latches the hanger in the groove. The latch can have a traveling ring and a latch ring supported on the hanger's exterior surface. The traveling ring engages the first shoulder in the bowl and pushes the latch ring against a portion of the hanger, such as a second shoulder. The latch ring has a joint at a split in the latch ring, and the joint holds the latch ring in a compressed state about the exterior surface. When the latch ring moves with the engagement of the traveling ring against the hanger portion, the joint is disjointed, and the latch ring expands outward into the groove to latch the hanger in the bowl.Type: GrantFiled: August 6, 2014Date of Patent: July 10, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Brandon M.

Patent number: 9254528Abstract: A slip on nut and reverse cut die is provided for dressing the threads of a wellhead or other item. A nut is provided that may be slipped onto a threaded section, past any damaged threads, without engaging the threads of the threaded section. Once positioned on a threaded section the nut may be tightened as desired. When removing the nut the reverse edges of the nut may repair or even cut new threads into the threaded section.Type: GrantFiled: January 20, 2012Date of Patent: February 9, 2016Assignee: Weatherford Technology Holdings, LLCInventors: Brandon M.

Publication number: 20150114626Abstract: An object launching apparatus for a well has a housing, a flow mandrel, and a cage. The flow mandrel is disposed in the housing's internal chamber, and a flow passage in the mandrel communicates flow from the housing's inlet to the mandrel's flow port, which in turn communicates with the housing's outlet. The cage is disposed in the internal chamber and defines pockets for holding the objects. A motor and shaft move the cage in the housing relative to the mandrel's flow port so the cage's pockets can be selectively positioned in communication between the mandrel's flow port and the housing's outlet. This allows any of the object(s) held in the positioned pocket to be launched into the flow to the well. Preferably, the motor rotates the shaft so the cage can ride linearly along the shaft's thread and the cage can rotate through a cammed engagement with the housing.Type: ApplicationFiled: October 29, 2013Publication date: April 30, 2015Inventors: Adam J. Hatten, Eric Calzoncinth, Todd Travis, Brandon M. Cain

Patent number: 9009945Abstract: Hydraulic flange connectors connect two flange components together, and hydraulic pressure applied to ports in connector holes of one of the flanges tension the flange studs and crush the gasket between the flange components. Each connector has a piston that disposes in the connector hole and can move therein when hydraulic pressure is applied through the port by a pump. A first stud connected to the piston extends beyond one open end of the hole for connection to a first nut, while a second stud connected to the piston extending beyond another open end of the to the second flange component for connection to a second nut. A retainer having seals threads in this other open end of the hole and seals between the hole and the second stud.Type: GrantFiled: November 25, 2013Date of Patent: April 21, 2015Assignee: Weatherford Technology Holdings, LLCInventors: Todd Travis, Brandon M.

Patent number: 8763708Abstract: 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.Type: GrantFiled: October 12, 2010Date of Patent: July 1, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Todd Travis, Scott Menard, Brandon M.

Patent number: 8668020Abstract: An assembly supports a control line of a downhole tool, such as a downhole deployment valve. The tool deploys on casing and has a control line extending from the wellhead to the tool. To support the line separately from any casing hanger, a split bowl disposes around the casing and lands on a shoulder in the head. A port in the bowl has one opening that aligns with a side port in the head. Another opening of the bowl's port connects to the control line that extends to the downhole tool. A section of the control line from the split bowl can be flexible to help prevent kinking or breaking of the line during installation procedures. A hanger disposes on another shoulder in the head uphole from the bowl. The hanger supports the casing in the head separate from the bowl's support of the control line.Type: GrantFiled: November 19, 2010Date of Patent: March 11, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Genith del Carmen Guitierrez, Todd Travis, Brandon M.

Patent number: 8479824Abstract: A power slip extends a joint from tubing disposed in casing at a well so that a casing head can install on the casing and the tubing can be packed-off from the casing. The joint attaches to an inner sleeve having collet members that fit onto the inner tubing so that the joint extends thereabove. An outer sleeve and interlocking collet assemble together and install onto the inner sleeve. The collet threads onto the inner sleeve and forces the outer sleeve downward onto the inner sleeve. Being forced, the outer sleeve causes the collet members to engage around the inner tubing. The casing head then installs on the casing with the joint extending up through the head's bowl. An H-plate installs in the open bowl around the extended joint, and another pack-off installs on the joint to pack it off from a spool attaching to the casing head.Type: GrantFiled: September 23, 2009Date of Patent: July 9, 2013Assignee: Weatherford/Lamb, Inc.Inventors: Todd Travis, Elizabeth A.
