摘要： A ball injector for connecting below the frac head of a frac tree to accommodate and sequentially drop a ball into the axial passageway of the frac tree. The ball injector has an axial passage of an injector housing aligned with the axial passageway of the frac tree. A ball cartridge assembly stores one or more balls and sequentially delivers one ball to a port in the ball cartridge assembly. A ball launch side arm extends from the injector housing and forms a ball launch passageway communicating between the ball cartridge port and the axial passage. A first valve member in the ball launch passageway is opened to pass the ball into the axial passage, and is closed to isolate the ball cartridge assembly from a pressure in the axial passage. A second valve member between the first valve member and the ball cartridge assembly may be included to form a pressure isolation chamber between the valve members. Embodiments of ball cartridge assemblies to horizontally store a plurality of balls is provided. Also provided is a method of delivering a ball into a frac tree below the frac head, and a method of delivering and monitoring a ball progression into the frac tree, for example with a camera.

摘要： An expanding gate valve and method is provided for bidirectional sealing capability against pressure, whether the direction of pressure is upstream or downstream. The bidirectional annular seat seals against the gate assembly against pressure from the normal wellhead direction, typically upstream. For sealing against pressure in the opposite direction, the seat is formed with an annular recess extending radially outwardly from the central bore of the annular seat so that a flex portion of the seat formed between the recess and the front sealing face of the annular seat at the central bore flexes toward the gate assembly against this pressure. The front face of the bidirectional seat forms a raised annular sealing portion on the flex portion of the seat adjacent the central bore to provide sealing contact with the gate assembly in the expanded condition when the flex portion flexes toward the gate assembly.

摘要： A system and method for locking together a running tool and a tubular member to rotate the tubular member. The system includes a tubular member and a running tool adapted to engage in a mechanical connection such that the running tool and the tubular member are arranged concentrically and moveable longitudinally together. The system includes a locking assembly adapted to lock the tubular member and the running tool together once the tubular member and the running tool are engaged in the mechanical connection, so that torque applied to the running tool is applied to the tubular member through the locking assembly to rotate the running tool and the tubular member synchronously. The locking assembly is adapted to unlock the tubular member and the running tool when the tubular member is landed on a shoulder of an outer tubular member so that the mechanical connection can then be disengaged.

摘要： A ram type blowout preventer having a seal on each ram, extending across the front face, rearwardly and then over the top portion or the bottom portion of the ram. Each ram forms a leading edge portion above or below the front face seal, so as opposing rams move into the extended sealing position, the leading edge portions of the rams press against each other, imparting a generally vertical movement to bring the seals on the front faces into sealing engagement with each other and to energize the seals extending over the top or bottom portions against the ram bores. The front face of each ram may include a portion which is inclined toward the central bore. Rope packing seals may be provided on the rams having a vertical offset at the front faces of the rams such that rope packing seals on opposing front faces seal against each other.

摘要： The invention broadly provides a ram incorporating a thermoplastic seal for sealing in the horizontal bore of a wellhead production blowout preventer to close off the vertical bore of the well, the ram being adapted to seal at its front end against either a polish rod of a rod string, or against an adjacent ram. The invention also extends to a BOP including a pair of such rams, wherein, each ram includes (a) a body component with front and rear portions and ends, (b) a seal component with front and rear portions and ends, (c) the body component having an arcuate longitudinal outer surface for conforming with the horizontal bore surface, and having a cut-out in its front portion which provides a seal support surface to support the seal component in both a vertical and horizontal direction, (d) the seal component having an arcuate longitudinal outer surface for conforming with the horizontal bore surface, and an inner surface which generally conforms to the seal support surface of the body component, the body component and seal components combining, in an assembled form, to form a full bore ram body, which when out of sealing engagement has the front end of the seal component protruding a horizontal distance d beyond the front end of the body component, (e) connectors for connecting the seal and body components while allowing the seal component, during sealing engagement, to be pressed against the seal support surface of the body component, and (f) the seal component providing a sealing surface formed of thermoplastic material around the arcuate outer surface for sealing against the horizontal bore. Thus, as the body component is advanced forwardly into a sealing engagement causing the front end of the seal component to contact either the adjacent ram or the polish rod to seal off the vertical bore, the seal component is pressed against the seal support surface of the body component such that the thermoplastic sealing surface is compressed outwardly to seal against the horizontal bore.

摘要： A method and fluid connection system to fluidly connect a fracturing manifold to a fracturing tree. The method includes fluidly connecting a plurality of flexible flowlines between the manifold outlet of a fracturing manifold module and the fracturing tree such that fluid from the manifold outlet is distributed into the flexible flowlines and into the fracturing tree to avoid abrupt or right angle changes in direction in all fluid connections at the fracturing tree and between the manifold outlet and the fracturing tree. The fluid connection system includes a flow distribution block having a single inlet and a plurality of outlets, and distributes fluid flow between the single inlet and the plurality of outlets without abrupt or right angle changes in direction. The flexible flowlines have a first end fluidly connected to one of the plurality of outlets, and a second end fluidly connected to the fracturing tree.

摘要： The invention provides a casing adapter tool which connects and seals to a casing pipe at its lower end and to production or service equipment at its upper end, and is used with well servicing equipment, such as is involved in fracturing. The casing adapter tool includes a generally tubular casing adapter body having an upper end and a lower end, and is formed with a central bore extending therethrough. The central bore provides a profile which forms a casing seal chamber at the lower end, and a barrier seal chamber located thereabove. The barrier seal chamber is formed with a profile to accommodate and seal to a first removable pressure barrier on removal of any well servicing equipment. Most preferably, the barrier seal chamber has a profile sized to provide full bore access to the casing pipe and to accommodate and seal to the first removable pressure barrier which is of a threaded, latched or snap ring type check valve or plug. The casing adapter body may also form a fracturing seal chamber in the central bore above or below the barrier seal chamber, with a profile to permit a fracturing isolation tool to be run in and sealed against the central bore. The casing adapter tool preferably includes a tubing hanger portion at its upper end, such that the tubing hanger can provide a second barrier, such as a check valve. The casing adapter tool thus provides a quick connection, seals and full bore access to the casing pipe. Once all well servicing equipment is removed, the casing adapter tool remains on the well and provides at least one and preferably two independent barriers between the well bore pressure and the atmosphere.
