Blow Out Preventer Or Choke Valve Device (e.g., Oil Well Flow Controlling Device, Etc.) Patents (Class 137/315.02)
  • Patent number: 9752405
    Abstract: An angle-cut shear ram blowout preventer system containing an angle-cut shear ram inside a ram housing with a ram housing bore. A ram cylinder pressure housing can be secured to the ram housing, wherein the ram cylinder pressure housing can be fluidly connected to a hydraulic pressure source or a pneumatic pressure source. A piston in the ram cylinder pressure housing can be fluidly connected to the hydraulic pressure source or the pneumatic pressure source. A taper can be extended from the ram housing bore into a through bore to simultaneously sever a pipe in a well and seal the well once the pipe is severed without requiring additional downhole tools.

  • Patent number: 9022103
    Abstract: A capture device for a bore hole of a fluid source, has a base plate (6) that can be anchored at the floor, over the bore hole, and has a bore hole opening (8) through which fluid can be streamed out of the bore hole. An ascending pipe (2) is arranged over the bore hole opening (8). Guide baffles (9) are arranged around the bore hole opening (8), and have blades (10) fixed to the top of the base plate (6) so that the guide baffles (6) can be pivoted and displaced. The blades (10) encompass the longitudinal end (3) of the ascending pipe (2) that faces the bore hole opening (8) like a flower and overlap one another, whereby fluid flowing from the bore hole opening (8) can be captured via the blades (10) and discharged to the ascending pipe (2).

  • Patent number: 8622139
    Abstract: Wellhead-based systems, apparatus, and methods for controlling a well are provided. During a failure of an emergency system such as a blowout provider, a wellhead based emergency control apparatus according to an embodiment of the invention can be employed to control the well. A casing strings compression assembly can radially compress each of the casing strings and/or drilling pipe extending through the wellhead housing to restrict or stop well fluid passage. A casing strings penetrator of an emergency well fluid diversion assembly can also or alternatively be employed to form an aperture in the casing strings. A diverter, integral with or connected to the penetrator, is extended through an aperture in a side of the wellhead housing and one or more of the apertures cut by the penetrator to divert well fluid from within the wellhead housing through a passageway in the diverter and to an external conduit.

  • Publication number: 20090095464
    Abstract: An apparatus to allow backup or alternate fluid flow routes around malfunctioning BOP control components using a remotely installed removable hydraulic hose connection. The backup fluid flow route sends pressure-regulated hydraulic fluid to a BOP operation via an isolation valve rigidly attached to the BOP, then to a hose connected to an intervention panel on the BOP and finally through a valve that isolates the primary flow route and establishes a secondary flow route to allow continued operation. To increase reliability, the backup components route from a spare BOP function and are rigidly fixed to the BOP.
