Blowout prevention (BOP) apparatus
The system is provided with a blowout preventer (BOP) positionable about the pipe and at least one seal assembly positionable about the BOP.
A blowout preventer (BOP) seal (102) and method are provided.
The BOP 28 is also installed at the upper end of the housing with a bore aligned with the wellhead housing bore.
After drilling the well, the casing string 19 carrying a casing hanger 42 may be lowered through the bores of the BOP, the spool tree, and the wellhead housing and into the well.
The worker will install the blow out preventer (14) on the pipe.
The method comprises the following steps: drilling of a first well; mounting and cementing of well pipes in the first well; mounting of a Blow Out Preventer or Lubricator in the top of the well.
One of the principal tasks the work vessel is designed to facilitate is the installation of a blow out preventer (14).
The blow out preventer (14) is designed to remove a section of the pipe and then to seal the severed pipe.
When restoration of flow is desired, the block (30) may be removed, allowing the blow out preventer to function as a valve.
Herein the blow-out preventer encloses the unexpanded tubular section and comprises a cutter (320) for cutting the unexpanded tubular section and at least one closure device (324) for closing the wellbore.
The subsea processor may be enclosed in a single interchangeable unit that fits a receptor on an underwater drilling component, such as a blow-out preventer (BOP).
The replacement blowout preventer system is coupled to the failed blowout preventer.
The blowout preventer console comprises a blowout preventer control panel (1).
The replacement blowout preventer system includes an hydraulic pressure source disposed proximate well closure elements on the replacement blowout preventer system.
A blow-out-preventer (24) is connected to the floating wellhead.
A lightweight blowout preventer having a low profile is disclosed.
A diverter system (10) for a subsea well has a blowout preventer (12) and a diverter (14) affixed to an outlet (20) of the blowout preventer.
A blowout preventer for sealing a tubular of a wellbore is provided.
An improved blowout preventor actuator (20) is provided for opening and closing a ram block (26) within a blowout preventor body (12) to control the flow of well fluid.
The inlet end of the flow passageway is suitable for connection to a blowout preventer or to a wellhead of a subsea well.
Apparatus and a method for killing a live well after activation of a well blowout preventer is described.
An improved blowout preventer for a well having a casing extending into an underground formation.
Techniques for shearing a tubular of a wellbore penetrating a subterranean formation with a blowout preventer are provided.
A method of locking a bonnet to a blowout preventer is also disclosed.
An underground annular blowout preventer assembly process is also provided.
The well closure elements on the replacement blowout preventer system are actuated using the hydraulic pressure source.
