Benefits of technology
The invention is a device called a blowout preventer (BOP) that is used to control pressure in a wellbore. The BOP has an internal cavity and a front side with a door opening, which is connected to a door assembly. The door assembly includes a door that can be moved between two positions: one that blocks access to the internal cavity and one that enables access. The door assembly also has a hinge to make it easy to move the door. The BOP also has an outlet on the back side that is connected to the internal cavity. The technical effect of the invention is to provide a reliable and effective way to control pressure in a wellbore.
Problems solved by technology
The shear rams within the BOPs may undergo maintenance operations, and installation and removal may be time consuming and dangerous due to the configuration of many BOPs.

A blowout preventer (BOP) for controlling pressure within a wellbore includes an internal cavity and a front side including a door opening, the door opening providing access to the internal cavity. The BOP also includes a door assembly associated with the door opening. The door assembly includes a door, movable between a first position and a second position, the door blocking access to the internal cavity in the first position and enabling access to the internal cavity in the second position. The door assembly also includes a hinge coupled to the door to facilitate movement of the door between the first position and the second position. The door assembly further includes a coupling device associated with the door, the coupling device securing the door to the front side. The BOP also includes a back side including an outlet, the outlet being fluidly coupled to the internal cavity.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is related to U.S. patent application Ser. No. ______, filed Aug. 27, 2019, titled “BLOWOUT PREVENTER SYSTEM AND METHOD,” the full disclosure of which is hereby incorporated by reference in its entirety for all purposes.BACKGROUND OF THE DISCLOSURE1. Field of the Disclosure[0002]This disclosure relates in general to oil and gas tools, and in particular, to systems and methods for sealing across lines or pipes.2. Brief Description of Related Art[0003]In oil and gas production, drilling and recovery may occur in high pressure environments where various tools may be utilized to control wellbore pressures. For example, a blowout preventer (BOP) or the like may be arranged at an entrance to the wellbore. During operations, equipment may pass through the blowout preventer and, if necessary, the blowout preventer may be utilized to seal the wellbore to reduce the likelihood of uncontrolled releases from the wellbore. One compone...
