Side packer for a blowout preventer
The present disclosure relates to a system that includes a ram configured to mount in a blowout preventer. The ram includes a packer assembly configured to form a seal between the ram and a bore formed through the blowout preventer and an insert of the packer assembly, where the insert is coupled to a surface of the ram via a key-slot interface.
TEMPORARY SUSPENSION OF COMPLETED HYDROCARBON WELLS
In the process of suspending a subsea hydrocarbon well (1) after finalizing the completion operation and prior to stimulation of the well and putting the well on production, preinstalled upper and lower glass plugs (11, 12) are used as temporary barriers in the tubing. The plugs allow various tests to be performed before the lower plug (12), below the production packer (10), is broken; the upper plug (11) located above the downhole safety valve (13) then forms one of the barriers required to suspend the well whilst the Blow Out Preventer (BOP) is removed and Xmas tree installed, at which point the upper plug (11) is broken.
INTERLOCK FOR A DRILL RIG AND METHOD FOR OPERATING A DRILL RIG
An interlock between a drawworks and a blowout preventer includes a sensor for sensing a position of the blowout preventer. An interlock signal is generated by the sensor, and the interlock signal is reflective of the position of the blowout preventer. A lock operably connected to the drawworks receives the interlock signal and disables operation of the drawworks if the interlock signal meets a predetermined criterion. A method for operating a drill rig includes operating a drawworks to raise and lower a drill string and operating a blowout preventer. The method further includes sensing a position of the blowout preventer and generating an interlock signal that reflects the position of the blowout preventer. The method further includes comparing the interlock signal to a predetermined criterion and disabling the drawworks if the interlock signal meets the predetermined criterion.
High pressure blowout preventer system
A blowout preventer system including a lower blowout preventer stack comprising a number of hydraulic components, and a lower marine riser package comprising a first control pod and a second control pod adapted to provide, during use, redundant control of hydraulic components of the lower blowout preventer stack where the first and the second control pods are adapted to being connected, during use, to a surface control system and to be controlled, during use, by the surface control system. The blowout preventer system further including at least one additional control pod connected to at least one additional surface control system and to be controlled, during use, by the additional surface control system.
SHEAR RAM FOR A BLOWOUT PREVENTER
The present disclosure relates to a ram system for a blowout preventer. The ram system includes a first ram having an interlocking arm, where the interlocking arm includes a first anti-deflection feature. The ram system includes a second ram having a second anti-deflection feature. The first ram and the second ram are configured to move toward one another along a longitudinal axis to reach an engaged configuration. The second ram is configured to receive the interlocking arm of the first ram to enable the first anti-deflection feature to engage with the second anti-deflection feature while the first ram and the second ram are in the engaged configuration to thereby enable the first and second anti-deflection features to block deflection of the interlocking arm relative to a lateral axis, an axial axis, or both.
Hot isostatic pressing (HIP) fabrication of multi-metallic components for pressure-controlling equipment
A multi-metallic pressure-controlling component and a hot isostatic pressure (HIP) manufacturing process and system are disclosed. An example multi-metallic component for use in the oil field services industry includes a first metal alloy that forms a first portion of the multi-metallic pressure-controlling component, and a second metal alloy that forms a second portion of the multi-metallic pressure-controlling component. A diffusion bond is disposed at an interface between the first metal alloy and the second metal alloy that joins the first metal alloy to the second metal alloy within the multi-metallic pressure-controlling component.
Electrohydraulic system for use under water, comprising an electrohydraulic actuator
An electrohydraulic system for use under water includes an electrohydraulic actuator and a container. A hydraulic cylinder or a hydraulic motor and a hydraulic machine are arranged in an internal space of the container. The hydraulic machine is mechanically coupled to a rotary drive unit for a common rotary movement, and the hydraulic machine adjusts the hydraulic cylinder or the hydraulic motor. The rotary drive unit is arranged outside the container and is configured to couple to and decouple from the hydraulic machine. A device in one embodiment includes the electrohydraulic system.
HARDFACED METAL SURFACE AND METHOD OF MANUFACTURE
An apparatus is disclosed as including a first material volume with at least a hardened portion and a second material volume that includes at least two layers. The first material volume is composed of at least a hardenable alloy of steel. The at least two layers is located adjacent to a first surface comprising the hardened portion of the first material volume. The at least two layers includes a first layer composed of at least a ductile low-carbon alloy of steel and a second layer composed of at least a cobalt-based hardfacing over the first layer. The apparatus is applicable in preparing shear ram blocks and shear ram blades to provide a hardened blade edge with an adjacent hardfacing surface.
PISTON AND GATE ASSEMBLY FOR KINETIC PRESSURE CONTROL APPARATUS RAM
A ram for a blowout preventer has a pressure chamber having a piston movably disposed therein, and a charge disposed at one end of the pressure chamber. A gate is coupled to the piston on a side opposed to the charge. The gate is arranged to move across a through bore in a housing disposed at an opposed end of the pressure chamber. A coupling between the piston and the gate has sufficient strength to transfer kinetic energy of the gate to the piston.
Blowout preventer system and method
A blowout preventer (BOP) for controlling pressure within a wellbore includes a body having a front side and a back side, the front side being opposite the back side. The BOP also includes a door opening extending through the front side. The BOP further includes an operator opening extending through the body, perpendicular to the door opening. The BOP includes an outlet extending from an inner cavity of the body through the back side, the inner cavity being fluidly coupled to both the outlet and the door opening. The BOP also includes a ram passage forming at least a portion of the inner cavity, wherein the ram passage is arranged substantially perpendicular to the door opening.
