An adjustable release pressure relief valve including a housing having an inlet and a relief outlet connected by a fluid flow passageway, the inlet fluidly connectible to a work string. A head is sealingly disposed within the passageway between the inlet and relief outlet closing the fluid flow passageway between the inlet and relief outlet. An elongate buckling rod supports the head and is bucklable at a predetermined load thereby permitting sliding of the head from between the inlet and a relief outlet and opening the fluid flow passageway. A lateral support projection is extendable within the housing to buttress the buckling rod along the longitudinal length of the buckling rod thereby increasing the load at which the buckling rod is collapsible.

System for electrically grounding a reusable load-supporting surface includes at least two mats and a plurality of substantially planar, removable, electrically-conductive covers. Each cover extends at least partially across the top face of one of the mats without extending over any of the edges thereof and is flexibly coupled to the mat sufficient to allow the mat to flex, expand and contract relative to the cover due to environmental factors and the movement of personnel, vehicles and/or equipment across the load-supporting surface during normal, typical or expected use conditions.

A relief well injection spool for use in killing a well has a body with a pair of inlets opening to a bore on an interior of the body, a ram body cooperative with the bore of the body so as to selectively open and close the bore, an upper connector affixed to the body and adapted to connect the body to a lower end of a blowout preventer, and a wellhead connector affixed to a lower end of the body. Each of the pair of inlets has a valve cooperative therewith. The upper connector opens to the bore of the body. The wellhead connector is adapted to connect to a relief well wellhead. The wellhead connector also opens to the bore of the body. A floating vessel can be provided so as to deliver a kill fluid into at least one of the pair of inlets.

Methods and apparatus are disclosed for retaining components in a downhole motor in the event of a mechanical separation or failure of one or more components therein. As described, the retention mechanism does not require a threaded connection to components of the mud motor drivetrain. Downhole motor assemblies including the new catch mechanism also include a structural element to engage the catch assembly and the components to which it is attached in the event of a mechanical failure within the mud motor assembly.

A safety-harness attachment for attaching a safety harness thereto.

Technologies are generally described for apparatus, systems, and methods to reduce cost and simplify couplings for wellhead equipment and related cable assemblies. The wellhead equipment is placed on a well that is bored into the ground. The wellhead cable may employ a splice assembly that includes a downhole cable, a surface cable, and a conduit. The surface cable is spliced with the downhole cable below a wellhead hanger. The conduit may be configured to contain the surface cable and terminate in the explosion-proof conduit box located at the surface. An inner space of the conduit may be sealed below the wellhead hanger. The conduit may be break-free, or contiguous, between the wellhead hanger and the explosion-proof box.

Computer vision drilling systems and methods may be used with a drilling rig. The computer vision systems and methods may be used during drilling of a well to monitor the drilling equipment and personnel on the drilling site to provide safer drilling operations. The results from the computer vision drilling system may be used to cause corrective actions to be performed if a safety condition arises. In addition, computer vision systems and methods are provided to automatically monitor the drilling site and drilling operations, such as by tallying pipe in the drill string and by monitoring equipment for anomalous drilling conditions, and automatically taking corrective action as may be needed.

The present invention relates to a downhole packer assembly for expansion of a metal sleeve, such as a metal patch, in a well downhole in a well tubular metal structure, the well having a top comprising a body part having an axial extension, a first end facing downhole and a second end facing uphole towards the top of the well, an expandable tubular packer element surrounding the body part, and a first end and a second end of the expandable tubular packer element are fixedly connected with the body part, providing an expandable space therebetween, the expandable space being fillable with liquid during expansion, and a metal sleeve surrounding the expandable tubular packer element, wherein the downhole packer assembly further comprises a restriction unit comprising an axially movable part, the axially movable part having a first part end facing the first end of the expandable tubular packer element and a second part end facing away from the expandable tubular packer element, the axially movable part having a first axial position in which the axially movable part at least partly overlaps the expandable tubular packer element and a second axial position in which the axially movable part has been axially displaced in relation to the body part away from the expandable tubular packer element. The invention also relates to a downhole system comprising the downhole packer assembly and a driving unit, such as a downhole tractor, for propelling the downhole packer assembly in the well tubular metal structure.

A safety plug for use in a bore hole comprising a bore wall. The safety plug comprises a body having a leading end and a trailing end, and at least one flared portion. An anchoring element extends at least partially around an associated flared portion. Axially displacement of anchoring element relative to its associated flared portion causes the anchoring element to bear against the flared portion and transitions the anchoring element between an unexpanded condition and an expanded condition. A nose, comprising conical elements, extends longitudinally from the leading end of body. The nose is longitudinally compressible.

A selection of a hydrocarbon well of a hydrocarbon production system is received at a safety logic solver (SLS) for proof testing. Test mode pressure sensors attached to a common header of the hydrocarbon production system are activated to monitor a live process condition status of the common header from all wells of the hydrocarbon production system. A simulated overpressure condition is induced in the operation pressure sensors. An indication of overpressure is received at the SLS from at least two operation pressure sensors. Final elements associated with the hydrocarbon well are signaled to close while leaving other wells in the hydrocarbon production system in operation. The operation pressure sensors are restored to a normal pressure condition, and the final elements associated with the selected hydrocarbon well are signaled to re-open the hydrocarbon well.
