Abstract: A wellbore protector ram device includes a plurality of blocks that move in a plane orthogonal to an extension direction of a drill string and block junk from passing through a body of the wellbore protector ram device. The wellbore protector ram further includes a plurality of pistons that actuate, thereby locking and preventing movement of the plurality of blocks, and a plurality of springs that press the plurality of blocks against the drill string when the plurality of blocks are unlocked. The body includes an opening and encases the plurality of pistons and a plurality of springs. The drill string passes through the opening of the body.

Abstract: A sprinkler fitting configured to attach multiple sizes of sprinklers and possibly multiple sizes of flexible tubing. The sprinkler fitting has at least one end having two different sized threaded connectors configured to attach to different sized female sprinkler openings. A smaller connector is located distal on the end from the larger connector such that when the sprinkler fitting is attached to sprinkler head with a female opening having threads that correspond to the threads of the larger connector, the smaller connector is positioned without attachment to any threads within the female opening of the sprinkler head. The sprinkler head connector has at least a first connector and a second connector to attach multiple sizes of sprinklers. If included, the flexible tubing fitting connector has at least a first connector and a second connector to attach multiple sizes of flexible tubing.

Abstract: The embodiments herein provide a device for sealing an interface having an opening for a wire to pass through the interface. A pair of sealing blocks may be used where one block contains a protrusion and the opposing block contains a recess. The protrusion and recess preferably have an apex with a round having approximately the same dimension as the radius of the wire. A pair of posts may be positioned on opposing sides of the opening. One sealing block may contain an aperture for accepting one of the posts while the second sealing block may contain an aperture for accepting the opposing post. The posts may be threaded so that they can accept a threaded fastener. Exemplary embodiments may utilize mounting plates which may contain a flange such that squeezing the opposing flanges together can cause inward forces on the sealing blocks.

Abstract: A technique enables control over anti-extrusion layer movement during packer inflation. A packer employs a packer nipple having an exterior which uniquely engages distinct layers of the packer. The exterior comprises a plurality of distinct retention features, and each retention feature is designed to engage a specific layer of the packer. An individual retention feature can be uniquely designed to secure an anti-extrusion layer.

Abstract: A system and method for replacing equipment at a wellsite is provided. The wellsite has a subsea stripper installed proximate a subsea borehole. The system has a conveyance for delivering a BHA into the subsea borehole. The system has a subsea stripper having a central bore for passing the conveyance and the BHA therethrough, and at least one actuator connected to the subsea stripper for actuating a packer whereby the wellbore is sealed. The system has at least one replaceable seal assembly for installation within the stripper. The replaceable seal assembly has at least one packer extendable within the subsea stripper to form a seal thereabout and at least one locator sleeve for positioning the seal assembly in an install position within the subsea stripper. The replaceable seal assembly has a frangible member for connecting the seal assembly to the conveyance prior to deployment in the subsea stripper.

Abstract: A wellhead or Christmas tree seal assembly that forms a metal-to-metal seal between inner and outer wellhead or Christmas tree members. U-shaped metal seals having legs that face in opposite directions, are bonded to a wiping element. During installation of the seal assembly, the ends of the seal legs seal against the wellhead members and the wiping element compensates for defects on the surfaces of the wellhead members. The wiping element can be of an elastomer, metallic, or intercalated graphite material.

Abstract: An upper stripper rubber canister apparatus has a canister body and a canister body lid. An upper end portion of the canister body includes a breech lock structure exposed within the canister body central passage. A lower end portion of the canister body lid is configured for fitting within the central passage of the canister body. The canister body lid includes a breech lock structure that is configured for allowing the canister body lid to be fixedly engaged with the canister body by inserting a lower end portion of the canister body lid into a canister body central passage and rotating the canister body lid with respect to the canister body such that at least a portion of the canister body breech lock structure become at least partially overlapped with a respective one of the canister body lid breech lock structure.

Abstract: In a stripping arrangement for preventing liquid from penetrating at the peripheral gap (1) between a reciprocating component (2) and a casing opening (3) surrounding the latter, a choke ring (8) is provided on the side facing the inlet of the liquid to be stripped in the stripping bushing (4) in addition to at least one stripping ring (5) arranged in a stripping bushing (4), wherein this choke ring is designed with a smooth annular surface (9) on its front side facing the inlet of the liquid, and adheres to the smooth inner front surface (10) of the stripping bushing (4) facing it, exposed to the adhesive forces (S1) in the liquid. In this way, a significant path of entry for the liquid to be stripped into the stripping bushing (4) is blocked, so that the stripping ring (5) has to strip substantially less liquid from the reciprocating component (2).
