A borehole tool including a unitary, single-piece basepipe having a first end portion, a second end portion, and an intermediate portion between the first end portion and second end portion, the first and second end portions being of larger diameter than the intermediate portion, an operational member having a first end and a second end, the member disposed about the basepipe, the member having an outside diameter no greater than the first end portion and the second end portion. A method for making a screen including wrapping a wire around the basepipe, and forming the filtration media with the wire. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and a tool disposed within or as a part of the string.

A hydraulic fracturing tree wing is formed with a studded hydraulic valve next to a manual valve. The stud-to-flange connection allows for a shorter, lighter wing. The studded hydraulic valve maybe a gate valve that includes a T-slot coupling between an operating stem and the gate. A bonnet seal ridge may be formed to withstand undue deformation during operation that wears or destroys seals. A method for forming a hydraulic fracturing tree assembly includes using a flanged manual valve with a studded hydraulic valve. Other valves and methods are presented.

A system is provided that include a safety device configured to mount in a mineral extraction system and block axial movement of a plug in the mineral extraction system while the plug is released from a retainer. The safety device may be a sleeve configured to receive screws or other retention mechanism in a tubular. A method is provided that includes installing a plug safety catch into a tubular of a mineral extraction system in which the plug safety catch is configured to block axial movement of a plug in response to a pressure differential while the plug is released from a mount position.

A system is provided that can include a rotating control device (RCD) with a sealing element and a force measurement device for measuring an axial force imparted to the sealing element. The system can also include a computing device that is communicatively coupled to the force measurement device for receiving the axial force measurements and from which the wear status of the sealing element can be determined.

A well casing security device and method. The security device includes a cover including a sidewall, a top, one or more stabilizers, and a means for attaching the cover to a well casing or to its concrete slab to render it vandal-resistant. A locking support ring is provided for attachment to either the well casing or to the concrete slab surrounding the casing. The locking support ring includes a ring body with a plurality of braces. Each of the braces includes an arm defining a slot between the arm and the ring body. The cover includes a plurality of brackets enabling rotational engagement cover with the locking support ring. Locking means are provided on the cover to lock the cover to the locking support ring. The locking means includes a key operated lock that is tamper resistant and insures that the well casing cannot be accessed easily by an intruder.

A hydrated inorganic oxide material capable of elongating from a planar shape to a fiber shape along a thickness direction of the planar shape, wherein the fiber shape is at least about 25 times greater in the thickness direction than the planar shape, and wherein during elongating a radial dimension of the hydrated inorganic oxide material changes by less than about 10% may be useful in a plurality of wellbore operations. For example, a method may include introducing a wellbore fluid comprising an aqueous base fluid and a hydrated inorganic oxide material into a wellbore penetrating a subterranean formation; and swelling the hydrated inorganic oxide material by contacting the hydrated inorganic oxide material with a polar amine compound such that the hydrated inorganic oxide material elongates from a planar shape to a fiber shape along a thickness direction of the planar shape.

A system and method for covering a cellar at a wellhead to prevent and control fluids and gases from the cellar. The covering includes a mat that circumscribes a wellhead tubular that projects upward from the cellar. A split seam in the mat extends radially from the opening to the mat outer periphery which allows the mat to be placed around the wellhead tubular. A fastener joins the ends of the mat that meet at the split seam. The mat includes a collar, which mounts to the mat along the opening and extends axially away from an upper surface of the mat. The collar is secured to the wellhead tabular with a strap. Two discharge lines project through the mat into the cellar, one for pumping into the cellar, and one for withdrawing fluid that has collected in the cellar.
