摘要： A treatment system including a settable and unsettable seal sub, an operation sub connected to the seal sub, the operation sub including a flow restrictor, and a selectively openable port biased to a closed position. A borehole system including a slickline, and a resettable seal connected to the slickline and runnable in the borehole on the slickline. A method for treating a formation adjacent a borehole including running the treatment system on a slickline to a target depth, flowing past the flow restrictor thereby causing the flow restrictor and a mandrel upon which the restrictor is mounted to move toward the seal sub, partially setting the seal sub and increasing pressure on the seal sub thereby fully setting the seal sub. A borehole system, including a borehole in a subsurface formation, a treatment system disposed within the borehole.

摘要： Systems and methods of the present disclosure relate to creating seals that expand during temperature drops. The seals may include a negative CTE material that is either internal or external to the sealing element; shape memory alloys (SMA) which exhibit negative CTE during a phase change; and/or external lattice structures with positive CTE components but negative overall CTE.

摘要： A well tool performs an operation in an oil/gas well. The well tool includes: a mandrel having a longitudinal direction and a radial direction perpendicular to the longitudinal direction; and an anchoring device for longitudinally locking the well tool to a bore including a lock groove. The anchoring device includes: a first ring arranged radially outside the mandrel; a second ring arranged radially outside the mandrel at a longitudinal distance from the first ring and movable in the longitudinal direction relative to the first ring; a spring element being substantially ring-shaped and arranged radially outside the mandrel; and a plurality of locking dogs distributed circumferentially on the spring element and located longitudinally between the first ring and the second ring. The anchoring device has a run state in which the first ring and the second ring are provided at an initial longitudinal distance from each other. The anchoring device has a set state in which the first ring and the second ring are provided at a shorter distance from each other, thereby wedging the locking dogs outwards in the radial direction. The spring element is configured to bias the locking dogs inwards in the radial direction towards the run state of the anchoring device.

摘要： A casing packer apparatus (P) comprising a mandrel (2) having a longitudinal throughbore, a packer element (6) mounted on the mandrel, and an expansion mechanism comprising a piston (11, 12) configured to move the packer element from a first position radially outwards to a second position. A bypass conduit (25) extends generally in said longitudinal direction, from one side of an outer sealing face of the packer element to an opposite side of the outer sealing face, and a bypass valve (41) controls said bypass conduit. The bypass valve is controlled by signals received via a wireless receiver (40). The casing packer can be deployed as an integral part of the casing string and used to control pressure build-up in the casing annulus.

摘要： A downhole plug (10) includes a mandrel (1) having a hollow structure, an annular sealing member (2) attached to an outer circumferential surface of the mandrel (1) and being deformable by exerted pressure, and an annular socket (3) attached, adjacent to the annular sealing member (2), onto the outer circumferential surface of the mandrel (1), downstream of where a pressure is exerted on the sealing member (2). The annular socket (3) is configured to include a socket-inner portion (31) which comes into contact with the outer circumferential surface of the mandrel (1), and a socket-outer portion (32) in an annular shape having an inner diameter equivalent to or larger than that of the socket-inner portion (31) and movably attached to the socket-inner portion (31). The socket-outer portion (32) includes a face facing the sealing member (2).

摘要： Systems and methods include a method for testing in a well. Inflow packers are run into a hole in locked position downhole. A liner top diagnostic tool is run on a drill pipe to a desired depth. A lower-packer-sized ball is dropped into the well to activate a lower inflow packer assembly. A back side of the lower inflow packer assembly is pressure-tested to ensure seal integrity. The lower inflow packer is unset by withdrawing string weight while rotating the string. The drill string is displaced to test fluid to the end of the string, and weight and rotation are applied again to set the lower inflow packer. A Homer plot is established based on an inflow test. A deactivation-sized ball is dropped to deactivate the lower include packer assembly. An upper inflow packer assembly is activated using upper-packer-sized ball. A leak is identified based on testing both liner tops.

摘要： A flow splitting device for gas reverse circulation drilling, including: an upper joint for connecting with a double-wall drill pipe; an inner tube which is arranged in the upper joint and defines a first passageway in communication with an inner chamber of the double-wall drill pipe, a second passageway in communication with an annular space in the double-wall drill pipe formed between the inner tube and the upper joint; a lower joint, having an upper end fixedly connected with the upper joint and a lower end for connecting with a drill tool; and a flow guiding member provided between the upper joint and the lower joint. A flexible sealing mechanism is provided outside the upper joint. The flexible sealing mechanism extends radially outward relative to the upper joint and the lower joint to form a sealing contact with a wellbore wall.

摘要： A back-up ring system incudes an outer C-ring, an inner C-ring that mates with the outer C-ring, the inner C-ring including a first rupture port, and a ring sheath that fits onto the inner C-ring, the ring sheath including a cut-out region, and a second rupture point. The inner C-ring further includes a blocking segment that angularly offsets the first and second rupture points. The cut-out region of the ring sheath mates with the blocking segment of the inner C-ring. The ring sheath further incudes a ‘7’ shaped cross-sectional profile.

摘要： Method of manufacturing a wellbore downhole tool, including providing a pre-polymer resin and processing the pre-polymer resin. Processing the pre-polymer resin includes applying directed energy from a directed energy source such that the pre-polymer resin is at least partially polymerized to form a polymer seal of the wellbore downhole tool, the polymer seal having one of more mechanical properties that differ along one or more dimensions of the polymer seal. A downhole tool for use in a wellbore, the downhole tool including a polymer seal. The polymer seal is a continuous single monolithic piece, includes polymer structures having a polymer chain including same types of monomers that are bonded together, and the polymer structures are altered along one or more dimensions of the polymer seal and one of more mechanical properties of the polymer seal differ along a same corresponding one of the or more dimensions of the polymer seal.

摘要： A frac plug is disclosed that is used for isolating a lower portion of a wellbore from an upper portion to enable a fracking process on newly created perforations in casing or liner pipe where the frac plug is particularly designed rapid drill out after all the fracking operations have been completed. The frac plug includes arrangements for holding the polymer or rubber element from rotation as the plug is being drilled. One arrangement includes pins that lock the polymer element to the bottom cone. In another, the polymer element is simply bonded by adhesive to the faceted cone. The facets on the cone prevent the cone from rotating in the wellbore by being pressed against the flat bottom slip segments that remain locked to the casing or liner pipe.
