Abstract: Manufacturing a dissolvable downhole hydraulic frac tool member, including providing water-soluble bulk metallic glass (BMG) particles, providing water-soluble thermoplastic polymer particles and mixing together to form a BMG-polymer blend. Heating the BMG-polymer blend to a temperature where the BMG particles are superplastic, the water-soluble thermoplastic polymer particles are moldable, and the BMG particles have a temperature of superplastic flowability that is in a moldability temperature range of the water-soluble thermoplastic polymer and are embedded in a matrix of the thermoplastic polymer to thereby form a BMG-polymer composition; and then;
forming the BMG-polymer composition into the frac tool member.-

Abstract: A swab resistant seal tool, includes a seal mandrel, a seal element, and a releaser securing the seal element to the mandrel under a tensile load. The releaser is releasable upon being exposed to a trigger. A method for assembling a swab resistant seal tool includes disposing a seal element on a mandrel, securing a first end of the seal element to the mandrel, imparting a tensile load to the seal element, and securing a second end of the seal element to the mandrel. A method for operating a seal tool includes resisting swabbing of a seal by holding tension in the seal element and setting the seal tool by releasing a releaser. A borehole system including a borehole in a subsurface formation, a string in the borehole, a seal tool disposed within or as a part of the string.

Abstract: A bellows assembly for a downhole tool includes a first seal ring, a second seal ring, and a bellows positioned at least partially between the first and second seal rings. The first seal ring, the second seal ring, and the bellows are integral with one another such that the bellows assembly is monolithic. The bellows is configured to expand and retract. The bellows is annular and has a diameter that varies over a length of the bellows. A material composition of the bellows varies over the length of the bellows.

Abstract: Fracturing systems with frac valves for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a bore to convey fracturing fluid, a seal disposed within the bore, and an actuator coupled to control movement of the seal. The actuator can be disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore. Additional systems, devices, and methods for fracturing are also disclosed.

Abstract: A device for wellbore operations is configured to self-determine its downhole location in a wellbore in real-time and to self-activate upon arrival at a preselected target location. The device determines its downhole location based on magnetic field and/or magnetic flux signals provided by an onboard three-axis magnetometer. The device optionally comprises one or more magnets. The magnetometer detects changes in magnetic field and/or magnetic flux caused by the device's proximity to or passage through various features in the wellbore. The device can self-activate to deploy an engagement mechanism to engage a target tool downhole from the target location. The engagement mechanism comprises a seal supported by two expandable support rings, each having a respective elliptical face for engagement with the elliptical face of the other support ring.

Abstract: A production well has nested casings including a first production casing and a first production tubing installed within the first production casing, which extends from a surface to a depth within the wellbore. Before implementing a gas-lift operation in the production well, the first production tubing is removed. A second production casing is lowered within the first production casing. The second production casing has a smaller outer diameter than an inner diameter of the first production casing. From the surface of the wellbore to the depth within the wellbore to which the second production casing extends, the inner diameter of the second production casing is expanded until an outer wall of the second production casing forms a gas-tight seal with an inner wall of the first production casing.

Abstract: A system includes a subsurface safety valve and a lock tool. The subsurface safety valve is installed within the production tubing and has a main bore delineated by an inner circumferential surface of the subsurface safety valve and a lock profile machined into the inner circumferential surface of the subsurface safety valve. The lock tool is movably disposed around a conduit and has a locking dog configured to engage with the lock profile of the subsurface safety valve and a conduit seal made of a swellable elastomer. The conduit seal is activated by an activation fluid and has an expanded position and an unexpanded position.
