Abstract: Tools for sealing a tubing in a downhole environment. The tools feature top and bottom slip assemblies and a monolithic sealing element. The monolithic sealing element includes a portion that is disposed between the top and bottom slip assemblies as well as portions that encapsulate the slip assemblies. When the tool is actuated from a run-in configuration to a set configuration, the slips move toward each other squeezing the sealing element so that it forms a fluid-tight seal with the tubing. Teeth of the slip assemblies penetrate the portions of the sealing element disposed thereon and bite into the tubing.

Abstract: Degradable downhole tools, tool components, and balls are formed from a processed polyvinyl alcohol (PVA) compound that is degradable in a high-salinity environment. The PVA compound exhibits strength and elasticity properties that are comparable to existing degradable downhole polymers and further exhibits degradability properties that are superior to existing degradable downhole polymers, particularly in high-salinity fluids. For different components, the PVA compound may include a reinforcing material such as fiberglass. The PVA compound also includes a loading of degradable metal, such as a degradable magnesium alloy, rendering the material degradable at high salinity. Usage of tools, tool components, and balls formed from the disclosed materials eliminates the requirement that such equipment be drilled out after use as the PVA compound quickly degrades in high-salinity downhole fluids.

Abstract: Methods and systems for diverting the flow of fluids within a wellbore are disclosed. The methods and systems use a flow conveyed diverter pack, which includes a package portion and a wing portion. The package portion may contain a ball (a.k.a. a diverter ball) and may contain additional components. The diverter pack may be formed by sandwiching a diverter ball between films of a flexible material, for example, films of a dissolvable polymer. The diverter pack may be deployed in a wellbore, whereby the pack is conveyed by fluid flow to an opening to be sealed. The diverter pack seats upon the opening, thereby diverting flow from the opening.

Abstract: Dissolvable thread sealants are useful for forming a pressure-tight seal between dissolvable threaded components, particularly in downhole tools. A film of the dissolvable thread sealant can be formed on the threads of dissolvable threaded components. As the dissolvable threaded components are exposed to fluid under the appropriate conditions and begin to dissolve, the thread sealant becomes exposed to the fluid and, likewise, dissolves. Embodiments of the dissolvable thread sealants are made using polyvinyl alcohol (PVA).

Abstract: Degradable downhole tools, tool components, and balls are formed from a polyvinyl alcohol (PVA) compound. The PVA compound exhibits strength and elasticity properties that are comparable to existing degradable downhole polymers and further exhibits degradability properties that are superior to existing degradable downhole polymers. For different components, the PVA compound may include a reinforcing material such as fiberglass. A plug for use in a wellbore conduit may include a sealing element that is formed of PVA compounds of various types.
