Abstract: A downhole temporary pressure isolation tool configured to withstand very high gas pressures at high temperatures may be achieved by a variety of configurations, processes, and techniques. In particular implementations, a barrier valve having one or more frangible discs configured to resist fluid flow in a particular specified duration. In some implementations, the barrier valve may achieve a V0 rating. In one embodiment, for example, a barrier valve may prevent the passage of fluid (i.e., gas and/or liquid) at 15,000 psi and a temperature of 400 degrees F. for at least 15 minutes. If the barrier valve has two frangible ceramic discs, it may prevent the passage of fluid from two directions for at least 15 minutes.

Abstract: Downhole assemblies and methods for isolating a wellbore. A downhole tool can include a body having a bore or flowpath formed therethrough, and one or more sealing members disposed therein. The one or more sealing members can include an annular base and a curved surface having an upper face and a lower face, wherein one or more first radii define the upper face, and one or more second radii define the lower face, and wherein, at any point on the curved surface, the first radius is greater than the second radius. The sealing members can be disposed within the bore of the tool using one or more annular sealing devices disposed about the one or more sealing members.

Abstract: A downhole pressure isolation tool is disclosed for use in a tubing string or casing string. The tool includes a frangible disk or seal within a housing having a bore. The disk has a dome section and a cylinder section and the dome of the disk is transverse to the bore. A piston is located between the housing and the cylinder of the disk, the piston movable between a first position and a second position, the second position, engaging a set of fingers which push into the cylinder of the disc to break it, causing the entire disk the cause and the entire disk to fail. A rupturable membrane is provided which, when it ruptures places the piston in fluid communication with a fluid within the bore.

Abstract: A settable downhole tool with preset metallic split rings having gaps from their leading edges to their trailing edges. The rings expand radially outward during setting by widening the gaps, adjacent rings covering the gaps, creating a substantially fluid tight metal to metal seal with the casing.

Abstract: Downhole tools for use in oil and gas production which degrade into non-toxic materials, a method of making them and methods of using them. A frac ball and a bridge plug comprised of polyglycolic acid which can be used in fracking a well and then left in the well bore to predictably, quickly, and safely disintegrate into environmentally friendly products without needing to be milled out or retrieved.

Abstract: An electric setting tool powered through a cable or wire line for setting bridge plugs or other settable downhole tools and which may be used in conjunction with a select fire perforating gun. The electric setting tool is adapted to receive DC power and set a tool in the range of 20 to 60 seconds while operating at under 2.0 amps. The composite tool may be comprised of multiple perf guns subs, the electric setting tool, and bridge plug or other settable tool.

Abstract: A degradable downhole isolation tool for use in hydrocarbon well completion. The tool sets and isolates zones for fracking, and then degrades without leaving residual parts and without milling or introducing a new degrading fluid. The plug's mandrel and other parts are a solid polymer which hydrolyzes in aqueous downhole fluid to produce an acid which degrades degradable metal slips and other metal parts. The plug's seal may be degradable metal pedals or split rings. The plug is delivered to the well site as an interchangeable parts kit for adaption to the well's requirements.

Abstract: A two-part structural element for a downhole tool is disclosed, and methods of making the same. The two parts are a moldable plastic second part and a first part being an insert for placement in a mold, typically before a thermoset or thermoplastic second part is poured or otherwise placed in the mold. One or both of the two parts may be degradable in a downhole fluid.
