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.

Claim (Index 1):
A downhole tool for temporarily isolating zones in a well, comprising;\n a first subassembly and a second subassembly engaged with each other, a lower end of the second subassembly being located within the first subassembly, the engaged first subassembly and second subassembly having inner walls that define a bore through the tool; a sealing member located within the bore of the engaged first subassembly and the second subassembly, the sealing member comprising a disc and a base:\n the disc having an outer face and an inner face, the outer face and the inner face each having a concave configuration relative to the sealing member's base and being separated from each other by one or more distances, the sealing member comprised to resist greater downward pressure against the outer face of the disc before the downward pressure breaks the disc than the sealing member resists upward pressure against the inner face of the disc before the upward pressure breaks the disc, the outer face having a lower circular edge where the outer face's convex configuration ends, the circular edge being the disc's lower end, and having a diameter between opposing sides of the outer face's circular edge, and the disc being frangible; and \n the base depending downward from the disc, the base being a cylinder having a cylindrical outer surface and a cylindrical inner surface, an upper end proximal the disc and a lower end distal from the disc, the diameter of the outer surface of the base being the same as the diameter between opposing sides of the outer face's circular edge, so the outer surface of the base is a perpendicular projection of the outer face's circular edge from the outer surface's upper end to the outer surface's lower end, the inner surface forming a bore through the base; \n wherein the upper and lower ends of the outer surface of the base have equal diameters, the lower end of the base not having an expanded footing; \n wherein the distance between the inner surface and the outer surface of the base is less than the height of the inner face of the disc from the apex of the disc's inner face to the lower end of the disc; [base thinner than cone height] \n wherein the disc and the base are composed of the same material, namely ceramic, engineered plastic, carbon fiber, epoxy, fiberglass, or any combination thereof and are an integral unit; \n the first subassembly has an inner shoulder and the lower end of the base is supported by the first subassembly's inner shoulder; a first seal located about the base, distal from the disc, the first seal being a circular seal sized and configured to be compressed against the base to form a fluid-tight barrier with the base when the sealing member is mounted in the downhole tool; a second seal located around the sealing member, the second seal being a circular seal sized and configured to be positioned between the sealing member and the second assembly and compressed to form a fluid tight barrier with the second subassembly when the sealing member is mounted in the downhole tool; a third seal located between the first subassembly and the second subassembly and compressed between the first subassembly and the second subassembly to form a fluid tight barrier between the first subassembly and the second subassembly; the sealing member sized and configured to form a fluid-tight barrier in the bore of the tool, and the sealing member configured and comprised so breaking the frangible disc opens the bore of the tool to fluid flow.
