Abstract: Improved apparatuses, systems, and methods for sealing a frac valve using pressurized fluid to drive one or more seal assemblies into sealing contact with a valve gate without substantial relative movement of the seal assembly components. In some embodiments, the improved apparatuses, systems, and methods provide a sealant to the face of the valve gate to ensure a fluid tight seal, a plurality of biased springs to ensure the seal assemblies are positioned properly to create a fluid tight seal, a shield to prevent fluids, particulates, and/or other materials from interfering with the operation of or damaging the seal assemblies, and/or a recess for receiving fluids, particulates, and/or other materials that would otherwise interfere with a fluid-tight seal or cause damage to the seal assemblies or valve gate.

Abstract: A drilling tool for use in drilling operations for providing shock absorption capability and lateral support to the rotary drill string. The telescoping axial load shock absorber is positioned immediately adjacent at least one lateral support provided by a reamer or stabilizer. The stabilizer preferably employs a removable fixed blade secured to the tool by an undercut groove. The roller cutter for a reamer is also mounted in a preferred unique manner with the mounting blocks secured in a recess having an undercut retainer portion in the event of bolting failure. The mounting's brackets may be formed integral of the tool body or attached by welding or the like. A preferred form of mounting a blade on a stabilizer tool is also disclosed.
