    摘要： A repaired polycrystalline diamond cutter and method for fabricating the same. The cutter includes a damaged substrate that includes at least one void therein, a polycrystalline diamond table coupled to the damaged substrate, and a paste compound disposed within the voids formed about the damaged substrate. The damaged substrate and the paste compound collectively form a full circumference. The method includes obtaining a damaged cutter that includes a polycrystalline diamond table coupled to a damaged substrate having at least one void formed therein, applying a paste compound within the at least one void, melting the paste compound via induction heating, bonding the paste compound to the substrate and forming a processed PDC cutter, and grinding at least a portion of the paste compound from the processed PDC cutter to form the repaired cutter.

    摘要： A target cylinder and a method for testing a superhard component thereon. The target cylinder includes a first end, a second end, and a sidewall extending from the first end to the second end. At least one of the second end and the sidewall is an exposed portion that makes contact with the superhard component to determine at least one property of the superhard component. The exposed portion comprises at least one synthetic material having at least one of a compressive strength raging from about 12 kpsi to about 30 kpsi, an abrasiveness ranging from about 1 Cerchars to about 6 Cerchars, and an iron content ranging from about 5 percent to about 10 percent. Optionally, the exposed portion further comprises a second material interveningly positioned between or within the synthetic material in a predetermined and repeatable pattern.

    摘要： A target cylinder, a method for testing a superhard component thereon, and a method for selecting an untested component for use in field applications. The target cylinder includes a first end, a second end, and a side wall extending from the first end to the second end. At least one of the second end and the sidewall is an exposed portion that makes contact with the superhard component to determine at least one property of the superhard component. The target cylinder is formed from a first material evenly distributed throughout a second material. Upon testing superhard components at one or more impact frequencies, untested superhard components are selected based upon field anticipated impact frequencies.

    摘要： A catalyst removal apparatus and method for removing catalyst from a polycrystalline cutter. The cutter includes a substrate and a cutting table. The apparatus includes a tank forming a cavity therein, an electrolyte fluid occupying the cavity, the cutter, a covering surrounding at least a portion of the cutter's sidewall and extending from at least the substrate's top surface towards the bottom surface, a cathode submersed within the fluid, and a power source. The cutting table is submersed within the fluid and positioned near the cathode, thereby forming a gap therebetween. The power source is coupled to the cutter and the cathode and electrolyzes the fluid to react with the catalyst in the cutting table to produce a salt. The salt dissolves in the fluid and is removed from the cutter. Optionally, a transducer is sonically coupled to the cutter and emits vibrations to remove salt from the cutting table.

    摘要： A method, system and apparatus for testing properties of a rock formation surrounding a wellbore in situ. The apparatus includes a tool body, one or more indenters, and one or more acoustic sensors. The body includes an outer surface that defines one or more cavities therein. Each cavity extends into the body. Each indenter is positioned within a corresponding cavity and is positionable into an operating position and a non-operating position. The acoustic sensor is positioned within the cavity and adjacent to the indenter. The indenter is positioned at least partially beyond the outer surface when in the operating position. The acoustic sensor senses one or more acoustic events occurring when the indenter is in the operating position. The apparatus is inserted into the wellbore. Once inserted, the indenter applies a load onto the rock formation causing cracking and the sensor receives the generated acoustic transmissions. The transmissions are analyzed.
