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.

摘要： A cutting table includes a lattice structure and a catalyst material deposited within voids formed within the lattice. The catalyst material is deposited in the voids during a sintering process that forms the lattice. The catalyst material has a coefficient of thermal expansion that is less than that of cobalt. The catalyst material is any one of chromium, tantalum, ruthenium, an alloy of cobalt, an alloy of a Group VIII metal and at least one non-catalyst metal, an alloy of two or more Group VIII metals, or a eutectic alloy. In certain embodiments, the catalyst material has a thermal conductivity that is greater than that of cobalt. In certain embodiments, the cutting table is bonded to a substrate, which is formed from a substrate material and a binder material. In some embodiments, the binder material and the catalyst material are the same; while in others, they are different.

摘要： A thermally stable polycrystalline diamond cutter and method for fabricating the same. The cutter includes a substrate and a cutting table bonded thereto. The cutting table includes a cutting surface, a first beveled edge, a second beveled edge, a side surface, and an opposing surface that is adjacent to the substrate. The first beveled edge extends outwardly at a first angle from the cutting surface towards the substrate. The second beveled edge extends outwardly at a second angle from the first beveled edge towards the substrate. The side surface extends from the second beveled edge to the opposing surface. The cutting table is formed from a polycrystalline diamond structure having interstitial spaces disposed therebetween and a catalyst material disposed within the spaces in an untreated layer and not within a treated layer. The untreated layer includes the entire side surface.

摘要： A method for non-destructively characterizing one or more regions within a polycrystalline structure using capacitance and eddy current measurements. The eddy current measurements include at least one of an impedance amplitude and a phase shift angle. The capacitance is measured one or more times and compared to a first calibration curve to determine an estimated leaching depth within the polycrystalline structure. A first data scattering range is ascertained from the capacitance measurements to determine a relative porosity or the leaching quality within the polycrystalline structure. The eddy current is measured one or more times and compared to a second calibration curve to determine an estimated leaching depth within the polycrystalline structure. A second data scattering range is ascertained from the eddy current measurements to determine a relative porosity or the leaching quality within the polycrystalline structure. Results from both measurements are used to ascertain a quality of the polycrystalline structure.
