LUMINESCENT DIAMOND

Abstract

Luminescent diamond is made by subjecting a volume of diamond grains to high-pressure/ high-temperature conditions with or without a catalyst to cause the grains to undergo plastic deformation to produce nitrogen vacancy defects in the diamond grains, increasing the luminescent activity/intensity of the resulting diamond material. The consolidated diamond material may be further treated to further increase luminescent activity/intensity, which treatment may comprise reducing the consolidated diamond material to diamond particles, heat treatment in vacuum, and air heat treatment, which reducing process further increases luminescent activity/intensity. The resulting luminescent diamond particles display a level of luminescence intensity greater than that of conventional luminescent nanodiamond, and may be functionalized for use in biological applications.

Abstract

Cutting elements include a carbonate diamond-bonded body that is sintered under HPHT conditions in the presence of a carbonate material, where the body includes a matrix phase of intercrystalline bonded diamond with interstitial regions including the carbonate material, where the diamond-bonded body is sintered without a substrate. A matrix casting is formed and mechanically coupled to the body after the body is sintered, and a portion of the body surface is exposed along a surface of the matrix casting. The exposed body surface is thereafter intentionally treated to induce a compressive residual surface stress that is greater than a remaining portion of the body. The compressive residual surface stress is less than about 500 MPa, and from about 100 to 500 MPa, and a remaining region the body may have a residual stress of less than about 300 MPa, and less than about 100 MPa.

Abstract

Roller cutters comprise a diamond-bonded body joined to an infiltration substrate. An extension is joined to the substrate and includes first section having a diameter sized the same as the substrate, and an integral second section having a diameter smaller than the substrate. The extension is joined to the substrate during an HPHT process. The first section has a thickness greater than that of the infiltration substrate. The second section has an axial length greater than the combined thickness of the substrate and the first section. The extension has a strength and/or toughness greater than the substrate as a result of its material composition, e.g., the amount of binder phase material and/or the size of hard phase material. The roller cutter is rotatably disposed within a pocket internal cavity, wherein the pocket is attached to a drill bit.

The drill bit includes a bit body having a bit axis, and at least a first cone and a second cone coupled to the bit body. Each of the first and the second cones has a backface, a nose opposite the backface, and a cone axis of rotation. An array of cutting elements coupled to the first or second cones is in a band that lies between the backface and the nose. The cutting elements in the band are arranged at radial positions with respect to the bit axis and at least two adjacent cutting elements are at a same radial position within the array, and the remaining cutting elements are at different radial positions within the array.

Abstract

A method for maintaining pressure in a wellbore drilled from a drilling platform floating on a body of water includes the steps of pumping fluid at a determined flow rate into a drill string disposed in a wellbore and measuring fluid pressure within a fluid discharge line of fluid returning from the wellbore. The fluid discharge line has a variable length corresponding to an elevation of the floating platform above the bottom of the body of water. The wellbore pressure is determined at a selected depth in the wellbore or at a selected position along a drilling riser or variable length portion of the fluid discharge line using known parameters/methods. The determined wellbore pressure is adjusted for changes in length of the fluid discharge line corresponding to changes in the elevation of the floating platform relative to the bottom of the body of water. A backpressure system may be operated to maintain the adjusted determined wellbore pressure at a selected (or set point) value by applying backpressure to the wellbore.

Abstract

Polycrystalline diamond (PCD) constructions and cutting elements include a PCD body having a composite layer with a number of PCD particles dispersed in a surrounding PCD matrix. The composite layer has a wear surface including asperities projecting outwardly therefrom, where the asperities are formed from the PCD particles. In an embodiment, the asperities enhance the efficiency of breaking rock during a drilling operation. The body includes one or more PCD transition layers between the composite layer and a metallic substrate attached to the diamond-bonded body. The one or more transition layers may have a hardness that is the same or less than the hardness of the composite layer.
