  • Patent number: 10618814
    Abstract: Diamond bodies and methods of manufacture are disclosed. Diamond bodies are formed from at least a bimodal, alternatively a tri-modal or higher modal, feedstock having at least one fraction of modified diamond particles with a fine particle size (0.5-3.0 ?m) and at least one fraction of diamond particles with coarse particle size (15.0 to 30 ?m). During high pressure—high temperature processing, fine particle sized, modified diamond particles in the first fraction preferentially fracture to smaller sizes while preserving the morphology of coarse particle sized diamond particles in the second fraction. Diamond bodies incorporating the two fractions have a microstructure including second fraction diamond particles dispersed in a continuous matrix of first fraction modified diamond particles and exhibit improved wear characteristics, particularly for wear associated with drilling of geological formations.

  • Patent number: 10301908
    Abstract: An array of sliding sleeve valves are uniquely addressable without control lines or wires to open for a treatment and then close and then selectively open for production. The discrete movements employ an available pressure source such as tubing pressure and change the piston areas on opposed sides of a sliding sleeve valve to get the desired movements. Access valves to tubing pressure can be actuated in a desired sequence with signals such as acoustic or electromagnetic, for example. Access to one piston area that communicates opposed and offsetting piston areas to the tubing hydrostatic can be achieved with a straddle tool breaking a rupture disc. The piston is then in pressure balanced and can be moved in a desired direction with the straddle tool straddling access locations to the piston from above or below.

  • Patent number: 10287824
    Abstract: A polycrystalline diamond compact includes a polycrystalline diamond material having a plurality of grains of diamond bonded to one another by inter-granular bonds and an intermetallic gamma prime (??) or ?-carbide phase disposed within interstitial spaces between the inter-bonded diamond grains. The ordered intermetallic gamma prime (??) or ?-carbide phase includes a Group VIII metal, aluminum, and a stabilizer. An earth-boring tool includes a bit body and a polycrystalline diamond compact secured to the bit body. A method of forming polycrystalline diamond includes subjecting diamond particles in the presence of a metal material comprising a Group VIII metal and aluminum to a pressure of at least 4.5 GPa and a temperature of at least 1,000° C. to form inter-granular bonds between adjacent diamond particles, cooling the diamond particles and the metal material to a temperature below 500° C., and forming an intermetallic gamma prime (??) or ?-carbide phase adjacent the diamond particles.

  • Publication number: 20100244595
    Abstract: The motor of an electrical submersible pump generates a significant amount of heat that can be removed by transferring it to the well production fluid. Grooves in the stator and motor housing facilitate more rapid heat transfer from the rotor and stator, through the motor lubricant, to the motor housing. Increased heat transfer to the motor housing facilitates increased heat transfer to the production fluid on the outside of the motor housing.

    Abstract: The present invention provides a method and apparatus for determination of the quality of a formation fluid sample including monitoring permeability and mobililty versus time to determine a filtrate contamination level, single phase state without gas and solids in the formation fluid, as it existed in the formation and the determination of laminar flow from the formation. The present invention also enables determination of an optimal pumping rate to match the ability of a subsurface formation to produce a single phase formation fluid sample in minimum time. The method and apparatus also detect pumping problems such as sanding and loss of seal with borehole.

  • Publication number: 20040236512
    Abstract: The present invention provides a chemometric equation to estimate fluid density, viscosity, dielectric constant and resistivity for a formation fluid sample downhole. The chemometric estimates can be used directly as estimated values for fluid density, viscosity, dielectric constant and resistivity for a formation fluid sample downhole. The chemometric estimates can also be plugged into a Levenberg-Marquardt (LM) non-linear least squares fit, as an initial estimate of the parameter to be estimated by the LM fit. If the initial parameter estimate is too far from the actual parameter values, the LM algorithm may take a long time to converge or even fail to converge entirely. The present invention estimates an initial value of a parameter that provides a high probability that the LM algorithm will converge to a global minimum.
