  • Publication number: 20170370203
    Abstract: The aspects described herein assist in mitigating vibrations arising from torsional energy accumulating on a drill string in a wellbore during drilling operations. A first sensor obtains torque measurement data at or near the top drive of the drilling rig. A second sensor may obtain weight on bit information. The controller receives the measured data, combines it with a first gain to obtain a first output value and a second gain to obtain a second output value. The first output value is provided to the top drive to adjust a speed of operation of the top drive, and the second output value is provided to the axial drive providing motion along a vertical axis of the drilling rig to adjust a speed of the vertical motion. In combination, the adjustments to the top drive and axial drive movements mitigate stick-slip in an automated manner more effectively than either individually.

    Abstract: A method and an arrangement for operating a process for extracting a fluid in a borehole are optimized. In the case of deep wells, the location of an interface depth in the borehole is detected. A pressure measurement of the pressure at the head of the borehole is made. The pressure in the liquid in the borehole below the interface depth is determined from the measured pressure at the head of the borehole and the detected location of the interface depth. The determination of this pressure is used for regulating the performance of an extracting device for the liquid that is to be extracted.

  • Publication number: 20170370209
    Abstract: During fracking processes, fluid is injected into the injection wells to cause micro-fractures in the shale. Contact between shale and water causes the development of micro-fractures. Given the deep location of the injection wells, the water is under high pressure that can build up over time and could potentially cause tremors. Based upon experiments on Pierre shale, it has been determined that the appearance of micro-fractures in shale begin with the saturation of capillaries, followed by ionic and diffusive transport of water into the shale clays. Using this discovery, a method for predicting the post-fracking pressure build-up in shale is disclosed.

  • Publication number: 20170370241
    Abstract: Turbine and compressor casing abradable components for turbine engines include abradable surfaces with a zonal system of forward (zone A) and rear or aft sections (zone B) surface features. The zone A surface profile comprises an array pattern of non-directional depression dimples, or upwardly projecting dimples, or both, in the abradable surface. The dimpled forward zone A surface features reduce surface solidity in a controlled manner, to help increase abradability during blade tip rubbing incidents, yet they provide sufficient material to resist incoming hot working fluid erosion of the abradable surface. In addition, the dimples provide generic forward section aerodynamic profiling to the abradable surface, compatible with different blade airfoil-camber profiles. The aft zone B surface features comprise an array pattern of ridges and grooves.

  • Publication number: 20170370246
    Abstract: A method for forming a composite part of a gas turbine engine. The method includes assembling the composite part of a first composite material and a second composite material. The second composite material defines an outer surface of the composite part, and is selected to be curable at a cure temperature generated by heat from operation of the engine. The first composite material is selected to have an operating temperature limit less than the cure temperature. The method includes placing the composite part within the engine so that, in use, the second composite material is cured by exposure to the heat generated from operation of the engine. The second composite material thermally shields the first composite material from the heat generated from operation of the engine. The method includes operating the engine to cure the second composite material.

  • Publication number: 20170370247
    Abstract: The present disclosure provides a method for manufacturing a preform made of reinforcement fibers woven in a longitudinal direction. The preform is impregnated with resin in order to form an elongated element having a variable transverse cross-section. In one form, the method includes the step of simultaneously including a reduction (or increase) in width and an increase (or reduction) in height. The variable cross-section includes, along the length thereof, a consistent number (c) of continuous warp threads arranged in layers. The method for reducing width includes carrying out a change in weave, adding additional weft threads, and simultaneously drawing the teeth of the longitudinal beater reed closer together so as to increase the number of layers.
