  • Patent number: 9222316
    Abstract: A system and methodology facilitates extending the reach of coiled tubing during a well operation. The technique employs tubing which is deployed along wellbore. A plurality of extended reach devices is positioned along the tubing. Each extended reach device has at least one internal guide member oriented for extension into an interior of the tubing. The guide member engages and guides the coiled tubing during movement of the coiled tubing along the interior of the tubing, thus enabling an extended reach during a wellbore servicing application.

  • Patent number: 9000941
    Abstract: A method for estimating a steady state response of a drill string in a borehole includes calculating a first displacement of the drill string in a frequency domain for a first excitation force frequency and a number of multiples of this frequency using an equation of motion of the drill string. The equation of motion has a static force component, an excitation force component, and a non-linear force component with respect to at least one of a deflection and a derivative of the deflection of the drill string. The method further includes: transforming the first displacement from the frequency domain into a time domain; calculating a non-linear force in the time domain; calculating a frequency domain coefficient derived from the calculated non-linear force in the time domain; and calculating a second displacement of the drill string in the frequency domain using the equation of motion and the frequency domain coefficient.

  • Publication number: 20140196893
    Abstract: Many wellbore service operations involve placing a line in the wellbore. The line may be used to transmit power to downhole tools, convey signals from downhole-measurement instruments, or both. A problem associated with such operations involves drag forces experienced by the line as process fluids flow through the well, particularly the interior of a tubular body such as casing. The drag forces may cause the line to fail. Magnetizing the line solves this problem. During deployment, the line will migrate and become attached to the casing. Drag forces are significantly reduced because the line is no longer surrounded by moving fluid.

  • Patent number: 7506700
    Abstract: A method for steering a steerable mud motor while attached to a retrievable replaceable measurement while drilling device comprising: securing a directional drilling tool to a retrievable replaceable measurement while drilling device, orienting the retrievable replaceable measurement while drilling device with a spear axis of an orientation spear point of the directional drilling tool, and lowering the orientation spear point into a non-magnetic drill collar above a mud motor. An orienting mule shoe stinger is attached to a gyroscopic device, which is then inserted over the orientation spear point, which orients the gyroscoping device along the spear axis, enabling steering of the mud motor while attached to the retrievable replaceable measurement while drilling device, while maintaining full retrievability of the retrievable replaceable measurement while drilling device from the well.
