  • Publication number: 20190024467
    Abstract: A system and method for orienting a tool in a near vertical wellbore. The system includes a tool string having a whipstock at an end thereof, at least two magnetometers oriented transverse to a longitudinal axis of the tool string, and a processor. A first set of magnetic measurements of the earths' magnetic field is obtained during rotation of the tool using a first of the at least two magnetometers and a second set of magnetic measurements of the earth's magnetic field is obtained during rotation using a second of the at least two magnetometers. The processor fits a curve to the first and second sets of magnetic measurements to determine a peak value, determines magnetic north from the determined peak value, determines a toolface orientation of the drill string with respect to the determined magnetic north, and anchors the whipstock at the selected depth and toolface orientation.

  • Patent number: 10187196
    Abstract: A method and a device for providing a global clock in a system, the terminals in the system are channel connected to each other via paths, each terminal is communicatively connected to a clock source ultimately via a signal recording unit, respectively, the clock source sends a calibration signal to the network, the signal recording unit records the current transmitting time T (0) of the calibration signal, each terminal will receive the calibration signal sequentially due to different distances from the clock source and will return the signal, the backward signals are returned to the signal recording unit along the network sequentially, and the signal recording unit records the time T (n) of each backward signal sequentially, in this way, the signal recording unit can then measure the delay between each terminal and the clock source signal, which can be used as a correction parameter to ensure that all terminals are in exactly the same time reference, in addition, in this way, there is no need to control the

  • Publication number: 20180238166
    Abstract: A method and apparatus for locating a collar of a casing of a wellbore is disclosed. A sensor for measuring a magnetic field is conveyed through the casing on a tool string. A physical model is formed of a process of obtaining a magnetic measurement of the casing with the sensor. A simulation of the physical model is run through a processor to select a design parameter of the tool that allows for using the sensor at a determined value of an operational parameter for obtaining the measurement at a selected signal-to-noise ratio. The tool is conveyed into the wellbore and the sensor set to the determined value of the operational parameter. The magnetic measurement of the casing is obtained using the sensor, and the collar is located using the obtained magnetic measurement.

  • Publication number: 20180128071
    Abstract: A bottom hole assembly (BHA) contains a motor and a section mill for milling in an uphole direction after blade extension with circulating fluid through the BHA. Below the section mill is sensing equipment to detect location of a bridge formed by the cuttings or swarf from the section mill. A secondary mill oriented for cutting in a downhole direction is located at the bottom of the BHA for use in removal of the bridge. The sensing equipment delivers in real time data as to the density of the bridge so that decisions to interrupt the section milling and to lower the secondary mill to the bridge can be made in real time. Cement is pumped and displaced by a wiper plug to plug and abandon the hole.
