Patents by Inventor Colin J. Gillan

Colin J. Gillan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11859487
    Abstract: Systems, devices, and methods for measuring toolface angles on a drilling rig and calculating a slide stability score are provided. The slide stability score may represent an amount of consistency of the toolface angle of a bottom hole assembly (BHA) of the drilling rig during a slide drilling operation. Calculating the slide stability score may include measuring one or more toolface angles of the BHA during the slide drilling operation, comparing the measured one or more toolface angles, and calculating the consistency of the toolface angle using the measured one or more toolface angles.
    Type: Grant

  • Patent number: 11174718
    Abstract: Systems, devices, and methods for generating steering instructions to directing the operation of a drilling system are provided. The systems, devices, and methods may include determining an optimized path to navigate a Bottom Hole Assembly (BHA) to a steering target using one or more steering methods, such as straight line projections, rotary drilling projections, True Vertical Depth, Inclination, and Azimuth (TIA) calculations, and three dimensional ā€œJā€ (3DJ) calculations, and driving the BHA to the steering target using the optimized path.

  • Patent number: 9784035
    Abstract: Apparatuses, methods, and systems are described which assist in controlling toolface orientation of a bottom hole assembly. A controller instructs a top drive to oscillate a drill string an oscillation revolution amount to reduce friction of the drill string in a wellbore during a slide drilling procedure. A torque sensor detects torque at an interface between the drill string and the top drive, and the controller determines properties of a torsional wave from the detected torque that is propagating along the drill string during the slide drilling procedure. The controller determines a modification to the oscillation revolution amount and/or rotations per minute in order to control the toolface orientation in a desired manner. The top drive implements the determined modification and thereby assists in controlling the toolface orientation during the slide drilling procedure.
