  • Analysis of drillstring dynamics using angular and linear motion data from multiple accelerometer pairs
    Patent number: 9567844
    Abstract: Downhole drilling vibration analysis uses angular and linear motion data on a drilling assembly. During drilling operations, pairs of accelerometers measure the angular and linear motion of the drilling assembly. Processing circuitry is operatively coupled to the accelerometer pairs and is configured to determine type and severity of vibrations occurring during drilling based on the angular and linear motion data. Drilling operations can then be modified to overcome or mitigate the detrimental vibrations.

  • Directional Drilling Using Variable Bit Speed, Thrust, and Active Deflection
    Publication number: 20150090497
    Abstract: A downhole assembly for directionally drilling a borehole has a motor, a transmission, and a steering mechanism. The motor has a rotor driven in a stator by flow of drilling fluid therebetween. The transmission operatively couples the rotor to a drill bit for drilling the borehole. A flow control controls the flow of drilling fluid through an internal passage of the rotor. The flow control can thereby vary the drive of the rotor in a bit speed effect that preferentially cuts the wall of the borehole to achieve directional drilling. The flow control can also thereby create a differential pressure displacing the rotor along a longitudinal axis of the motor in a thrust effect. The steering mechanism responds to the displacement of the rotor and deviates a direction of the drill bit from the longitudinal axis of the motor to further achieve directional drilling. The bit speed effect, the rotor displacement, and the deviation are preferentially coordinated to coincide or at least operate together.
