  • Patent number: 11391105
    Abstract: A method and system for downhole pulse generation determines an optimal frequency and, in some embodiments, amplitude of axial pressure pulses to maximize the rate of penetration. Specifically, one or more sensors may be disposed on or near an axial oscillation tool that provides near real-time raw sensor data relating to speed, velocity, and acceleration of the tool. With this sensor data, an optimal set of parameters, namely an optimal frequency and, in some embodiments, amplitude may be determined based on the hydraulic conditions and frictional forces of the actual drilling environment. An optimizing control system may directly communicate these parameters to the axial oscillation tool or pass the parameters to an axial oscillation tool control system that controls the operation of the tool. Advantageously, frictional forces may be substantially reduced, the rate of penetration may be substantially enhanced, and power consumption may be intelligently managed.
