Abstract: A combinatorial frequency system and method for transmitting data from LWD downhole operations to a surface location is provided. The system and method include obtaining data from at least one downhole sensor, encoding data by combinations of different harmonics, and (optionally) modulating the data using various frequency modulation techniques to produce a series of 3-40 bit rates. The system and method include transmitting the series as pressure wave signals through drilling fluid or through earth media by electromagnetic waves, detecting the signals, identifying at a surface location each frequency, modulating characteristics of each frequency, decoding each signal and forming output signals.

Abstract: A method for downlinking communication from a surface location to a bottom hole assembly during drilling operation is provided. The method includes pumping drilling fluid through a fluid line and through a drill string to the bottom hole assembly, and generating pressure wave signals by a modulator disposed against an outside surface of the fluid line at an outside-surface location of the fluid line. The modulator is disposed entirely outside of the fluid line. The method includes detecting and receiving at the bottom hole assembly the pressure wave signals generated by the modulator, and processing and decoding the pressure wave signals with a decoder associated with the bottom hole assembly to identify downlinking command purpose and required action for controlling drilling operations.

Abstract: Exemplary embodiments are directed to a system and method for continuous downlinking communication from a surface location to a bottom hole assembly during drilling operations. The system transmits harmonic pressure wave fluctuations generated by a modulator, which is disposed outside of a surface-located fluid line with a flap rotatably disposed entirely inside of the fluid line encoding data by harmonics. One letter of the combinatorial frequencies signal alphabet can have more than 200 different orthogonal frequencies components; each component represents a unique combination of downlinking command purpose and value. For deepest portion of a long trajectory well, the system uses a narrow frequency range (2-3 Hz) with two letters resulting in more than 250 combinations. The system provides continuous automatic downhole control of the signal-to-noise ratio to achieve robust decoding of downlinking signals with a transmission data rate ten times faster as compared to 1-2 bits per minute in the industry.
