This disclosure presents a process for communications in a borehole containing a fluid or drilling mud, where a conventional mud pulser can be utilized to transmit data to a transducer. The transducer, or a communicatively coupled computing system, can perform pre-processing steps to correct the received data using an average of a moving time window of the received data, and then normalize the corrected data. The corrected data can then be utilized as inputs into a machine learning mud pulse recognition network where the data can be classified and an ideal or clean pulse waveform can be overlaid the corrected data. The overlay and the corrected data can be fed into a conventional decoder or decoded by the disclosed process. The decoded data can then be communicated to another system and used as inputs, such as to a well site controller to enable adjustments to well site operation parameters.

Systems, methods, and computer-readable media for in-situ calibration of magnetic field measurements. In some examples, a method can involve generating a magnetic field via a magnetic field source that is coupled to a downhole tool. The magnetic field source can be located within a fixed distance from one or more sensors coupled to the downhole tool. The method can also involve obtaining respective field measurements of the known magnetic field from the one or more sensors, and comparing the respective field measurements from the one or more sensors with respective reference measurements previously obtained from the one or more sensors to yield respective comparisons. The method can then involve determining, based on the respective comparisons, a respective sensitivity drift for each of the one or more sensors.

In some embodiments, an apparatus and a system, as well as methods, include sampling a received signal that represents a downhole signal source, at a sampling frequency and for a sampling duration, to provide a sampled signal. Further activity may comprise detecting a frequency of a component of the sampled signal from inspection of a frequency domain representation of the sampled signal. Further activity may comprise adjusting at least one operating frequency for the downhole tool such that the at least one operating frequency is outside a frequency range from the frequency of the component of the sampled signal. Additional methods, apparatus, and systems are disclosed.

Systems for synchronizing downhole subs are disclosed. Some system embodiments may include a first downhole sub including a clock signal generator configured to generate an unmodified clock signal. The first downhole sub may also include a modification circuit configured to modify the clock signal. The system may also include a second downhole sub comprising a phase-locked loop circuit configured to receive as input the modified clock signal and output a second clock signal synchronous with the unmodified clock signal.
