    Abstract: Described herein are systems, apparatuses, processes (also referred to as methods), and computer-readable media (collectively referred to as “systems and techniques”) for receiving data from or associated with apparatus (e.g., tools) deployed down a wellbore at speeds not previously possible. Information or data sent from a downhole tool for receipt by computers located at the surface of the Earth is often bandwidth limited for various reasons. Systems and techniques of the present disclosure allow for disposable fiber optic cables to be deployed into a wellbore that may be dedicated to sending data or sensed information uphole to a computer. This allows for additional amounts of data or sensed information to be sent to the computer when other communication mechanisms or pathways associated with a wellbore are bandwidth limited.

    Abstract: Disclosed are perturbation signaling systems and methods for use in a downhole well. Such systems can include a downhole tool configured to hang from a wellbore anchoring mechanism. The tool can have or associate with an energy harvesting system, a power management system, a sensing system, and a wireless communication system. A turbine generator can encode signals into flowing fluid through electric load and related changes in hydraulic energy, transmitting information through the fluid. A receiver station positioned at another well location can decode and or relay the signals. Signals can bypass impediments such as noise zones by inducing signals in adjacent parallel well environments such as an annulus. The receiver station can accumulate energy from repeated redundant signaling over time to enhance communication and signal resolution. An additional wireless communication system can receive and/or relay data to a remote location.

    Abstract: Methods and systems for training a machine learning model to process microseismic data recorded during fracturing of a subterranean geological formation are configured for selecting a volume in the subterranean geological formation, the volume comprising a set of vertices and a center, the set of vertices defining a first dimension; determining seismogram data for sources at the vertices of the volume and at the center of the volume; generating training data from the seismogram data, the training data relating values of seismogram data to values of moment tensor components; training a machine learning model using the training data; and determining, based on the trained machine learning model, a second dimension defined for the set of vertices, the second dimension being a maximum value enabling an accuracy for outputs of the trained machine learning model that satisfies a threshold.

    Abstract: The present disclosure relates to a method and system for monitoring a wellbore object using a reflected pressure signal. The method discloses providing at least one pump for performing hydraulic fracturing or a source of hydraulic pulse so that pressure signal propagates along the wellbore and reflects from the borehole objects; providing pressure sensor at wellhead; preprocessing of registered reflected pressure signal and pump noise; transforming the registered reflected pressure signal and pump noise from the frequency domain into time-frequency representation with Short Time Fourier Transform (STFT), computing a pump noise mask; applying the pump noise mask to the STFT representation to obtain a filtered reflected pressure signal; processing of the filtered reflected pressure signal for determining the reflection time from the downhole object, calculating the depth of the downhole object from reflected pressure signal by multiplying of the reflection time by the pressure signal propagation velocity. This method allows to perform wellbore monitoring without stop of current operations.

    Abstract: A servo valve in a servo pulser used to restrict flow to a larger main valve includes external stops on a housing to define rotational starting/stopping points and sweep zones for a servo rotor having digits for contacting the stops. The digits extend longitudinally away from the servo valve seat and extend into the sweep zones. Interaction between the stops and the digits in the sweep zones limit rotation of the rotor to a swept arc between the stops. The servo pulser rotor oscillates between stopping points in alternating clockwise/counterclockwise sweeps. Each sweep in a given direction creates one full pulse: closed, open, and closed. The servo pulser carries out a feedback/decision loop between hydraulic pulses (and sweeps) that receives information on one or more previous pulses and calculates how fast or slow it should drive the servo rotor for the current pulse.
