Abstract: In one embodiment, a telemetry controller may be configured to operate in any suitable combination of modes including pulse overdrive, multi-baud rate encoding, and/or high-resolution M-Ary encoding. Further, in some embodiments, an artificial intelligence engine may generate one or more machine learning models trained to operate in any of the combination of modes based on one or more parameters (e.g., condition of a downhole device, condition of a telemetry channel, condition of a well in which the downhole device is disposed, weather condition, condition of another system, or some combination thereof).

Abstract: The present invention is directed to an apparatus for use on a structural member having a longitudinal axis, the structural member being configured to propagate stress wave energy in an operational state, the stress wave energy being characterized by an operational frequency spectrum. The apparatus has a housing assembly including a first end, a second end, and one or more protective enclosures configured to accommodate one or more devices. The housing assembly is configured to be rotationally registered to the structural member when coupled to the structural member, and is characterized by a predetermined housing mass. A spring arrangement is coupled between the structural member and the first end and/or coupled between the structural member and the second end in the operational state. The spring arrangement is characterized by a predetermined force-displacement relationship. The housing assembly and the spring arrangement form an isolation filter characterized by a predetermined spectral transfer function, the predetermined spectral transfer function being a function of the predetermined housing mass and the predetermined force-displacement relationship. The predetermined spectral transfer function includes a passband having frequencies that are substantially outside the operational frequency spectrum wherein the stress wave energy is substantially attenuated in the operational state so that the housing member is substantially isolated from the stress wave energy.

Abstract: A coupling mechanism is disclosed for coupling a wireless communication device to a locating profile in a wellbore. The coupling mechanism comprises a coupling body arranged for connection to the wireless communication device, and an anchoring unit. The coupling body includes a conical portion with a tapered outer surface. The anchoring unit has a tapered inner surface arranged to oppose the tapered outer surface of the coupling body. The coupling body and the anchoring unit are configured for relative movement to cause the anchoring unit to expand radially to grip the locating profile.

Abstract: Disclosed herein are methods for performing downhole operations. The methods include determining, at the earth surface, a first depth value of a downhole component in a borehole, transmitting to the downhole component in the borehole a first signal indicating the first depth value, changing a depth of the downhole component in the borehole, determining, at the earth surface, a second depth value of the downhole component in the borehole, transmitting, to the downhole component in the borehole, a second signal indicating the second depth value, and updating a downhole operation performed by the downhole component based on at least one of the first depth value and the second depth value.

Abstract: The detection of a barrier behind a wellbore casing involves the injection of a fluid into the wellbore casing or the pumping of a fluid from the wellbore casing, and the monitoring in real-time of the fluid properties in two downhole fluid volumes separated by a packer. A detection system utilizes a pipe string equipped with a telemetry that is capable of transmitting fluid property data to a surface monitor while the pipe string remains in the wellbore casing, and preferably while the packer remains set against the wellbore casing.

Abstract: A downhole multi-modality inspection system includes a first imaging device operable to generate first imaging data and a second imaging device operable to generate second imaging data. The first imaging device includes a first source operable to emit energy of a first modality, and a first detector operable to detect returning energy induced by the emitted energy of the first modality. The second imaging device includes a second source operable to emit energy of a second modality, and a second detector operable to detect returning energy induced by the emitted energy of the second modality. The system further includes a processor configured to receive the first imaging data and the second imaging data, and integrate the first imaging data with the second imaging data into an enhanced data stream. The processor correlates the first imaging data and the second imaging data to provide enhanced data for detecting potential wellbore anomalies.

Abstract: Interrogation tools and methods are used to efficiently locate cable behind casing. The interrogation tool has at least one electromagnetic transmitter and receiver. An electromagnetic field is emitted from inside the tubular, whereby it interacts with the tubular and cable to produce a secondary electromagnetic field. The secondary electromagnetic field is measured by the receiver(s) from at least two different positions inside the tubular to produce corresponding response signals. The interrogation tool then compares the response signals to baseline response signals, whereby the position of the cable is determined. The electromagnetic measurements can be acquired simultaneously or sequentially.

Abstract: Methods, systems, and techniques for controlling voltage applied across a piezoelectric stack of a downhole acoustic transmitter. At least one of the temperature of the stack and the compressive stress applied to the stack is monitored. At least one of the temperature of the stack and the compressive stress applied to the stack is compared to a temperature threshold and a stress threshold, respectively. When the stack signal is an alternating voltage signal and when at least one of the temperature of the stack and the compressive stress applied to the stack respectively exceeds the temperature threshold and the stress threshold, the stack signal is modified such that a negative polarity portion of the stack signal has a maximum magnitude less than a magnitude of a negative polarity limit.

Abstract: A system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a tubular body either above or below ground, such as in a wellbore. The nodes allow for wireless communication between one or more sensors residing at the level of a subsurface formation or along a pipeline, and a receiver at the surface. The communications nodes employ electro-acoustic transducers that provide for node-to-node communication along the tubular body at high data transmission rates. A method of transmitting data in a wellbore is also provided herein. The method uses a plurality of data transmission nodes situated along a tubular body and a specially configured network to accomplish a wireless transmission of data along the wellbore using acoustic energy.
