Serial hybrid downhole telemetry networks

A hybrid telemetry system includes a plurality of telemetry networks configured to communicate a modulated signal representing digital data along adjoining sections of a pipe string. The plurality of telemetry networks may each be optimized or particularly suitable for the configuration of the pipe string, the well, and/or the environment of the well occurring in each of the adjoining sections. Some of the plurality of telemetry networks may overlap to provide redundancy of the communication of the digital data.

Downhole dynamometer

SYSTEM AND METHOD FOR MEASURING DOWNHOLE MUD FLOW DENSITY
20230003628 · 2023-01-05 · ·

A system and method of determining a density of a drilling fluid in a wellbore. The system includes a drill string in the wellbore, the drill string including a downhole rotor. A drilling fluid flowing through the drill string in the wellbore causes the downhole rotor to rotate relative to the drill string. A brake is configured to apply a first brake torque to the downhole rotor to place the downhole rotor in a first state. A torque measurement system is configured to determine the applied first brake torque. A rotor speed measurement system is configured to measure a first downhole rotor speed of the downhole rotor having the drilling fluid flowing therethrough with the downhole rotor in the first state. A processor is configured to determine a density of the drilling fluid from the measured first downhole rotor speed, and the determined applied first brake torque.

Telemetry system combining two telemetry methods

A combined telemetry system that can be used while drilling a wellbore consists of a multi-hop telemetry method and a single-hop telemetry method combined in parallel. The multi-hop and single-hop methods can be operated in parallel, for example, so that each telemetry method caries data concurrently from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly. The multi-hop and single-hop methods can also be operated in series, for example, so that data from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly are first carried with the single-hop telemetry method and then transferred to the multi-hop telemetry method at one or more node(s) close to the surface. Preferably, the multi-hop telemetry method can also carry data from along-string sensors. Another combined telemetry system that can be used while drilling a wellbore consists of two single-hop telemetry methods combined in parallel.

Method to manipulate a well using an overbalanced pressure container

A method to manipulate a well, comprising running an apparatus (60a) having a container (68a) with a volume of gas at a higher pressure than a surrounding portion of the well. The well is isolated, and a wireless control signal, such as an electromagnetic or acoustic signal, is sent to operate a valve assembly (62a) to selectively allow or resist fluid exit from a portion of the container (68a), via a port (61a). Some of the pressurised gas may itself be expelled in to the surrounding portion of the well, or it may be used to drive a fluid out of the container, such as an acid.

PUMP HARMONIC NOISE ADVISOR

A method includes receiving a signal having a telemetry portion and a noise portion. The method may also include identifying one or more harmonic frequencies in the signal. The method may also include determining whether the one or more harmonic frequencies are in a predetermined frequency band. The method may also include determining whether a signal-to-noise ratio (SNR) of the signal is below a predetermined SNR threshold. The method may also include generating one or more notifications in response to the determination whether the one or more harmonic frequencies are in the predetermined frequency band and the determination whether the SNR is below the predetermined SNR threshold.
