A mud motor for use in a wellbore includes: a stator; a rotor, the stator and rotor operable to rotate the rotor in response to fluid pumped between the rotor and the stator; and a lock. The lock is operable to: rotationally couple the rotor to the stator in a locked position, receive an instruction signal from the surface, release the rotor in an unlocked position, and actuate from the locked position to the unlocked position in response to receiving the instruction signal.

A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the control device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool.

The present embodiments disclose a downhole communication technology involving slotted collar allowing electromagnetic waves to reach inserted probe receiver assembly. One embodiment shows transmitter/receiver as part of At Bit tool.

Systems and methods for wireless downhole telemetry are provided. The system includes a tubular located in a wellbore; a pressure controller located at or near a surface of the wellbore to send a digital command via a change in a pressure applied to the tubular; and a receiver disposed in the wellbore, wherein the receiver includes a mechanical pressure switch to detect the change in the pressure applied to the tubular.

This invention relates generally to analyzing fluid flow and calculating significant deviations in fluid flow. There is a system and a method. The system includes a user device, a video acquisition processor, a server, and a database. Generally, the method includes recording underwater fluid flow, analyzing the fluid flow using fluid flow and object detection algorithms, checking for deviations in recent fluid flow, and alerting a user.

A method can include receiving a target density value for a drilling fluid exiting a sedimentation device; receiving a measured density value for the drilling fluid directed to the sedimentation device, a measured density value for the drilling fluid exiting the sedimentation device, and an incoming flow rate value for the drilling fluid directed to the sedimentation device; and generating control instructions for control of an injection pump to regulate a diluent injection pump rate to dilute the drilling fluid entering the sedimentation device to achieve the target density value.

A method includes receiving first training well logs, generating second training well logs by injecting one or more different types of systematic errors, random errors, or both into at least a portion of the first training well logs, training a machine learning model to correct well logs by configuring the machine learning model to reduce a dissimilarity between at least a portion of the first and second training well logs, receiving one or more implementation well logs, and generating one or more corrected well logs by correcting at least a portion of the one or more implementation well logs using the machine learning model that was trained.

A cutting element (1) for a cutting tool has a sensor element, a body of super hard material (12) having a working surface, the sensor element being attached to a portion of the super hard material (12), and one or more conducting wires extending from the sensor element through one or more channels extending through the body of super hard material. The sensor element is bonded to the body of superhard material through a layer of ceramic adhesive.

A telemetry tool assembly for exploiting subsurface fluids and minerals through well construction and production. The assembly comprises a tube comprising a bore and a bore wall and first end and a second end. The respective ends each comprise internal and external upset portions welded to a pin end tool joint or box end tool joint, respectively. The upset portions comprise an internal and external conical transition section intermediate the respective tool joints and the tube. The internal conical transition section comprises at least one socket comprising a removeable cover and side and bottom surfaces within the internal conical transition section. The socket and cover comprise a seal between the cover and socket side walls. A sensor module comprising electrical equipment is disposed within the one or more sockets and the assembly comprises a wired drill pipe (WDP). The socket surfaces comprise a hardness greater than the internal transition section.
