摘要： A testing device that includes a wear testing device, a sensor array, and a controller. The wear testing device includes a sample rotation element configured to hold and to rotate a sample; and a cutting element holder configured to hold a cutting element and to engage the cutting element with the sample as the sample rotates. The sensor array includes an acoustic emissions (AE) sensor array comprising a plurality of AE sensors, the plurality of AE sensors configured to measure a plurality of acoustic signals generated during engagement between the cutting element and the sample; and a load sensor.

摘要： A wellbore fluid monitoring system includes a housing, a first sealing element, a second sealing element and a sealing unit. The housing is configured to be securely disposed in a portion of an annulus within a bell nipple below a rotary table of a wellbore drilling assembly. The annulus is formed by a drill string of the wellbore drilling assembly and an inner wall of a wellbore being drilled by the wellbore drilling assembly. The housing includes a first open end and a second open end. The housing is configured to house an air flow sensor disposed within the housing. The first sealing element is attached to the first open end of the housing. The first sealing element is configured to seal and unseal the first open end. The second sealing element is attached to the second open end of the housing. The second sealing element is configured to seal and unseal the second open end. The sealing unit is disposed in the portion of the annulus. The sealing unit is connected to the housing, the first sealing element and the second sealing element. The sealing unit is configured to actuate the first sealing element and the second sealing element to seal or unseal the first open end and the second open end, respectively, based on a liquid level in the portion of the annulus.

摘要： Systems and methods for managing a loss circulation zone in a subterranean well include a tool housing located on a surface of a tubular member with a tool cavity that is an interior open space within the tool housing. An electromechanical system is located within the tool cavity and has a printed circuit board, a microprocessor, a sensor system, a power source, and a communication port assembly. A release system can move a deployment door of a deployment opening of the tool housing between a closed position and an open position. The deployment opening can provide a flow path between the tool cavity and an outside of the tool housing. The release system is actuable autonomously by the electromechanical system. A releasable product is located within the tool cavity and can travel through the deployment opening when the deployment door is in the open position.

摘要： Methods and systems are described for drilling a wellbore. A method includes: sensing electrical resistance of an insulated conductor extending from a surface of a drill bit to a sensor inside the drill bit; calculating drill bit dimensions based on the sensed electrical resistance; and transmitting sensed electrical resistance, calculated drill bit dimensions, or both uphole to a system for controlling drilling operations.

摘要： An apparatus includes an outer structure body having an inner surface defining a cavity and an inner structure body rotatably supported within the cavity. The inner structure body has an outer surface in opposing relation to the inner surface and a central bore. Movable elements are positioned along the inner surface and movably coupled to the outer structure body. Ball elements are positioned along the outer surface and coupled to the inner structure body for movement with the inner structure body. The ball elements releasably contact the movable elements and impart motion to the movable elements in response to relative motion between the inner structure body and the outer structure body. Energy harvesters are positioned to generate electrical charges based on piezoelectric effect or magnetostrictive effect when motion is imparted to the movable elements by the ball elements.

摘要： A system includes sensing modules positioned along a length of a drill string. Each sensing module includes a structure arrangement composed of an outer structure body having a cavity and an inner structure body rotatably supported within the cavity. The structure arrangement is coupled to the drill string such that rotation of the drill string produces a relative rotation between the structure bodies. Ball elements are disposed in a gap between the structure bodies and move along a predetermined path defined in the gap in response to relative rotation between the structure bodies. Movable elements are positioned to physically interact with the ball elements as the ball elements move along the predetermined path. Energy harvesters in the sensor modules generate electrical energy from the mechanical energy produced by physical interaction between the ball elements and movable elements. The sensing modules include sensors to measure parameters in the drill string environment.
