Abstract: Tools and methods are described to measure dimensions of wellbores. Downhole caliper tools include: a downhole collar; an uphole collar; and a caliper sensor assembly disposed between the downhole collar and the uphole collar. The caliper sensor assembly include: an annular sensor module defining a plurality of radially extending tracks; and a caliper including: a plurality of linear slide arms, each linear slide arm at least partially disposed in the annular sensor module in one of the plurality of radially extending tracks and radially moveable relative to the annular sensor module, each linear slide arm extending from a first end within the annular sensor module to a second end outside the annular sensor module, and a cover extending from the downhole collar to the uphole collar. The annular sensor module can measure the radial position of the plurality of linear slide arms relative to the annular sensor module.

Abstract: Tools and methods are described to measure dimensions of wellbores. Downhole caliper tools include a downhole collar and an uphole collar having a running position and a sensing position. The uphole collar is farther from the downhole collar in the running position than in the sensing position. A caliper sensor assembly includes: a sensor module defining tracks extending parallel to an axis of the caliper tool, the sensor module positioned towards an uphole end of the caliper tool relative to the uphole collar; and a caliper disposed between the downhole collar and the uphole collar including: a flexible mesh extending from the downhole collar to the uphole collar. Movement of the uphole collar from the running position to the sensing position axially compresses and radially expands the flexible mesh. The annular sensor module can measure dimensions of the flexible mesh relative to the axis of the caliper tool.

Abstract: 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.

Abstract: Systems and methods for actuation of downhole devices are disclosed. The system includes a first cylindrical pipe having one or more first materials attached to an outer surface of the first cylindrical pipe, a second cylindrical pipe co-axial with the first cylindrical pipe and having a diameter greater than the first cylindrical pipe, the second cylindrical pipe comprising one or more second materials disposed on an inner surface of the second cylindrical pipe, wherein the first materials generate one or more signals when the first materials come in contact with the second materials, and a digital logic circuit configured to receive the one or more signals as input, and generate an output based on the input, the output configured for actuation of the downhole devices.

Abstract: Methods and systems for monitoring conditions within a wellbore of a subterranean well include extending a drill string into the subterranean well from a terranean surface. The drill string has an actuator assembly, a sensor compartment, and a plurality of sensors located within the sensor compartment. The actuator assembly is instructed to transmit a swarm release signal to a central power unit of the sensor compartment so that the central power unit of the sensor compartment releases certain of the plurality of sensors from the sensor compartment. Data from the sensors is transferred to a data processing system after the sensors reach the terranean surface.

Abstract: A casing for a drilling operation has a body portion having a length, a first end and a second end, an outer diameter, an inner diameter, and a central axis that is common to the outer diameter and the inner diameter, and an external thread formed on the outer diameter of the body portion, wherein the external thread starts at a first predetermined distance from the first end and ends at a second predetermined distance from the second end. The external thread includes a spiral groove or a helical thread formed on the outer diameter of the body portion. The casing includes a coating at least partially encapsulating the external thread, wherein the coating includes at least one material selected from the group consisting of polycrystalline diamond particles, diamond like carbon (DLC), tungsten carbide, boron nitride, silicon carbide, silicon nitride, and combinations thereof.

Abstract: Wireless mobile devices are injected into a wellbore with a cement slurry, during the cementing of casing, to monitor and evaluate cement sheath parameters. Passive, wireless sensors are utilized to not only measure the elastic constitutive properties of the cement sheath such as compressive strength, but also parameters of the cement sheath environment, such as temperature, pressure, humidity, pH and gases present, to identify potential issues about the structural integrity of the cement sheath, and provide timely warnings to perform remedial actions.
