Abstract: An apparatus includes a ballast that is configured to couple to an untethered downhole tool. The ballast includes a composite material. The composite material includes a first portion and a second portion. The first portion includes metallic particles. The first portion is configured to, while the ballast is coupled to the untethered downhole tool, provide weight to the untethered downhole tool to lower the untethered downhole tool into a well formed in a subterranean formation. The second portion includes a polymer matrix. The metallic particles of the first portion are distributed throughout the polymer matrix of the second portion. The second portion is configured to dissolve in response to being exposed to downhole fluid within the well at specified downhole conditions, thereby releasing the metallic particles of the first portions from the polymer matrix that has dissolved.

Abstract: A computer-implemented method for automated wellhead monitoring using imaging and computer vision is described. The method includes establishing a baseline for a wellhead using image dimension and perspective calibration. The method also includes constructing at least one computer vision model using images or video from a wellhead database and inputting unseen wellhead images to the trained at least one computer vision model. Additionally, the method includes extracting a wellhead shape and geometric information of the wellhead in the unseen wellhead images and estimating wellhead displacement and growth based on the extracted images.

Abstract: A downhole tool includes a body configured to move in a wellbore formed from a terranean surface to a subterranean formation in a direction downhole of the terranean surface independent of a downhole conveyance attached to the body; one or more sensors positioned in the body, the one or more sensors configured to measure a value associated with at least one of the wellbore or the terranean surface; and at least one mass positioned in the body and configured to adjust an orientation of the body in response to one or more forces acting on the body as the downhole tool moves in the wellbore in the direction downhole of the terranean surface.

Abstract: An untethered apparatus for measuring properties along a subterranean well includes a housing, and one or more sensors configured to measure data along the subterranean well. The data includes one or more physical, chemical, geological or structural properties in the subterranean well. The untethered apparatus further includes a processor configured to control the one or more sensors measuring the data and to store the measured data, and a transmitter configured to transmit the measured data to a receiver arranged external to the subterranean well. Further, the untethered apparatus includes a controller configured to control the buoyancy or the drag of the untethered apparatus to control a position of the untethered apparatus in the subterranean well. The processor includes instructions defining measurement parameters for the one or more sensors of the untethered apparatus within the subterranean well.

Abstract: Systems and methods for measuring phase flow rates of a multiphase production fluid are provided where a fluidic isolation chamber expands volumetrically in response to fluid pressure from a diverted multiphase production fluid. A pressure-regulating actuator regulates fluid pressure upstream of the fluidic isolation chamber and an upstream fluidic pressure sensor generates an upstream fluidic pressure signal. A fluidic control and analysis unit is configured to communicate with the upstream pressure sensor and the isolation chamber actuator to maintain fluidic pressure upstream of the fluidic isolation chamber as the multiphase production fluid is diverted to the fluidic isolation chamber. The unit generates a total flow rate QTOT as a function of chamber filling time and volumetric expansion and communicates with the fluidic phase detector to generate a relative occupancy indicator I for a target phase of the multiphase production fluid in the fluidic isolation chamber. A flow rate QP for the target phase is generated as a function of the total flow rate QTOT and the relative occupancy indicator I.

Abstract: An apparatus for determining properties of an uncharacterized downhole fluid. The apparatus comprises an oscillation driver circuit comprising an amplifier having an output and an input, a feedback loop between the output and input of an amplifier or a logic gate, an electromechanical resonator disposed within the feedback loop such that a the resonator is driven by the oscillation driver circuit, wherein a resonant frequency of the resonator defines an oscillation frequency of the oscillator circuit, and a switch device for causing the oscillator circuit to stop driving the resonator, which thereby enables observation of a decay rate of the oscillation of the electromechanical resonator within the uncharacterized fluid. The electromechanical resonator is enclosed in a conductive layer to protect the resonator against capacitive effects of the downhole fluid.

Abstract: Techniques for determining rheological properties of a fluid include actuating a resonator disposed in a volume that contains a fluid sample to operate the resonator in the fluid sample at a predetermined actuation scheme; measuring at least one characteristic of the resonator based on the operation of the resonator in the fluid sample; comparing the at least one measured characteristic to a rheological model that associates characteristics of the fluid sample to one or more rheological properties; and based on the comparison, determining one or more rheological properties of the fluid sample.
