    Abstract: Resonating sensors for use in high-pressure and high-temperature environments are provided. In one embodiment, an apparatus includes a sensor with a double-ended tuning fork piezoelectric resonator that includes a first tine and a second tine. These tines are spaced apart from one another so as to form a slot between the first and second tines. The width of the slot from the first tine to the second tine varies along the lengths of the first and second tines. Various other resonators, devices, systems, and methods are also disclosed.

  • Patent number: 12025238
    Abstract: A core rod has internal and external profiles disposed in a housing assembly. A power spring in cooperation with the core rod within the housing assembly is connected to a power spring stopper that is fixed to the housing assembly with at least one shear screw. An inner axial cycling piston bar includes an external profile for mating engagement with the internal profile of the core rod. The inner axial cycling piston bar is connected to a piston in cooperation with a cycling spring, and the piston is configured to move in an upward direction. When a downward force exerted by the cycling spring exceeds the upwardly applied cycling force, the piston, the inner axial cycling piston bar, and the external profile move in a downward direction, thereby causing the core rod to move an incremental distance in the downward direction, which compresses the power spring by the incremental distance.

  • Patent number: 12018559
    Abstract: The disclosure relates to a method for flagging at least an event of interest in an unlabeled time series of a parameter relative to a wellsite (including to the well, formation or a wellsite equipment), wherein the time series of the parameter is a signal of the parameter as a function of time. The disclosure also relates to a method for evaluation a downhole operation such as a pressure test using a pressure time series. Such methods comprises collecting a time series, extracting at least an unlabeled subsequence of predetermined duration in the time series, and assigning an event of interest a label, in particular representative of the status of the downhole operation, to at least one of the unlabeled subsequences. A command may be sent to a wellsite operating system based on assigned label.

  • Patent number: 12018980
    Abstract: A non-linear dynamic process such as multiphase flow is characterized to determine a condition of the process. A sensor may obtain information about strain, vibration, flow rate, etc. during the process. That sensor data may be plotted, and at least one perceptual hash can be generated from the plot. The perceptual hash can be compared against a database storing plots or hashes for non-linear dynamic responses for different sensor types or processes. A best fit hash may be identified and used to determine what conditions are occurring in the field, or multiple near fits can define an envelope of experimental/reference conditions with similar non-linear dynamics to the field system. Multiple hash comparisons may be used to refine the envelope, determine a best fit, or determine what measurement would help discriminate the flow conditions.

  • Patent number: 12018999
    Abstract: A test system for a pressure control equipment (PCE) stack includes a pump for directing fluid into the PCE stack, a drive for operating the pump to control fluid flow into the PCE stack, and a controller communicatively coupled to the drive and a sensor that transmits sensor data indicative of pressure within the PCE stack. The controller instructs the drive to cause the pump to direct fluid into the PCE stack until the sensor data indicates that the pressure within the PCE stack has reached a threshold pressure, blocks fluid flow into and out of the PCE stack upon receiving sensor data indicating the pressure within the PCE stack has reached the threshold pressure, monitors the pressure within the PCE stack over a time interval, and determines a condition of the PCE stack based on a change in the pressure within the PCE stack during the time interval.

  • Patent number: 12006820
    Abstract: Systems and methods presented herein include sidewall coring tool assemblies used to return core plugs of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. A coring bit and a coring shaft of the present disclosure allow space for cuttings to move away from the bit face when drilling into a formation. In addition, certain embodiments include a plurality of inlets disposed circumferentially on an external surface at a first axial end of the coring shaft, a plurality of internal grooves disposed on an internal surface of the coring shaft, and/or a plurality of fins disposed on the external surface to direct flow of drilling and debris away from the coring bit. In addition to providing more space for cuttings to move away from the coring bit, the torque needed to drive the bit is lessened as the surface area of the bit contacting or engaging the formation is reduced.

  • Patent number: 12000217
    Abstract: Systems, methods, tools, and kits are used to reducing shocks and vibrations in tools, including downhole drilling tools. In at least some embodiments, shock and vibration reduction can be enhanced within tools that include an annular chassis within a collar. Existing locations where a gap exists are identified, and clamps, alignment features, joints, or other components can be modified or included to reduce the gap between the chassis and the collar. This includes a tool in which the chassis includes a flow tube or other tool with an axis that is offset from the axis of the chassis. Minimizing the gap can include providing three-point contact, which stabilizes the internal component within the collar. In a downhole environment, a downhole tool that includes the collar and chassis can perform a drilling or other downhole operation, and the internal vibration within the collar is reduced.

  • Patent number: 12000973
    Abstract: Aspects described herein provide for methods and apparatus for characterizing azimuthal heterogeneities in a barrier installed outside an outer casing in a borehole traversing a formation in a cased hole configuration including an inner and outer casing. The approach is based on specific attributes in sonic signals acquired with an azimuthal and axial array receiver system located inside the inner casing. The methods include slowness-time-coherence (STC) processing based on specific arrivals identified in data acquired by axial arrays associated with multiple azimuthal sections of the receiver system. The specific arrivals contain STC signatures that can be examined in terms of coherence amplitude and localization within STC maps. Based on specific attributes in the sonic signals, an azimuthal coverage of the outer casing annular contents can be created.
