Abstract: A system having an instrumented cutter of a drill bit including an on-cutter sensor for monitoring drilling performance metrics while performing drilling operations based on offset well data and a computing device is disclosed. The computing device executes a model development system configured to use the drilling performance metrics, surface drilling parameters, and characteristics of the instrumented cutter to train a machine learning (ML) model. The trained ML model is used to optimize drilling parameters and predict drill bit performance in a current well.

Abstract: Modified Drilling fluid compositions, lost circulation material compositions and methods for using drilling fluid compositions are provided with enhanced loss control properties where the modified drilling fluid may include a carrier fluid, one or more drilling fluid additives, and a lost circulation shape-adaptable material. The loss lost circulation shape-adaptable material may include a plurality of oval shaped composite particles, wherein the plurality of oval shaped composite particles comprise a first component, a second component, and a high temperature, high pressure (HTHP) binding adhesive. Methods to control lost circulation in a lost circulation zone in a wellbore may include introducing a modified drilling fluid into the wellbore such that the modified drilling fluid contacts the lost circulation zone.

Abstract: A drilling tool for drilling a wellbore in a formation, where the drilling tool includes: a drill bit comprising a cutting element, a sensor array, and a controller. The sensor array includes: an acoustic emissions (AE) sensor configured to measure an acoustic signal generated during drilling of the formation by the cutting element and a load sensor configured to measure an applied load by the cutting element on the formation. The controller is communicably connected to the sensor array and configured to determine a toughness of the cutting element using the acoustic signal, the applied load, and a wear state.

Abstract: A method includes utilizing a charging and communication interface and a sensor system to gather downhole measurements. The method further includes charging and activating the sensor system using the charging and communication interface, installing the sensor system into a nozzle of a drill bit, running the drill bit into a wellbore, conducting measurements using the sensor system, pulling the drill bit out of the wellbore, and contacting the charging and communication interface with the sensor system to retrieve the measurements from the sensor system.

Abstract: An apparatus includes an outer structure body having a cavity and an inner structure body rotatably supported within the cavity. The inner structure body has 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 are positioned to releasably contact and impart motion to the movable elements in response to relative motion between the inner structure body and the outer structure body. A plurality of triboelectric energy harvesters are positioned to generate electrical charges when motion is imparted to the movable elements by the ball elements.

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.
