Abstract: A bit used in a downhole environment has an active element that is movable relative to the bit. The bit is rotated in the downhole environment, and at least one downhole parameter is measured. The at least one downhole parameter is compared against a target parameter value, and when the at least one downhole parameter is beyond a threshold value of the target parameter value, the active element is selectively relative to the bit. Movement of the active element alters the proportion of the weight on the active element as compared to the other cutting structure of the bit. Changing the proportion of weight can be used to reduce the depth of cut of the cutting structure and to reduce or eliminate motor stall or stick-slip behavior.

Abstract: A drill bit includes a bit body with high and low fluid pressure bodies. The low-ressure bit body includes a fixed cutting structure, and the high-pressure bit body includes at least one high-pressure fluid channel and nozzle capable of withstanding fluid pressures greater than 40 kpsi (276 MPa). A bottomhole assembly includes a drill bit with a bit body having fixed cutter and fluid jetting portions. Low and high-pressure channels in the bit body exit in the fixed cutter and fluid jetting portions. A high-pressure nozzle is coupled to the fluid jetting portion and the high-pressure fluid channel, and a plurality of fixed cutting elements are coupled to the fixed cutter portion. A pressure intensifier is coupled to the drill bit and is configured to increase a pressure of a fluid supplied to the high-pressure fluid channel in the bit body.

Abstract: A cutting bit includes a bit body and high-pressure body with a high-pressure fluid conduit therethrough. The high-pressure body and bit body are joined together. The high-pressure fluid conduit is configured to convey a fluid at greater than 14.5 ksi, and in some embodiments greater than 40 ksi. The high-pressure fluid conduit may direct the fluid through a nozzle in a fluid jet to weaken material, such as an earth formation. The cutting bit includes at least one roller cone and/or blades with cutting elements thereon to remove the weakened material. A cutting bit includes both high and low-pressure fluid conduits, and high and low-pressure fluid nozzles. The high-pressure nozzles receive fluid flow from a downhole pressure intensifier, and a connection between the bit and the downhole pressure intensifier includes rigid connectors, flexible connectors, or a combination thereof.

Abstract: A torsional damping system includes a housing having an interior space. An inertia ring is located in the interior space, and a torsion fluid is located between the inertia ring and the housing. The inertia ring is rotatably installed relative to the housing. As the housing oscillates, the inertia ring damps at least a portion of the oscillation. The torsional damping system may be included in a downhole tool or bottomhole assembly, and used to damp oscillations along a drill string or along the bottomhole assembly, including between a downhole motor and a cutting tool.

Abstract: A method for drilling includes obtaining formation-measurement pairings, training a machine-learning model using the formation-measurement pairings, receiving measurements obtained by a tool positioned in a well formed in a formation, and generating a formation model of at least a portion of the formation using the machine-learning model and the measurements. The formation model represents one or more physical parameters of the formation, one or more structural parameters of the formation, or both.

Abstract: Systems and methods discussed herein relate to applying models to downhole tool records to identify, sort, and display a subset of available downhole tool records with index information as defined by the models that have a desired relationship with a received input. The received input may be indicative of a particular device, device family, or set of features for a downhole tool. The methods may include identifying, from a set of design information stored in computer-storage media, one or more downhole tool records that correspond to the received input, applying one or more index models to the identified one or more downhole tool records, applying one or more local models to the identified one or more downhole tool records, and displaying at least some of the one or more downhole tool records, with index information as defined by the one or more index and local models.
