Abstract: A downhole drilling tool, forming part of a subterranean drilling system, may include at least one plate secured to an exterior of an elongate body. Electronics may be disposed between the plate and the body to be protected by the plate while still readily accessible. A dynamic element may be radially extendable from the plate to engage an inner wall of a borehole being drilled. If this radially-extendable element becomes worn or damaged from this engagement, the plate may be replaced. More expensive components of the drilling tool may be contained within the elongate body, rather than the plate, thus reducing replacement frequency. Additionally, plates including unique features may be employed at different times without altering the underlying elongate body.

Abstract: A reamer includes a plurality of cutter pocket holders. The cutter pocket holders are separately manufactured and connected to a body of the reamer. The cutter pocket holders include a plurality of cutter pockets, into which cutting elements may be inserted. A radially rearward cutter pocket holder may include front-loading cutter pockets.

Abstract: A tool trap system includes a housing defining a bore, a shaft coupled to the housing, and a flapper and an actuation system coupled to the shaft. The flapper selectively obstructs the bore through the housing. The actuation system includes a lever coupled to and configured to rotate the shaft, a cylinder configured to contact the lever, a hydraulic cylinder, and a piston rod extending through the cylinder and the hydraulic cylinder. The cylinder is configured to move axially along a longitudinal axis of the cylinder to rotate the lever. In response to manual actuation of the tool trap system, the hydraulic cylinder remains in place as the cylinder moves axially. In response to powered actuation of the tool trap system, a fluid pumped into the hydraulic cylinder axially moves the hydraulic cylinder, and the piston rod remains in place as the cylinder moves axially.

Abstract: A method includes obtaining first data representing a subterranean domain, and creating a geotag associated with a three-dimensional location of interest in the subterranean domain and a feature at the location of interest.

The method also includes generating metadata describing a portion of the first data, the second data, or both, storing the geotag in a database including a plurality of geotags. The method may also include searching for an analog to the geotag.

Abstract: A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.

Abstract: A cutting element includes a body, a non-planar cutting face formed on a first end of the body, and an edge formed around a perimeter of the cutting face. The cutting face includes a central raised portion, and the edge has an edge angle defined between the cutting face and a side surface of the body. The edge angle varies around the perimeter of the cutting face and includes an acute edge angle defined by a portion of the cutting face extending downwardly from the edge to a depth from the cutting angle. The portion of the edge defining the acute edge angle may be directly adjacent: a side surface of the cutting element; a bevel of the cutting element; or a flat region at the perimeter of the cutting element or bevel.

Abstract: A scratch tester has at least one cutter that moves simultaneously both rotationally and axially relative to the rock it is cutting. When rotational and axial movements are constant, the cutter generates a helical groove in the rock. In borehole embodiments, the scratch tester is fixed at a desired location using centralizers, and the cutter is provided on a motorized platform/track that translates between the centralizers and rotates around a central axis. The cutter faces outward and extends via a cutter arm to engage and carve a helical groove in the borehole wall. A laboratory scratch tester includes a holder for a solid cylindrical core sample and a motorized translating frame on which a cutter extends. The cutter is directed toward the core sample, and the holder with the core sample is rotated by a motor so that as the cutter translates relative thereto, a helical groove is cut thereinto.

The first model is not based on the new measurement data. Further, the method includes determining an enhanced control parameter based on the second model, determining an enhanced value corresponding to the second model using the enhanced control parameter, determining a realized value corresponding to the second model using the baseline control parameter, and calculating a value of the new measurement data by comparing the enhanced value and the realized value.

An example method includes commencing operation of a processing device to operate a system for maintaining safety of a human worker in a restricted area of a drill floor during drilling operations. The processing device may receive a presence detection signal and output a first stop control command to the equipment to cause the equipment to stop operating. The processing device may receive an entry request signal, output an entry request indicator via an output device to a human driller within a drill rig control center, receive an entry grant input from the human driller granting entry to the human worker to enter the restricted area, and output a second stop control command to the equipment located in the restricted area to cause the equipment to stop operating in response to the received entry grant input.

Abstract: An improved approach to creating a plan for a well. A user receives an initial well plan for a planned well and uses the initial well plan as a starting point for alternate well plans. This is done by creating a copy of the initial well plan, allowing the various uses to make changes to the initial well plan, and executing various automatic validation routines on the alternate designs. These validation routines can provide estimated times and costs to complete the planned well use the alternate well plan. The approach can also involved displaying the estimated times and costs of the different candidate well plans. The user can then select one of the candidate well plans as the master well plan. As replanning is done during the operations, this replanning information, along with the actual executed actions, is captured and stored.

Abstract: A technique facilitates use of an inductive coupler assembly with casing, e.g. well casing. An inductive coupler is formed as a female inductive coupler with an inductive coil. The inductive coupler is constructed for sliding movement along an exterior of the casing so that it may ultimately be positioned and secured at a suitable location along the casing. The inductive coupler is designed for connection with an electrical device, e.g. a sensor. The inductive coupler facilitates the transfer of sensor data and/or power signals across the casing. Signal transfer across the casing is further enabled by a male inductive coupler positioned within the casing at a location which allows it to cooperate with the exterior, female inductive coupler.
