Abstract: An extrudable ball seat (36) is configured to be secured along a well tubing (34). The extrudable ball seat (36) comprises a larger diameter section (42) and a smaller diameter (44) section connected by a conical section (46). The conical section (46) has an internal seating surface (48) for receiving a corresponding element, e.g. a ball (52), in sealing engagement. The extrudable ball seat (36) facilitates controlled extrusion of the element following a pressure actuation procedure by providing the smaller diameter section (44) with sufficient ductility to enable extrusion of the element under an increased predetermined pressure. Additionally, the extrudable ball seat comprises at least one notch (56), e.g. a plurality of grooves (58), positioned to initiate crack propagation and thus extrusion of larger elements.

Abstract: Systems, computer-readable media, and methods for valuating measurement data, of which the method includes obtaining a first model of a subsurface volume, determining a baseline control parameter based on the first model, receiving new measurement data measured using a data collection device, the new measurement data representing one or more characteristics of the subsurface volume, and obtaining a second model of the subsurface volume based in part on the new measurement data. 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.

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 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 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 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.
