Abstract: A system for a drilling rig, a computer-readable medium, and a method for tracking an oilfield tubular. The method includes applying a tag to the oilfield tubular, the tag including a readable tag identifier, determining a physical parameter of the oilfield tubular, storing data representing the physical parameter in association with the tag identifier in a database, reading the tag identifier from the tag applied to the oilfield tubular, prior to deploying the oilfield tubular into a wellbore, and generating a pipe tally comprising data representing a plurality of oilfield tubulars, including the oilfield tubular, connected together and deployed into the wellbore using a drilling rig.

Abstract: A top-drive system and a drilling rig. The top-drive system includes a sheave configured to receive a drilling line, a frame coupled with the sheave and configured to transmit a weight of a tubular string suspended therefrom to the sheave, a controller, and a sensor in communication with the controller. The sensor is configured to directly measure one or more physical parameters of a drilling operation and provide data representing the one or more physical parameters to the controller.

Abstract: Pipes, drill strings including pipes, and methods for use on a drilling rig. The method includes obtaining pipe data for individual drill pipes of a drill string, obtaining a well trajectory for a well, obtaining one or more drilling measurements to be used when drilling the well, planning a first drill string based on the pipe data, the well trajectory, and the one or more drilling measurements, predicting an aging of the individual drill pipes in the first drill string while drilling the well using the first drill string, determining that a risk of failure of one or more individual pipes in the first drill string is unacceptable based on the aging of the individual pipes; and planning a second drill string in response to determining that the risk of failure is unacceptable in the first drill string.

Abstract: A reamer for enlarging an underground borehole comprises a plurality of cutter assemblies distributed azimuthally around a longitudinal axis of the tool. Each cutter assembly comprises a supporting structure and a plurality of hard faced cutters secured therein with a hard surface of each cutter exposed and facing in a direction of rotation of the tool and extending radially outwards from the tool axis to a radially outward extremity. These cutters are arranged in a sequence extending axially along the tool. In contrast with convention a1 cutter assemblies, the supporting structure comprises at least one radially outward-facing surface which is positioned to follow behind the leading face of at least one cutter as the tool rotates and which is aligned with the radially outer extremity of the cutter at the same radial distance from the tool axis. Thus the surface area available to contact the borehole wall and stabilise the positioning and motion of the rotating reamer is enhanced.

Abstract: Systems and methods for drilling a wellbore. The method includes measuring a first distance that a drilling device is raised while connected to a drill string, determining a weight-on-bit in the drill string, determining a second distance to lower the drilling device such that a drill bit at a lower extremity of the drill string approaches toward a bottom of the wellbore, based on the first distance and the weight-on-bit, and lowering the drilling device by the second distance.

Abstract: A method of imaging an earth formation comprises identifying engagement data from an engagement sensor. The engagement data corresponds to an engagement of the instrumented engagement element with a borehole in the earth formation. The method includes identifying rotation data from a rotation sensor. The rotation data corresponds to a rotational orientation of the engagement data with respect to the borehole. The method includes mapping the engagement data to the rotation data to generate oriented engagement data.

Abstract: A reaming tool for enlarging an underground borehole comprises a plurality of cutter assemblies (251, 252, 253) distributed azimuthally around a longitudinal axis of the tool, wherein each cutter assembly comprises support structure bearing a sequence of cutters (211-214) with leading surfaces facing in a direction of rotation of the tool and the sequence of cutters extends axially along the tool from an axial end (202) of the tool with the cutters positioned at radial distances from the tool axis which progressively increase as the sequence extends away from the axial end of the tool. The cutter assemblies include guiding structure (261-264) which is positioned circumferentially ahead of the leading faces of cutters of the sequence on the assembly. This guiding structure is configured such that the outline of the guiding structure is able to coincide with at least part of the notional surface described by the cutting outline of the preceding cutter assembly as the tool rotates, without any part of the guiding structure projecting outside that notional surface. This stabilises the positioning of the rotating tool in the borehole.
