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: The operation of rotary equipment carried on elongate structure such as coiled tubing extending into a borehole from the Earth's surface is carried out by providing at least one optical fibre extending downhole to the rotary equipment from the surface, using optical time domain reflectometry to operating the optical fibre as a distributed vibration sensor while the rotary equipment is in operation, and thereby observing vibration created by the rotary equipment.

Abstract: Wear sensors are provided on a drill bit or other rotary cutting tool which is for operation in a subterranean borehole and has a plurality of separate cutters protruding from a support structure towards the material to be cut by the tool. The electrically operated sensing means are located at or coupled to a sensing point within a protrusion from the support structure. This sensing point is located within a protrusion such that attrition of at least one cutter to a partially worn state brings the protrusion into abrasive contact with the material being cut and attrition of the protrusion then exposes the sensing point to the material which is being cut by the tool and thereby brings about a detectable change, which may include damage to the sensor at the sensing point, indicative of wear. The tool includes means to communicate data from the sensing means to the surface.

Abstract: Systems and methods for tracking depth of a drill string. The method includes determining a measured elevation difference between a first position of a sensor and a second position of the sensor, based on measurements taken by an elevation measurement device, determining a calibration elevation difference between the first and second positions based on measurements taken by the sensor using markers positioned at predetermined elevations, and calibrating the elevation measurement device based at least partially on a relationship between the measured elevation difference and the calibration elevation difference.

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.

Abstract: A reaming tool for enlarging an underground borehole comprises a plurality of cutter assemblies distributed azimuthally around a longitudinal axis of the tool, wherein each cutter assembly includes a supporting structure bearing a sequence of cutters which have hard surfaces exposed and facing in a direction of rotation of the tool. The outer surface of the support structure on each cutter assembly includes zones which each face towards an end of the assembly and is configured such that as it extends circumferentially relative to the tool axis in the direction opposite to rotation of the tool, it also extends away from an end of the assembly.
