Abstract: An apparatus and method are used in conjunction with a system for performing horizontal directional drilling, the system including a drill string extending from a drill rig to a boring tool such that the boring tool is steerable based on a roll orientation. The system also includes an arrangement for generating steering commands for guiding the boring tool to a target position. Responsive at least in part to the steering commands, a display is configured to selectively indicate each of a rotate command, a push command and a spin command. A steering indicator is described which indicates a current roll orientation of the boring tool. A 3-D grid can be animated and centered on either a steering or target indicator. Rounding of a steering command ratio can limit the display of target roll orientations to only those that a given boring tool transmitter is capable of sensing and indicating.

Abstract: A signal acquisition method of an azimuthal electromagnetic wave resistivity instrument includes receiving, by a receiving antenna, a magnetic induction signal after formation attenuation, and converting the received magnetic induction signal into an electrical signal; amplifying, by a preamplifier circuit, a fixed gain of a received signal with nV level amplitude induced on the receiving antenna; controlling a filtering circuit to filter the amplified signal; amplifying the filtered signal using a programmable amplifier circuit to generate a target signal; and conducting digital conversion for the target signal that meets the requirements of low-frequency acquisition.

Abstract: Systems, apparatus and methods are described for purposes of initiating a response to detection of an adverse operational condition involving a system including a drill rig and an inground tool. The response can be based on an uphole sensed parameter in combination with a downhole sensed parameter. The adverse operational condition can involve cross-bore detection, frac-out detection, excessive downhole pressure, a plugged jet indication and drill string key-holing detection. A communication system includes an inground communication link that allows bidirectional communication between a walkover detector and the drill rig via the inground tool. Monitoring of inground tool depth and/or lateral movement can be performed using techniques that approach integrated values. Bit force based auto-carving is described in the context of an automated procedure.

Abstract: A method, device, and system is described herein for pushing a rotary drill bit. Pushing the rotary drill bit can include receiving a target direction in a formation to push the rotary drill bit while drilling a wellbore in a formation. Pushing the rotary drill bit can also include opening, at a first rotational position of a rotary bit pushing device disposed proximate to the rotary drill bit within the wellbore, a first inlet port of a first flow regulator. Pushing the rotary drill bit can further include closing, after the first rotational position of the rotary bit pushing device, the first inlet port. Pushing the rotary drill bit can also include sending, to a second flow regulator of the rotary bit pushing device, a second quantity of drilling fluid.

Abstract: Method(s) and apparatus according to which: a bottom-hole assembly (“BHA”) and a drilling rig together attempt to drill a wellbore segment along a planned trajectory while a test scenario is executed on the drilling rig by varying operating parameter(s) of the drilling rig in a predetermined manner during a predetermined time interval; performance characteristic(s) monitored by sensor(s) of the BHA during the predetermined time interval are then received; the predetermined manner in which the operating parameter(s) of the drilling rig were varied during the predetermined time interval is/are then compared to the received performance characteristic(s) monitored by the sensor(s) of the BHA during the predetermined time interval; and based on said comparison, the operating parameter(s) of a drilling rig (e.g., another drilling rig) are controlled while a BHA (e.g., another BHA) operably associated with the drilling rig attempts to drill a wellbore segment along a similar planned trajectory.
