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.

Abstract: A system can calibrate inconsistencies in a wellbore tool. The system can receive a first set of measurements and a second set of measurements with respect to different electromagnetic antennas. The system can decouple a first multi-components tensor corresponding to the first set of measurements and a second multi-components tensor corresponding to the second set of measurements. The system can determine, using the decoupled first and second multi-components tensors, a scaling factor. The system can apply the scaling factor to a raw measurement received with respect to an electromagnetic antenna of the wellbore tool positioned in a wellbore to decouple a third multi-components tensor or to decoupled components of a fourth multi-components tensor for controlling a wellbore operation.

Abstract: A system and method for drilling are provided. Responsive to receipt of information, the system determines an estimated position of a drill bit in a borehole and whether the estimated position is within a defined margin of error on the planned path. If the estimated position is not within the defined margin of error, the system calculates a first plurality of convergence plans, each defining a path from the estimated position to the planned path or from a projected position of the drill bit. The system defines a second plurality of convergence plans defining a subset of the first plurality, each falling within a window of correction. The system selects a convergence plan from the second plurality that optimizes target parameters and produces control parameters associated with drilling the selected plan. The system drills at least a portion of the borehole based on the produced control parameters.

Abstract: Disclosed herein are systems and methods for automating a pump-down stop operation and, more particularly, example embodiments may include an automated pump-down stop system that adjusts a fluid rate and a winch speed before the target depth based on the remaining depth and line speed. An example method for automating a pump-down stop operation of a downhole tool string includes: measuring a depth of the downhole tool string, wherein the downhole tool string is held by a wireline; measuring a wireline tension; measuring a speed of the wireline; measuring a pumping rate; measuring an inclination of the downhole tool string; and regulating automatically a winch controller and a pump controller simultaneously to stop the downhole tool string at a target depth based at least on the measurements of one or more of the depth, wireline tension, speed, pumping rate, and/or inclination.

Abstract: Various implementations directed to a system and method for using a magnetometer in a gyro-while-drilling (GWD) survey tool are provided. In one implementation, a method may include acquiring gyroscopic data using gyroscopic sensors of a GWD survey tool while the tool is disposed at a first position within a wellbore. The method may also include acquiring first magnetic data using a magnetometer of the GWD survey tool while the tool is disposed at the first position. The method may further include determining an offset value for the magnetometer based on the gyroscopic data and the first magnetic data. The method may additionally include acquiring second magnetic data using the magnetometer while the tool is disposed at second positions within the wellbore. The method may also include determining magnetic azimuth values for the tool disposed at the second positions based on the second magnetic data and the offset value.

Abstract: The present invention is directed to an apparatus for use on a structural member having a longitudinal axis. The structural member conducts a pressurized fluid in an operational state. The apparatus includes a housing member having a first end, a second end, and at least one protective enclosure configured to accommodate at least one device. The housing member moves on the structural member parallel to the longitudinal axis in the operational state with a substantially frictionless reciprocating motion. The housing member is rotationally registered to the structural member when coupled thereto. A first pneumatic isolator is formed at the first end and receives a first pressurized fluid portion of the pressurized fluid in the operational state to thus drive the housing member toward a second direction of the substantially frictionless reciprocating motion. A second pneumatic isolator is formed at the second end and receives a second pressurized fluid portion of the pressurized fluid in the operational state to thus drive the housing member toward a first direction of the substantially frictionless reciprocating motion opposite the second direction. The substantially frictionless reciprocating motion is a function of external stimuli, the first pressurized fluid portion and the second pressurized fluid portion such that the housing member is substantially isolated from the external stimuli.
