An apparatus includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine a target position for a drill bit of the track-mounted drill rig; determine a turning trajectory of an aiming point of the drill bit; monitor position of the turning trajectory of the aiming point of the drill bit with respect to the target position of the drill bit during approach of the track-mounted drill rig to the target position; and cause turning of the track-mounted drill rig to align the aiming point of the drill bit with the target position of the drill bit based on determining that the turning trajectory of the aiming point of the drill bit substantially coincides with the target position of the drill bit.

A directional drill securing device and associated methods are shown. Securing devices and methods shown include a plurality of staking devices on a single lateral side of a directional drill. Using examples shown, a lower force is required to drive multiple staking devices than would be needed for a larger staking device of equivalent area.

A hydraulic collapsible rotary stand for a wireline coring underground drill rig includes two main hydraulic supporting posts, at least one hydraulic post erection cylinder, a collapsible stand base, a horizontal rotating base, and a rotary lifting cylinder, where the rotary lifting cylinder drives the collapsible stand base to move up or down; post mounting rods are hinged at a front side of the collapsible stand base; the post mounting rods are respectively connected to the main hydraulic supporting posts; a main post supporting cross-bar is provided between the main hydraulic supporting posts; through the hydraulic post erection cylinder, the main post supporting cross-bar is supported and the main hydraulic supporting post is pushed to be erected or collapsed; a hydraulic gyration supporting beam is provided between the main hydraulic supporting posts; and the hydraulic gyration supporting beam is connected to a lower sliding plate provided with a drill rig.

Provided is a wellbore tractor and method for operating a well system. The wellbore tractor, in one aspect, includes a base member, and one or more turbines fixed to the base member for rotating the base member in a first rotational direction based upon a first direction of fluid flow. The wellbore tractor, according to this aspect, further includes one or more wellbore engaging devices radially extending from the base member, the one or more wellbore engaging devices contactable with a surface of a wellbore for displacing the base member and one or more turbines axially downhole as the one or more turbines rotate in the first rotational direction.

A directional drill vice and associated methods are shown. A directional drill and associated methods are also shown. Examples of directional drill stem configurations include gripping jaws configured with a common jaw pivot. Examples of directional drill stem configurations also include a slot in a vice frame to allow lateral insertion of a drill stem segment.

A communication system (10) for an underground production drill (8), comprising a slave unit (12) comprising a CAN bus interface (14) and an electrical power controller (16) and rechargeable battery (18), said controller (16) configured to monitor a status and regulate charging of said battery (18). The controller (16) and battery (18) encapsulated in a thermally-conductive fire retardant material (10). The slave unit (12) includes a first protocol converter (24) and powered via the power controller (16) and configured to convert between wireless network and CAN bus protocols, and a first wireless transceiver (26) arranged in signal communication with the power controller (16) and first protocol converter (24) and configured to transceive the wireless network protocol and transmit the status of the battery (18). System (10) includes a master unit (28) comprising a CAN bus interface (14), a second protocol converter (30) and a second wireless transceiver (32).

A mobile well rig can include a mast, an anchor that connects to a flange of a wellhead assembly, and a tensile member that transfers tensile loads between the wellhead assembly and the mast. A method of securing a mobile well rig to a wellhead assembly can include connecting an anchor to the wellhead assembly, connecting a tensile member to the anchor, and connecting the tensile member to a mast of the mobile well rig. A securement system can include an anchor secured to a wellhead assembly, a tensile member that transfers a tensile load between the wellhead assembly and a mast of a mobile well rig, and a strut that transfers a compressive load between the wellhead assembly and the mast.

A well rig can include a mast, and multiple guide assemblies distributed along the mast. The guide assemblies are configured to laterally support a tubular string. A method of operating a well rig can include mounting multiple guide assemblies spaced apart along a length of a mast of the well rig, and actuating each of the guide assemblies between open and closed configurations. In the open configuration the guide assembly does not laterally support a tubular string, and in the closed configuration the guide assembly laterally supports the tubular string. Another method can include mounting multiple guide assemblies spaced apart along a length of a mast of a well rig, and displacing a top drive along the mast. The guide assemblies open in succession as the top drive descends along the mast, and the guide assemblies close in succession as the top drive ascends along the mast.

A well rig can include a mast, and a strut assembly connected to the mast for transmitting a compressive load between the mast and a wellhead assembly, the strut assembly including an anchor that connects to an upper flange of the wellhead assembly. A method of aligning a well rig with a wellhead assembly can include raising a mast of the well rig, and deploying a strut assembly, thereby positioning an anchor relative to the mast. Another well rig can include a mast, and a strut assembly connected to the mast and including struts that transmit a compressive load between the mast and a wellhead assembly, the strut assembly further including an anchor that connects to the wellhead assembly, and the anchor including a rotatable flange body.
