A drilling rig having a lift arm, which may be an auxiliary lift arm provided in addition to a primary lifting cable system of the drilling rig. The lift arm may be configured to hoist and/or manipulate drill collar, drill pipe, or other drilling pipe or conduit. The lift arm may be coupled to a mast of the drilling rig and may have a cantilevered boom extending therefrom. The boom may be configured to pivot between alignment, or near alignment, with well center and a racking board. The lift arm may additionally have a pipe engaging element coupled to the boom. The pipe engaging element may be configured to couple to stands or lengths of drilling pipe. The pipe engaging element may be raised and lowered together with or relative to the boom via a lift line controllable via a hydraulic cylinder, winch, or other suitable mechanism for withdrawing and releasing the line.

The disclosure provides a movement monitor for detecting movement of downhole equipment in a wellbore during, for example, installation of the equipment. A method of installing downhole equipment in a wellbore and a system for the installation is also disclosed. In one example, the movement monitor includes: (1) a communications interface configured to provide movement information corresponding to downhole equipment in a wellbore, wherein the downhole equipment is attached to a cable, and (2) a rotation detector configured to generate rotational data associated with movement of the downhole equipment within the wellbore, wherein the movement information corresponds to the rotational data and the rotational data is based on a rotating device in contact with a tensioned-portion of the cable.

A vibratory grouting drilling rig includes: a drilling rig bracket, a moving bracket, and a driving mechanism mounted on the drilling rig bracket for driving the moving bracket to move; wherein a working bracket is slidingly mounted on the moving bracket, and a sliding direction of the working bracket is identical to a moving direction of the moving bracket; a vibratory grouting rod and a drilling rod are mounted on the working bracket; multiple flexible connectors are connected between the working bracket and the drilling rig bracket, and are arranged along the moving direction of the moving bracket; the flexible connectors go around an end of the moving bracket and are connected to the drilling rig bracket. When the moving bracket moves, the flexible connectors pull the working bracket to move relative to the moving bracket, thus providing extra drilling force.

A wireline apparatus is for moving a tool into or out of a well. The apparatus is configured for forming a pressure vessel in combination with at least a portion of the well. The apparatus has: a first compartment for forming part of the pressure vessel; a hoisting means, the hoisting means being placed inside the first compartment; a wireline connected to the hoisting means; a second compartment arranged inside the first compartment; an electrical motor for driving the hoisting means, the electrical motor placed inside the second compartment; and a drive shaft for connecting the motor to the hoisting means, the drive shaft extending from the motor to the hoisting means through a wall separating the first compartment and second compartment. A method is for moving the tool in the well.

A trigger mechanism is provided for a passive rotating jointed tubing injector having gripper blocks for moving connected, segmented oilfield tubulars axially into or out of horizontal, extended-reach oil and natural gas wells that may contain pressurized fluid or gas to complete for production, work over and service the wells, utilizing an operation commonly known as snubbing. The trigger mechanism can open the gripper blocks when a tapered upset section of increasing diameter on the tubulars is encountered that would not otherwise fully open and operate the gripper blocks.

Systems and methods for safe drill floor access. An example method includes commencing operation of a processing device to operate a system for maintaining safety of a human worker in a restricted area of a drill floor during drilling operations. The processing device may receive a presence detection signal and output a first stop control command to the equipment to cause the equipment to stop operating. The processing device may receive an entry request signal, output an entry request indicator via an output device to a human driller within a drill rig control center, receive an entry grant input from the human driller granting entry to the human worker to enter the restricted area, and output a second stop control command to the equipment located in the restricted area to cause the equipment to stop operating in response to the received entry grant input.
