A top drive system for wellbore related activities involving a drilling tubulars string. The system includes a frame structure and a top drive device with one or more top drive motors, a transmission housing, a floating quill system with a hollow vertical floating quill shaft. The top drive device has a thrust bearing housing arranged below the transmission housing and suspended via said first and second vertical frame members from the top frame member. A hollow vertical outer main shaft is suspended from the thrust bearing housing and a hollow vertical inner main shaft is arranged vertically mobile within the outer main shaft. The inner main shaft is connected to the floating quill shaft and has a lower connector end that is configured to be connected to a drilling tubulars string via a threaded connection, so as to allow for transmission of the rotary torque from the one or more top drive motors via the transmission, the floating quill shaft, the inner main shaft, to the threadedly connected drilling tubular string.

A tubular running tool equipped with a mandrel having an elongated body with a longitudinal axis and configured for suspension above a wellbore. A plurality of slips are disposed on the mandrel. Each slip is configured to receive and retain a swappable insert. Each swappable insert is configured with a gripping portion on a surface thereof. A sensor is configured to detect when a tubular is in a determined position to permit actuation of the mandrel to urge the slips radially outward such that the slips remain parallel to the longitudinal axis of the mandrel and the inserts are correspondingly urged radially outward. A method and system using the tool for running a tubular and providing a makeup torque.

A ground drilling device with a drivetrain for rotating a drill string, wherein at least one section of the drivetrain is configured to form a channel between a force transmission element of the drivetrain and the drill string, wherein the channel projects through the force transmission element and the force transmission element may be driven radially in the drivetrain.

A drill head position determination system may include a mast, a drill head movably attached to the mast, and a drill drive assembly configured to move the drill head up and down along a length of the mast. The drill head may be configured to rotate a drill string. The drill drive assembly may include at least one sheave and a cable system wound about the at least one sheave. The drill head position determination system may further include a sheave sensor operatively coupled to the at least one sheave and configured to determine a position of the drill head based on a measured rotational position of the at least one sheave.

A system for handling drill pipe on the exit side of the borehole in horizontal directional drilling operations. The system pulls the drill string out of the borehole and uses a top drive and pipe wrench to disconnect the individual segments of drill pipe from the drill string. Pipe gripping arms lift the disconnected drill pipe segment away from the rest of the drill string and release it into a nearby pipe rack. The components of the system are collapsible and can nest in one another during transport.

A single trip liner running and tie-back system is disclosed. The system includes a liner string to case a formation, a polished bore receptacle installed in a liner hanger, and a tie back casing string to tie back the liner string to a wellhead. The tie back casing string is fit with a seal assembly comprised of a no-go stopper, and the seal assembly of the tie back casing string is anchored inside the polished bore receptacle of the liner hanger to run the liner string and the tie back casing string in tandem.

A drive fluid inlet is at an uphole end of the submersible pump top drive. A removable hydraulic motor is driven by drive fluid received by the drive fluid inlet. The removable hydraulic motor is separable from a downhole pump. A receiver is at a downhole end of the hydraulic motor. The receiver is configured to mate with the downhole pump. A drive fluid outlet is configured to expel the drive fluid after the drive fluid has flowed through the hydraulic motor. The drive fluid outlet is downhole of the drive fluid inlet.

An apparatus for monitoring a power swivel system includes a smart box comprising a processing device electrically associated with a memory, communication technology and least one of a local display device or a remote display device where the communication technology. The smart box is associated with a power swivel system comprising a power swivel unit in fluid communication with a hydraulic pump system driven by a motor. The hydraulic pump system is configured to pump a hydraulic fluid through the power swivel unit to activate rotating elements. A plurality of sensors are connected to the processing device and various components of the power swivel system including the rotating elements to monitor such elements and minimize the possibility of an over speed and/or over torque condition. Data providing a status of the power swivel system components is transmitted to a remote device and presented to a user via a GUI.

A rotary latch release mechanism includes axially-aligned upper and lower rotary latch components carried on and rotationally coupled to upper and lower latch assemblies, respectively. The latch release mechanism is movable from an axially-latched position to an axially-unlatched position in response to relative rotation between the upper and lower rotary latch components. The latch release mechanism has a movable land surface that acts in response to relative axial displacement to induce the relative rotation required to release the latch. The latch release mechanism may be configured such that the axial movement of the movable land surface will cause the relative axial movement required to release the latch in combination with the required rotation. Accordingly, the rotary latch mechanism operates in response to externally-controlled axial movement of a movable land surface carried by the latch release mechanism, without requiring externally-induced rotation.

The present disclosure discloses a drilling machine. The drilling machine may include a base, a mast arranged on the base, an iron roughneck, a drill floor mechanical arm, a top drive arranged on the mast, a pipe racker on a finger board, a power finger board, a power catwalk arranged on the ground, and an elevator arranged on the top drive. The drill machine and a corresponding tripping out and tripping in method may be used to vertically transport a stand between a well center and a region of at least one pipe setback efficiently, which may improve the efficiency of tripping out and tripping in, and reduce the risk of accidents in the well. In addition, the present disclosure provides a corresponding method for offline connecting and disconnecting stands during a drilling operation, which may reduce a preparation time during the drilling, improve the drilling efficiency, and reduce the cost of oilfield development.
