A washing and doping mechanism includes a bushing that is configured to engage a tubular that is in a substantially vertical orientation. The bushing is configured to rotate, thereby causing the tubular to rotate about a central longitudinal axis of the tubular. The washing and doping mechanism also includes a sprayer configured to spray a fluid onto the tubular in the substantially vertical orientation.

System and method for washing and doping oilfield tubulars

A stand-building system and method for a drilling rig, of which the system includes a casing preparation skid configured to prepare a casing joint for connection to another casing joint, and a casing stand assembly skid configured to receive the prepared casing joint and to connect together the prepared casing joint with one or more other joints so as to form a casing stand. The casing preparing skid and the casing stand assembly skid are horizontally aligned with and extend parallel to one another and to a catwalk of the drilling rig, and the casing stand assembly skid is configured to deliver the casing stand to the catwalk.

Horizontal off-rig casing and drill pipe assembly

A method sequence for handling tubulars into or out of a wellbore, the method comprising: moving a tubular string into or out of a wellbore via a top drive; moving tubular stands to and from a setback position and a stand handoff position via a transfer bridge racker and a setback guide arm; moving tubular stands to and from the stand handoff position and a well center position via a tubular delivery arm and a lower stabilizing arm; building stands and breaking down stands offline via a mousehole and operating a roughneck on joints between the tubular stands and the tubular string.

Sequencing for pipe handling

A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/disengaging the top drive and a stand constrained by the clasp.

High trip rate drilling rig

A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end.

Tubular delivery arm for a drilling rig

A retractable top drive for use with a drilling rig and process for operating a drilling rig. The retractable top drive comprises a dolly having a pair of mast rails in translatable relation to a mast, such as sliding. A yoke pivotally connects a torque tube to the dolly and the top drive is connected to the torque tube, so that a substantial portion of the top drive is positioned lower than a substantial portion of the dolly. An extendable actuator is connected between the dolly and the yoke to translate the top drive to/from the dolly. Torque is transferred from the top drive through the torque tube, yoke and dolly into the mast of the drill rig.

Retractable top drive with torque tube

A thread compensator for performing casing running operations. An example method may include visually ascertaining operational parameters of a thread compensator displayed on a video output device. The thread compensator may be connected between a top drive and a travelling block, and a casing running tool may be connected to the top drive. The operational parameters may include the height that the top drive is lifted by the thread compensator and force applied to casing by the top drive. The method may further comprise manually controlling well construction equipment to perform casing running operations based on the ascertained operational parameters.

A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/dis engaging the top drive and a stand constrained by the clasp.

A workstation system for monitoring and controlling subsystems on a drilling rig, the system comprising: first and second workstation alcoves positioned near a drill rig floor so as to provide operators with direct lines of sight while sitting or standing in the alcoves to control drill rig subsystems, wherein each of the first and second workstation alcoves comprise: an operator chair; a plurality of controls for controlling the at least one first drill rig subsystem; at least one display of a graphical representation of the at least one first drill rig subsystem.

Driller's control station

The present disclosure introduces apparatus and related methods pertaining to a first electrical power cable, a second electrical power cable, and a set of breakers. The first and second electrical power cables each extend a variable distance between a static system at a wellsite and a movable system at the wellsite. The breakers are operable to select either of the first and second electrical power cables to couple electrical power from a stationary electrical power source at the static system to a load at the movable system.

Electrical power transmission for well construction apparatus

A catwalk and crane system for transporting equipment of a well system includes a substructure, a directing frame pivotally coupled to the substructure, a pipe transporter configured to transport a tubular along the directing frame, a first actuator coupled to the directing frame and configured to rotate the directing frame relative to the substructure, and a crane coupled to the directing frame, wherein the crane is extendable from a first end of the directing frame.

Catwalk and crane system

A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end. The dolly vertically translates the front side of the mast in response to actuation of a hoist at the crown of the mast. The tubular delivery arm translates the mast in non-conflicting passage of a top drive connected to the same mast, for positioning a tubular stand over the centerline of the wellbore, a mousehole, or a stand hand-off position.
