A method and apparatus for local hydraulic power generation on an electric tong, including a power tong for spinning tubulars; a first electric motor functionally connected to the power tong; a plurality of hydraulic power consumers including a backup tong for clamping a tubular string; a second electric motor functionally connected to the plurality of hydraulic power consumers; electronics to drive the first electric motor and the second electric motor; and a switchbox providing at least two configurations of the system. A method includes arranging a tong system in a hydraulic power configuration; supplying hydraulic power with an onboard electric motor to at least one of a plurality of hydraulic power consumers to position a tubular for make-up; arranging the tong system in a rotary drive configuration; supplying at least one of torque and rotation with the onboard electric motor to a power tong.

Electric tong with onboard hydraulic power unit

Equipment and methods for coupling a top drive to one or more tools to facilitate data and/or signal transfer therebetween include a receiver assembly connectable to a top drive; a tool adapter connectable to a tool string, wherein a coupling between the receiver assembly and the tool adapter transfers at least one of torque and load therebetween; and a stationary data uplink comprising at least one of: a data swivel coupled to the receiver assembly; a wireless module coupled to the tool adapter; and a wireless transceiver coupled to the tool adapter. Equipment and methods include coupling a receiver assembly to a tool adapter to transfer at least one of torque and load therebetween, the tool adapter being connected to the tool string; collecting data at one or more points proximal the tool string; and communicating the data to a stationary computer while rotating the tool adapter.

Tool coupler with data and signal transfer methods for top drive

Methods and systems for controlling a set of tools for hydrocarbon recovery are presented. One example system generally includes a first tool and a first control device mounted on the first tool and configured to operate the first tool. The first control device includes an explosion-proof housing and a processor disposed in the housing. The system further includes a second tool and a second control device mounted on the second tool and configured to operate the second tool. The second control device includes an explosion-proof housing and a processor disposed in the housing.

Control system for hydrocarbon recovery tools

Embodiments of the present disclosure relate to apparatus and methods for making up and evaluating tubular threaded connections. A tong assembly may be used for making up threaded connections. A threaded connection may be made up automatically by controlling the rotation speed of the tong assembly according to measurements of torque, turns, and/or time. After a threaded connection is made up, measurements of time, torque, and/or turns may be corrected based on operating parameters. The corrected measurements may be evaluated for indications of failure, such as discontinuity, torque spikes, and torque drops. The threaded connection is then accepted or rejected based on the evaluation.

Autonomous connection makeup and evaluation

A top drive unit including a top drive housing, a drive stem disposed in the top drive housing, a carrier configured to axially move the drive stem relative to the top drive housing, and a drive mechanism for rotating the drive stem.

Compensated top drive unit and elevator links

A method of making a connection between a first tubular and a second tubular includes gripping the first tubular using a power tong; gripping the second tubular using a backup tong; applying a torque to the first tubular using a power tong; and moving the power tong at a predetermined speed to compensate for a weight of the power tong.

Compensation system for a tong assembly

The present disclosure generally relates to a tong assembly having position sensors for controlling door opening and closing sequence. The tong assembly includes a back section, an outer door section movably coupled to the back section, a first actuator configured to move the outer door section between an open position and a closed position, an inner door section movably coupled to the back section, a second actuator configured to move the inner door section between an open position and a closed position, a first sensor positioned to measure a position of the outer door section; and a second sensor positioned to measure a position of the inner door section.

Tong assembly with door position sensors

A method for connecting a tong cassette and a positioning device includes moving a positioning arm of the positioning device toward a predetermined position on the rig; identifying a position of the tong cassette relative to the positioning arm; and connecting the positioning arm to the tong cassette. A system includes a tong cassette; and a positioning device having a first sensor configured to measure a distance between the tong cassette and the positioning device; and a second sensor configured to measure a stick-up height of a tubular string.

Tong cassette positioning device

A tong includes a frame having jaws configured to engage a tubular and a tong control assembly disposed on the frame. The tong control assembly includes a housing connected to the frame, a shutoff switch, and a toggle lever located at a suitable position on the housing, whereby the toggle lever is configured to be operated while the shutoff switch is depressed, and wherein the toggle lever is configured to control at least one of: a rotational speed of the jaws and a rotational direction of the jaws. A method of operating a tong includes clamping a first tubular using first jaws of a tong, clamping a second tubular using second jaws of the tong, rotating the first tubular relative to the second tubular, and controlling a rotational speed of the first tubular using a toggle lever disposed on a frame of the tong.

Apparatus and methods for tong operation

Methods and systems for connecting threaded tubulars are presented. One example method generally includes monitoring relative rotation between a backup tong and a tubular clamped in the backup tong to determine slippage of the backup tong.

Method and system for evaluating tubular makeup

An electronic control system comprises a first tubular handling tool, a sensor, and a controller. The controller is configured to control actuation of the first tubular handling tool in response to an electronic signal received from the sensor that corresponds to an operational characteristic of the first tubular handling tool. The electronic control system functions as an electronic interlock system to prevent mishandling of a tubular. A method of controlling a tubular handling tool comprises measuring an operational characteristic of the tubular handling tool, communicating the operational characteristic to a controller in the form of an electronic signal, and using the controller to control actuation of the tubular handling tool in response to the measured operational characteristic.
