A tubular rotating system for rotating threaded tubulars is provided. The system includes a frame, a plurality of rollers coupled to the frame and configured to rotate a tubular, and a control valve coupled to the frame and configured to control a rotational speed of the rollers. The control valve controls an amount of air, fluid, or electric power supplied to the system based on tension applied to the system to thereby control the speed at which the rollers rotate.

The invention relates to a working machine and a method for working the ground with the working machine, having a mast, along which, by means of a positioning means, a power rotary head is moved vertically, by which a telescopic Kelly rod having at least two Kelly bars is displaced and guided, wherein, for the purpose of torque transmission, the Kelly bars are provided on their external and/or internal sides with axially running drive keys as well as locking recesses on the drive keys and/or axial latch elements which are moved into the locking recesses for axially locking the Kelly bars or moved out of the locking recesses for unlocking. According to the invention provision is made in that by means of a control a locking state of the Kelly bars is checked automatically, wherein by the control the positioning means of the power rotary head and/or the main rope winch are actuated so that the Kelly bars are moved axially relative to each other, in that by means of a detection means a movement distance of the Kelly bars with respect to each other and/or an axial force during movement of the Kelly bars are axially detected, and in that depending on the detected movement distance and/or the detected axial force a locking state of the Kelly bars is ascertained by the control.

The system for making or breaking the riser includes a robotic system. The robotic system includes one or more robotic arms configured to be disposed on a spider deck, and one or more riser-connection manipulation tools each having a camera and being configured to manipulate a riser connection, the camera being configured to capture an image of an object, wherein each robotic arm is configured to couple to one riser-connection manipulation tool. Further the system for making or breaking the riser includes a control system. The control system includes a robot controller in communication with the one or more robotic arms and configured to control the one or more robotic arms. The system for making or breaking the riser is configured to analyze the image to determine the location and orientation of the object and transmit the location and orientation of the object to the robot controller.

Systems and methods for a riser coupling are disclosed. A riser sensor unit for sensing engagement of a riser tool with a riser coupling includes a first sensor attached to a sub of the riser tool. The first sensor is configured to generate a first signal upon detecting contact with the riser coupling, and an intrinsic safety barrier is configured to transmit the first signal to a control system.

An apparatus for detecting over-torquing or un-torquing of a threaded connection between components in a borehole penetrating the earth includes: a string of components coupled in series by a threaded connection; a transmission line attached to each component; a signal coupler in communication with the transmission line and disposed on each component at each threaded connection, the signal coupler being configured to transmit the signal to an adjacent signal coupler on an adjacent coupled component in order to transmit a signal along the transmission line attached to the adjacent coupled component; a receiver configured to receive the signal; and a processor in communication with the receiver and configured to: (i) determine a difference between a characteristic of the signal and the characteristic of a reference signal and (ii) transmit an alert signal signifying that the threaded connection is over-torquing or un-torquing in response to the difference exceeding a threshold value.

Systems and methods for riser monitoring and lifecycle management are disclosed. The riser monitoring and lifecycle management method includes receiving a signal indicative of an identification of a riser component at a monitoring and lifecycle management system (MLMS), wherein the riser component forms part of a riser assembly. The method also includes detecting one or more properties via at least one sensor disposed on the riser component during operation of the riser assembly, and communicating data indicative of the detected properties to the MLMS. The MLMS stores the data indicative of the detected properties with the identification of the riser component in a database.

In systems and methods for detecting steps in connection processes used in well operations using drilling rigs to manipulate tubular strings (such as drill strings and casing strings), sensor data gathered by data acquisition systems (such as electronic data recorders) associated with a drilling rig is analyzed to identify time intervals corresponding to specific steps constituting the complete connection process in question (such as connection make-up or connection break-out). These time intervals are compared against target or benchmark values for the corresponding process steps, thus facilitating identification of “invisible lost time” (ILT), determination of the causes of the ILT, and determination of appropriate measures to mitigate or eliminate the causes of the ILT. These systems and methods eliminate or minimize the need for onsite data collection by human observers using stopwatches or other manual data collection means.

A riser having a riser body having an interior surface, an exterior surface, and two spaced-apart ends, at least one identification assembly on the riser body, the identification assembly having an assembly body and a wave energizable apparatus in the body, the assembly body having an interior surface, an exterior surface, and a channel therethrough in which is positioned part of the riser body, the assembly body releasably secured on the riser body, and the wave energizable apparatus positioned within the assembly body. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).

Systems and methods for preventing improper lifting of tubular members are described, in which sensing devices are used to detect when a tubular reaches a selected position within a lifting device suitable for engagement, and/or to detect when a lifting operation is initiated that would exceed the capacity of a lifting device. Operators are engaged with the tubular member and provided with a preselected force corresponding to the weight of one or more tubular members, such that when the weight of a lifting operation exceeds the preselected force, an audible device may be actuated responsive to sensor output, to immediately alert individuals, such that the improper lifting operation may be halted. Similarly, an audible device may be actuated responsive to sensor output when a tubular member reaches a selected position within the lifting device, such that additional movement may be ceased.

A system and method for mounting a Closed-Mouth Power Tong on a Well Servicing Rig in order is disclosed. The power tong can be operated remotely when making up or breaking out connections on oilfield tubing. The system utilizes an assembly that can lift and lower the tong to the appropriate height as required to engage the threads on the tubing. The assembly is connected to the blowout preventer or wellhead with a quick connect system that is adjustable for various angles so that the tong can be utilized in various positions to run tubing into, or out from, the well center unhindered.
