Abstract: 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.

Abstract: A walking system for a workover rig or completion rig mounted on a motor vehicle. The walking system includes a main platform having ramps and tracks for the motor vehicle to drive up onto and a base beam extending perpendicularly on both sides of the main platform to act as outriggers for stability. The system further includes a workstring platform for storing tubulars that make up the workstring, which is elevated above a wellhead. The main platform and base beam have walking assemblies for lifting the rig and moving it laterally so that it can be positioned over the wellhead for workover or completion operations.

Abstract: 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.

Abstract: A passive rotating jointed tubular continuous snubbing injector is provided 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 injector can include variable diameter gripping mechanisms that, in combination with linear drive mechanisms, can apply radial force onto and over a certain length of the tubular, of the tubular string, and onto and over a coupling or tool joint connecting tubulars together while moving the tubular string axially into or out of the well. Further, the injector may rotate in response to the rotation of tubulars while the injector is moving the tubular string into or out of the well.
