  • Well string injection system and method
    Patent number: 7383879
    Abstract: A continuous feed injection unit used for example for injection and removal of continuous well string from wells operates in a dual speed configuration. The unit comprises a first hydraulic motor, a second hydraulic motor, cooperating continuous well string gripping chains connected to be driven by the first and second hydraulic motors, a hydraulic power supply connected to provide pressurized fluid to the first and second hydraulic motors and a control system for the hydraulic power supply. The control system for the hydraulic power supply has a motor speed control valve with at least a first and second operating configuration, the first operating configuration providing power fluid to the first and second hydraulic motors in parallel and the second operating configuration providing power fluid to the first and second hydraulic motors in series. The hydraulic power supply may be a conventional power tong hydraulic supply.

  • Guide support for rig mounted continuous feed injection unit
    Patent number: 6880630
    Abstract: A continuous well string injection system, comprising a rig, such as a drilling or service rig, a continuous feed injection unit suspended from the rig, a continuous well string guide forming a conduit for continuous well string between a continuous well string holder and the continuous feed injection unit, the continuous well string guide being suspended from the rig at a suspension point between the continuous feed injection unit and the continuous well string holder; and a tension device, such as a cable, straddling the suspension point to restrain lateral movement of the continuous well string injection unit in relation to the continuous well string holder.
