Electro-Mechanical Setting Tool (EMST)
Description
The EMST is a unique electro-mechanical down hole setting tool, capable of delivering up to 90,000 lbs of linear force which can be used to set, or un-set, well bore devices in a wide range of tubing and casing sizes. EMST is suitable for use on any conveyance method including slick line, digital slick line, electric line and coiled tubing.
The EMST is governed by an electronic controller that outlines the operational parameters of the tool. Once an initiation command has been acknowledged by this controller then the EMST will activate. Electrical power is supplied from the alkaline battery pack and is routed to a small motor, which provides a high-speed, low torque input into a gearbox. The gearbox takes this high speed, low torque input and generate a low speed, high torque rotational output. This rotational output is coupled to a linear actuator mechanism, which converts the rotational movement to linear movement, and in turn, pulls the slick rod slowly upwards.
- Installation of well bore devices such as:
Bridge-plug, Packers, Valves, Cement retainers and Down hole gauges.
Application
- Less equipment and personnel required.
- Less time required for transport and rigging.
- Quick turn around time.
- Independently powered.
- Non-aggressive setting sequence (Good for older tubing/casing).
- Less environmental hazard.
