  • Publication number: 20060213654
    Abstract: A safety valve system for removing down-hole tools from a coal-bed methane well. The system includes first and second horizontally opposed stuffer-blocks, a stuffer-box housing for housing the stuffer-blocks, a means for attaching said stuffer-box housing to a coal-bed methane wellhead, and a means for delivering fluid to move the stuffer-blocks between an open position and a closed position. In one embodiment, the safety valve system further includes a controller, at least one methane sensor, a stuffer-box position sensor, and a stuffer-block activation system. A control algorithm is stored on or in communication with the controller enabling the controller to control the position of the stuffer-blocks, moving the stuffer-blocks between an open and closed configuration, wherein the stuffer-blocks are maintained in an open configuration if the methane level is below a predetermined threshold level. The valve system may further comprise a free-rotating stripper-diverter atop of the valve system.
