A stick launcher (10) and method for launching soap sticks into a gas or oil well. The stick launcher comprises a containment vessel (20) adapted to house the soap sticks (35), the containment vessel (20) comprising a contiguous wall (22) and a top (24) and a bottom (26). A turret-style separator (40) is positioned within the containment vessel (20), the separator (40) comprising blades (42), and adapted to contain the soap sticks (35) between the blades (42) of the separator (40) and the contiguous wall (22) of the containment vessel (20). A valve (50) is positioned adjacent the bottom (26) of the containment vessel (20), the valve (50), when in open position, is adapted to be in fluid communication with a wellbore (150) and the containment vessel (20). A rotating assembly (60), when set in motion by an actuator (80), is used to rotate the separator (40) and simultaneously open or close the valve (50). The rotating assembly (6) comprises a ratchet mechanism (62) and an actuator plate (82) that, while acting on the separator (40) to advance a soap stick (35) into position in the passage way (31), opens and closes the valve (50) so that the containment vessel (20) and soap sticks (35) have minimal contact with the moisture laden fluids of the wellbore (150). |
