Abstract: The chemical stick with soluble stabilizer eliminates or greatly reduces the problem of fractured chemical treatment sticks in wells, where such sticks occasionally break into relatively short lengths and jam crosswise within the well pipe. The chemical stick includes one or more water soluble stabilizer elements that extend substantially the length of the stick, and which add to the physical strength of the stick to greatly reduce breakage. The stabilizer or reinforcement element(s) are also sufficiently flexible to avoid fracturing if the remainder of the body of the stick is cracked or fractured. The reinforcement element(s) maintain the integrity of the stick, and prevent its separation into separate fragments. Polyvinyl alcohol (PVA) is a suitable stick stabilizer, as polyvinyl alcohol is water soluble in order to dissolve in the well and does not adversely affect the detergent or surfactant in the well treatment stick.

Abstract: The automated chemical stick loader includes a ground-based stick storage and dispensing cabinet, an automated valve actuating system atop the wellhead, and a fixed stick transfer tube extending between the storage and dispensing cabinet and the top of the wellhead. A series of chemical sticks are stored in an endless conveyor in the cabinet, with the cabinet dispensing the sticks singly and sequentially to the bottom of the transfer tube upon actuation of the system. Sticks are pushed linearly up the transfer tube until reaching the top of the wellhead, whereupon the topmost stick falls into the well when the valves are actuated to allow passage of the stick therethrough.

Abstract: An automatic chemical stick loader apparatus for gas wells, including a storage and dispensing cabinet at ground level, for sequentially feeding sticks therefrom, a launch tube for sequentially receiving sticks and elevating them to the top of a well head, and a stick loader atop the well for receiving a stick from the launch tube, dropping the stick into a chamber, pressure isolating the chamber and pressure equalizing it with well pressure, and dropping the stick into the well. The apparatus is controlled by an electronic controller which may be solar powered. The apparatus is operated by well gas, the pressure thereof being regulated down to 20 psi or so.
