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.
