Abstract
The chemical stick storage and delivery system includes a chemical stick delivery tube in communication with a well which supports a rotatable chemical stick storage device on the uppermost end of the delivery tube. The delivery tube includes an upper opening and the chemical stick storage device rotates to position chemical sticks sequentially over the delivery tube opening. Within the delivery tube is a first valve positioned directly beneath the delivery tube opening and a second valve spaced below the first valve for a distance sufficient to form a chamber between the first and second valves to receive a chemical stick. A central processor unit controls the operation of the first and second valves so that the first valve is opened while the second valve is closed and the chamber is brought to well head pressure before the second valve is opened to drop the chemical stick from the chamber into the well.
