Abstract
Method and apparatus of inhibiting corrosion of well tubing. A corrosion monitor detects the concentration of a corrosive element in fluid produced from well tubing. Corrosion inhibitor is injected into the tubing by a pump at the depth at which water vapor condenses. A computer is programmed with a formula which generates an optimum concentration of corrosion inhibitor for a given concentration of the corrosive element. The computer is operatively connected to the monitor and receives data therefrom to generate a signal which is used to control the pump speed.
