Downhole logging of gas storage field wells to determine cathodic protection (c.p.) levels is expensive and requires removal of the well from service. A technique allowing the prediction of downhole c.p. levels by modeling combined with limited field measurements would provide the industry with a cost effective means of implementing and monitoring casing protection. The results of a research program sponsored by the Pipeline Research Committee of the American Gas Association (A.G.A.) to develop a predictive computer model are discussed in this paper.
