Corrosion Problems in Water Flooding

Abstract The seven basic methods of detecting corrosion in water flood operations are water analyses, corrosion coupon tests, corrosion probe tests, bacteria tests, corrosion probe tests, bacteria tests, membrane filter analyses, review of the corrosion history, and examination of existing equipment. Each of these methods is discussed briefly. Consideration is given to some of the principal causes of internal corrosion. Methods of controlling such corrosion include inhibitor treatment, aeration, bacteria control, cathodic protection and the use of corrosion resistant materials. External corrosion problems are discussed briefly with particular attention being paid to buried surface lines and well casing. 4.6.12
