Well Service and Workover Series Lesson 8
This training manual concerns cleanout and repair methods to recondition oil and gas wells so they can be put back on production. About twenty thousand new wells are completed every year in the United States thus to replace some of the oil and gas production lost by normal decline. Much the same effort is required to keep in good condition the half million or so producers already completed. Workover and repair of old wells is an important part of the oil business. Topics include completion and workover fluids, sand cleanout, sand control measures, plug backs, squeeze cementing, casing repairs, sidetrack drilling, and drilling deeper. Readable language, clearly labeled illustrations and photographs, and helpful self-test review questions help the reader understand the material. ISBN 0-88698-064-X. 1971, 32 pp.
