Book excerpt: This manual replaces A Primer of Oilwell Service and Workover and has been totally updated, expanded, and renamed because it has been changed so much. It remains, however, a basic reader of the well servicing industry, and tells the story in a simple, easy-to-understand manner. Profusely illustrated, it covers such items as reservoir drive mechanisms, completion methods, artificial lift, well servicing equipment, fishing, and workover techniques. Anyone who needs a fundamental overview of well servicing, workover, and completion will find this book helpful. An extensive glossary is included.
