The document discusses various types of well completions, including: 1. Open hole, slotted liner, gravel pack, cemented and perforated liner, and horizontal well completions for vertical or deviated wells. 2. Natural flow and artificial lift completions, as well as single and multiple zone completions. 3. Specific completion methods are described for horizontal wells including open hole, slotted liner, gravel pack, external casing packer, and cemented and perforated liner completions. 4. Artificial lift completions including rod pumps, hydraulic pumps, gas lift, and electrical submersible pumps are also summarized.
