Well Completion and Servicing
This book provides technical information on well completion, from drilling in the pay zone to production start-up. It also covers the main methods for artificial lift, and well servicing. The reader will find a discussion of the concepts and equipment that are indispensable for scheduling and designing completion and servicing operations. The book's chief objective is to provide comprehensive information to those who require a thorough understanding of the completion engineer's aims and the resources he needs for oil field development and production. It is particularly well-suited to the needs of the specialist whose field of activity is located upstream from oil and gas production, e.g., geologists, geophysicists, and reservoir, drilling or production facility engineers. It should also be of use to oil company administrative personnel, including those in management, and those in the insurance and legal departments. The text is fully illustrated, thus helping the reader grasp the basics of this highly technical field.Contents: 1. Introduction to completion. 1.1. Main factors influencing completion design. 1.2.
