Artificial Lift Methods: Techniques and Applications

Introduction:

Artificial lift involves using mechanical devices or modifying the hydrostatic column weight to enhance fluid extraction from production wells, primarily for crude oil or water. This course delves into various artificial lift techniques essential for optimizing production rates and return on investment. It covers artificial lift systems in detail, helping participants choose the best methods for economic production. Artificial lift systems are crucial where reservoir pressure is inadequate for natural fluid rise but can also improve flow from naturally flowing wells. Fluids typically include oil, water, or mixtures often loaded with gas.
