Gas-lift is one of the predominant forms of artificial lift used for lifting liquids from conventional, unconventional, onshore and offshore assets. Gas-lift and its various forms (intermittent lift, gas-assisted plunger lift) allows life of well lift-possibilities when selected and applied properly. Rajan Chokshi offering this 3-days course to give insight on gas lift optimization and demonstrate the advantages and limitations of gas-lift systems.
Most all oil and gas wells require artificial lift at some point and for most of the life cycle to achieve production objectives. There are at least eight forms of artificial lift technologies available in the market. Each lift system’s applicability often overlaps with other lift system(s) and it is important to understand positioning and strength of a particular lift form. Unlike mechanical forms of lift methods, gas-lift performance relies heavily on understanding interdependency between reservoir, wellbore and surface installations. This course is designed to give trainees thorough understanding of gas-lift technology and related application concepts in unconventional and tight oil and gas wells. Related production optimization topics are also discussed.
