VENTURI GAS LIFT VALVE: THEORY AND PRACTICE

The Venturi valve represents a significant advance in the technology of artificial lift by gas lift. Understanding theoretical and practical aspects related to the use of the valve is fundamental to maximize the benefits of its application. This review article presents the concepts involved in that innovation, discusses advantages and limitations of that technology, provides means to perform gas flow rate calculations, and describes practical aspects that must be observed for a good performance of the valve.
