Of the total number of wells globally to use artificial lift, 40% employ sucker rod pumps. Pump optimization generally follows established rules of thumb. More advanced pump features, such as pump off ...

Gas lifting is a process of lifting fluids from an oil well by the injection of gas (a) continuously in the upward-rising liquid column (in case of continuous flow gas lift), or (b) underneath an ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

The usual gas lift installation types are classified in two broad categories: tubing flow and casing flow installations. In a tubing flow installation, lift gas is injected in the casing-tubing ...
