Gas Lift Series

Gas lift is used to increase flow from producing wells and induce flow from non-inducing wells. These five films teach the concepts behind gas-lift operations using a realistic visual model to demonstrate the principles. The well model and helpful graphical illustrations aid the viewer in understanding the material. These videos are a popular and effective training tool. Produced by Exxon Production Research Company and McMurry Oil Tools. Part of the PETEX-API Audiovisual Repository. 1974.

Part I: Well Model and Lift
This introduction to the Gas Lift Series demonstrates the physical aspects of the model of flowing well and graphical information of pressure versus depth. The video also introduces the principles of pressure gradients, well performance, and well flow meter equipment. Pressure gradients change as well conditions change. 11 minutes.

Part II: The Well—Flowing, Dead, and Unloading
This film looks at three conditions: first, the well flowing; second, the well dying and dead; third, unloading the well. The video demonstrates the conditions under which a well will flow and those under which a well can be induced to flow. It also explains the concepts of drawdown, unloading, and static pressure. 13 minutes.

Part III: The Effect of Gas Rates and Depth of Injection on Well Performance
What happens if gas rates or depth of injection is increased? Does the well production increase as well? This film studies the effects of gas rates and depth of injection on well performance. The video’s study of gas rate effects considers the effects of both formation and injected gas. 12 minutes.

Part IV: The Effect of Surface Conditions on Gas-Lift Performance
When designing a continuous flow gas lift installation for a well, one of the many factors that must be considered is the surface conditions under which the installation must operate. This fourth film of the Gas Lift Series looks at the effects surface conditions have on gas lift performance. Flowing wellhead pressure and input gas pressure and volume are discussed. 11 minutes.

Part V: Valve Spacing and Pressuring
Gas lift valves can aid in the unloading and producing of a well. With the valves correctly spaced and accurately pressured, unloading proceeds in a step by step, valve by valve manner to the optimum point of lift, and maximum liquid production is attained. But if well conditions change, or if the gas lift design data was not very accurate, maximum liquid production is not attained. Improper valve location, improper setting of operating pressures, and gas entry at more than one point can prevent wells from attaining maximum production. 19 minutes.
