DESCRIPTION

The course begins with a quick overview of production systems analysis and justification of gas lift as a means of increasing well productivity, followed by an introduction to gas lift principles, surface installations, and downhole equipment. The three basic elements of continuous gas lift design are covered thoroughly: operating valve positioning, unloading valve positioning, and valve sizing. Other topics covered in the course include gas lift operations, multi well lift gas allocation, and optimization, as well as a special section devoted entirely to intermittent gas lift.
