CHAPTER 11 – Gas LIFT
Gas Well Deliquification, 2020Co-Authors: Henry V. Nickens, Mike R. WellsAbstract:Publisher Summary This chapter gives a complete overview of Gas lift. Gas lift is an artificial lift method whereby external Gas is injected into the produced flow stream at some depth in the well bore. The additional Gas augments the formation Gas and reduces the flowing bottom hole pressure, thereby increasing the inflow of produced fluids. For dewatering Gas wells, the volume of injected Gas is designed so that the combined formation and injected Gas will be above the critical rate for the well bore, especially for lower liquid producing Gas wells. For higher liquid rates, much of the design procedure may more closely mirror producing oil well Gas lift techniques. In addition, Gas lift may not lower the flowing pressure as much as an optimized pumping system; there are several advantages of a Gas lift system that often make Gas lift the artificial lift method of choice. For Gas wells in particular, when producing a low amount of liquids, the producing bottom hole pressure with Gas lift may compare well with other methods of dewatering. For higher liquid rates, the achievable producing BHP may be higher than pumping techniques. Of all artificial lift methods, Gas lift most closely resembles natural flow and has long been recognized as one of the most versatile artificial lift methods. Because of its versatility, Gas lift is a good candidate for removing liquids from Gas wells under certain conditions. The two fundamental types of Gas Lifts used in the industry today are continuous flow and intermittent flow, and these are briefly explained in this chapter.

Visualized Experiment of Split-piston Gas Lift
Natural Gas Technology, 2020Co-Authors: Chen Yao-qAbstract:Split piston is a new one which is composed of as phere(obviously less than inner diameter)and a hollow cylinder with a cone at the lower.A Gas lift which is composed of thisu nconventional piston was successfully applied to America Texasa nd an obvious stimulation effect was obtained.In this paper,av isualized experimental facility of split-piston Gas lift,with 18 mh igh and a diameter of 40mm,is developed based on principle of continuous Gas lift.It is featured by reasonable basic structure andw orking principle.The main auxiliary parts of both upstream ballc ylinder trigger and downstream buffer can be optimally designedb y experiments;and a physical model of split-piston continuousg as lift is also systematically experimented;meanwhile,liftc haracteristics are tested;compared with some conventionalc ontinuous Gas Lifts,its efficiency can be increased evidently.

Gas Lifts mediterranean operator spirits
Offshore engineer, 2009Co-Authors: Roger Knight, Julian CallananAbstract:For the Mediterranean, where Gas production expenditure over the last five years has dwarfed oil production expenditure, many of the dire, oil-price focused prognoses and generalisations made at global level are now becoming questionable. Infield Systems' Dr Roger Knight (left) and Julian Callanan (right) appraise the immediate developments around the Mediterranean and identify future areas of opportunity.
