The main components of a plunger lift system on an onshore gas well. Subsurface components include a plunger (including a bypass valve), a bottomhole bumper spring, and a standing valve, which prevents fluids from flowing out of the bottom of the tubing.
Plunger lift commonly is used to remove liquids from gas wells or produce relatively low volume, high GOR oil wells. Plunger lift is important and, in its most efficient form, will operate with only the energy from the well.
Plunger lifts are applicable in gas wells that experience liquid loading and have sufficient gas volume and excess shut-in pressure to lift the liquids from the reservoir to the surface. Exhibit 2 lists four common well characteristics that are good indicators of plunger lift applicability.
Plunger Lift is a method of artificial lift that uses the well’s own energy, either pressure or gas rate, to effectively lift fluids to the surface. The plunger creates a seal to the tubing wall to reduce the amount of gas/liquid slippage and lift the fluid to surface as completely as possible.
Introduction to Plunger Lift. Gas Well Deliquification Workshop. Sheraton Denver Hotel Denver, Colorado February 24 - 26, 2014. Introduction to Plunger Lift. David Cosby, P.E. Shale Tec LLC. How does plunger lift work. Why is artificial lift required. When is plunger lift required. Applications and benefits. Installation and operation. Safety.
The two minimum requirements for plunger lift operation are: Minimum gas-liquid ratio ; Well buildup pressure; Plunger lift operation requires available gas to provide the lifting force, in sufficient quantity per barrel of liquid for a given well depth.
As an economical and efficient artificial lift method, plunger lift can be used to unload the accumulated liquids from the bottom of gas wells, which helps lower the bottomhole pressure,...
Plunger lift is an increasingly popular form of artificial lift that energy producers use to help lift oil and gas from their wells. In this video, we explain how plunger lift works using this demonstration model.
plunger lift system is a form of intermittent gas lift that uses gas pressure buildup in the casing-tubing annulus to push a steel plunger, and the column of fluid ahead of it, up the well tubing to the surface.
Plunger lifts are a long term solution. Common plunger lift applications include. Wells with gas-to-liquid ratios of 400 scf/bbl per 1,000 feet of depth. Wells with shut-in pressure that is 1.5 times the sales line pressure. Gas wells with coiled tubing.
