Plunger Lift Systems Plunger Lift Technology is a cost effective and efficient technique that optimizes oil and gas production in wells which have nominal flow trends. As slugs of fluid travel to the surface, as much as 75% of the fluid may fall back and continue to accumulate downhole. More accumulation equals slower production. The accumulation of fluid is known as “liquid loading” and can be detrimental to well production. Without assistance, the column of fluid will grow too heavy to pass through and the well stops producing. A Plunger Lift System is an ideal solution for these well conditions. It uses an interface seal between the accumulated fluid and the stored gas in the annulus. The well is shut-in to allow the plunger to travel to the bottom which creates a bottomhole seal and well pressure to build. After a period of shut-in time, the head gas is blown down creating differential pressure across the plunger which brings the plunger to surface. As the plunger travels up the tubing, it lifts the fluid column to the surface and a turbulent seal is formed which practically eliminates liquid fall back. The fluid column is lifted up and out allowing the well to produce again. The system is comprised of a well specific plunger, a bottom hole bumper spring, a specialized lubricator and catcher assembly, an electronic controller, motor valve and an arrival sensor. With the Plunger Lift System advanced controls and wide variety of optimization solutions, NOV Monoflo is able to offer a cost effective solution and environmentally friendly method of artificial lift. The NOV Monoflo Plunger Lift System is the most economical and environmentally friendly form of artificial lift technology on the market today. Applications The NOV Monoflo Plunger Lift System is the ideal solution for a wide range of applications and conditions including: • Dewatering liquid loading gas wells • Wells with high gas-to-oil ratio • Wells that are currently being soaped • Paraffin and hydrate control www.nov.com/ArtificialLift MonofloALS@nov.com
