	Gas lift - Wikipedia, the free encyclopedia
		Gas lift is one of a number of processes used to artificially lift oil or water from wells where there is insufficient reservoir pressure to produce the well.
		Gas may be injected continuously or intermittently, depending on the producing characteristics of the well and the arrangement of the gas-lift equipment.
		Gas lift is a form of artificial lift where gas bubbles lift the oil from the well.

	CEALC Products -- Gas Lift Optimization and Design Program (GLOP)
		The Gas Lift Optimization and Design Program (GLOP), is one of the most comprehensive programs for the simulation and design of a gas lifted well.
		GLOP is used by almost all gas lift vendors worldwide and major oil companies to design gas lift for individual wells.
		The lift gas supply operating pressure, temperature and allocated injection rate are important factors in the analysis.

	Petroleum - Wikipedia, the free encyclopedia
		According to this theory, oil is formed from the preserved remains of prehistoric zooplankton and algae which have been settled to the sea bottom in large quantities under anoxic conditions.
		The reactions that produce oil and natural gas are often modeled as first order breakdown reactions, where kerogen is broken down to oil and natural gas by a set of parallel reactions, and oil eventually breaks down to natural gas by another set of reactions.
		In this type of cogeneration plant, a gas turbine is used to generate electricity and the waste heat is used to produce steam, which is then injected into the reservoir.

	Stabilus lift-o-mat, lift o mat, LiftOMat, stabilus lift-o-mat gas springs
		The Stabilus lift-o-mat gas spring can be designed with an approximately linear, progressive or digressive spring rate curve, to match a particular need.
		The characteristic curve of the gas spring describes the progression of the force of the gas spring over the stroke, from the extended to the compressed state and vice versa.
		If the gas spring rate is flat and progresses in a practically linear manner, the force of the gas spring consequently rises only slightly over the entire spring travel.

	Gas spring dampers, horizontal use & gas prop & lift technical information
		All gas springs contain a small amount of oil to lubricate the main seal and rod and provide end of stroke damping (see damping).
		If standard gas springs are operated and mounted in a rod up orientation, fluid cannot reach the main seal or rod which leads to excessive seal wear and reduced life.
		It is recommended that standard gas springs be mounted rod down at least 30 degrees off horizontal.

	Gas Lift Manual
		Gas lifting can be used throughout the whole lifespan of an oil well: from the time it dies until its abandonment.

	Echometer -- Papers: Acoustic Determination of Bottomhole Pressures in Gas Lift Wells
		Producing and static bottomhole pressures in gas lift wells are useful in designing and operating gas lift installations.
		The flow characteristics given by the static and producing bottomhole pressures are useful in selecting the depths for additional valves, determining gas injection rates, and optimizing the gas injection system.
		Gas lift efficiency can be determined and the flow rate at any producing bottom hole pressure can be determined by using an inflow performance curve.

	Oilfield Glossary: Term 'gas lift'
		An artificial-lift method in which gas is injected into the production tubing to reduce the hydrostatic pressure of the fluid column.
		The injection gas is typically conveyed down the tubing-casing annulus and enters the production train through a series of gas-lift valves.
		The gas-lift valve position, operating pressures and gas injection rate are determined by specific well conditions.

		In wells where the natural reservoir energy will not create sufficient differential pressure to drive production fluids to surface, artificial lift systems such as gas lift are used to supplement the natural energy enabling the well to produce.
		Gas lift valves are installed in side-pocket mandrels and spaced out along the production string.
		It may also be used to isolate the perforations and protecting the formation from any damage due to kill fluid loss, or used for landing a choke for regulating the production flow rate.

		The time frame from initial production to the need for secondary or enhanced recovery is governed only by the initial size and pressure of the producing reservoir.
		After all of these are exhausted there still remains, in all but very dry reservoirs, a large amount of gas left in place.
		Because liquids are no longer lifted to the surface they build up in the production tubing and the reservoir pressure is overcome by hydrostatic head causing the operation to be suspended.
