This reduces the oil's viscosity and causes the oil to  The CO2 from a natural or industrial source is injected into a selected oil reservoir either as continuous gas or as water-alternating-gas injection also known as 

The enhanced oil recovery process can be achieved by many techniques like; ( gas injection, chemical injection, ultrasonic stimulation, microbial injection or 

As such, the reservoir pressure is main- tained while allowing the production of oil and associated gas to continue. Pressure maintenance. Nitrogen is injected into  28 Sep 2015 Gas methods involve the injection of gas (natural gas, nitrogen or CO2) to improve the oil sweep. Depending on the interaction between injected  This includes Enhanced Oil Recovery (EOR), Enhanced Gas Recovery (EGR) Secondary production usually consists of injecting water into an oil reservoir to  Overview of Gas Enhanced Oil Recovery. Injection of gas accomplishes three things: More gas dissolves in the oil and reduces its viscosity; The gas that  Our range of enhanced oil recovery project expertise includes: Polymer Flood Facilities; Water Flood Facilities; Gas Injection; CO2 Flood Facilities including 

The most common secondary recovery techniques are gas injection and waterflooding. Normally, gas is injected into the 

Gas is usually injected into the gas cap of the formation instead of directly into the production zone like water injection. 3.3 Tertiary Recovery. Tertiary recovery includes methods of petroleum production that are used to increase the mobility of the oil in order to increase extraction. Enhanced Oil Recovery (EOR) (also called Tertiary Recovery, as opposed to Primary Recovery and Secondary Recovery) is a technique for increasing the amount of hydrocarbon that can be extracted from a reservoir using thermal, chemical, miscible gas injection, or other methods.Sometimes the term quaternary recovery is used to refer to more advanced, speculative, EOR techniques. Gas Injection. In gas injection EOR, Nitrogen, CO 2, or natural gas is injected into the reservoir to improve or stabilize production. Gas flooding improves natural gas recovery by expansion and crude recovery by dissolving in the oil to decrease its viscosity and improve flow. Secondary Oil Recovery. This method involves the injection of gas or water, which will displace the oil, force it to move from its resting place and bring it to the surface. This is typically successful in targeting an additional 30% of the oil’s reserves, though the figure could be more or less depending on the oil and of the rock This is the landing page for links to EOR related topics -- Immiscible gas injection in oil reservoirs, Conformance improvement, Polymer_waterflooding, Miscible flooding, Thermal recovery by steam injection, and In-situ combustion. injection, natural gas miscible injection, and steam recovery in a tertiary or enhanced oil recovery (EOR) phase [1]. Primary recovery: Glover (2001) explained all recovery methods, including primary recovery mechanism as it is the stage when the natural energy of the reservoir is used to

Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, there are three primary techniques for EOR: thermal, gas injection, and
