Enhanced oil and gas recovery (EOR/EGR)
Efficient use of oil and natural gas fields requires large amounts of nitrogen or carbon Dioxide. Even if global natural gas reserves will last longer than oil reserves, all of these sources must be used in the best possible manner. Nitrogen is an important tool for this. It is injected into reservoirs that lie deep under the surface of the earth in order to increase the pressure in these reservoirs, which drops as the extraction period continues. Linde engineers are developing system modules that can be used to increase the recovery quota of fossil fuels in an environmentally sound manner.
