Problems solved by technology

After some period of production, the natural pressure of the oil reservoir decreases and production dwindles.
One difficulty with the use of nitrogen and optionally CO2 to increase oil production is that it requires large quantities of both gases, and the availability of such large quantities is limited.
Nitrogen is generally available from air separation processes, but it is not considered economical to utilize air separation processes solely for the generation of nitrogen for EOR.
CO2 from natural sources can be utilized, but generally requires the natural source to be in the proximity of the oil reservoir to avoid the construction and use of pipelines, which could make such use uneconomical.
Use of CO2 from combustion sources (such as power plants) has also been considered (see, for example,

Abstract

The present invention relates to an enhanced oil recovery process that is integrated with a synthesis gas generation process, such as gasification or reforming, and an air separation process for generating (i) an oxygen stream for use, for example, in the syngas process or a combustion process, and (ii) a nitrogen stream for EOR use.
