It is said that carbon dioxide atmospheric content may triple by the end of the 21st century, should major carbon emissions continue at their current rate – and that is frightening, expensive, and perhaps catastrophic.
With respect to carbon sequestration, a major sink is geologic in nature, and enhanced oil recovery (EOR) happens to sequester significant sums of CO2; along with increased oil production – so needed more than ever. A particularly large sector for crude CO2 usage as a liquid product is the EOR sector, by volume, compared to single volume supply to typical merchant consumers, such as food and beverage customers.
Today, due to pressure from environmental sectors wishing to reduce CO2 greenhouse gas emissions (coupled with a strong need to produce more oil domestically), EOR and more creative means of producing oil and gas in general are very much in fashion. This big push to produce more oil via EOR is a reality, and for the (natural) gas sector, this is evidenced by all the shale formation sources which are now being developed for more gas production, and horizontal drilling.
In terms of natural gas applications for CO2, much of this is called ‘frac’ as an application in natural gas production. This sector has shown huge promise from a volume perspective as well, where single jobs for frac service can range, for example, from two tons to 2,000 tons – above and below these values as well. When the volume is particularly large, significant portable storage or large stationary vessels are brought in to serve these locations with sufficient volume on-site.
