CO2 Sequestration-Enhanced Oil Recovery (CO2/EOR) in the 21st Century

Merchant, D. - Presenter, Merchant Consulting

During the past 47 years, CO2 Flood Technology for Enhanced Oil Recovery Projects utilizing CO2 evolved from a partially understood process filled with uncertainties to a process based on proven technology. This knowledge is currently being used by a limited number of companies that actually know how to design, implement, and manage a CO2 flood for profit. The purpose of this report is to help disseminate this knowledge to operating companies interested in EOR flooding or to CO2 Sequestration Communities interested in storing CO2 in EOR projects.

Carbon Sequestration Options for CO2/EOR from the 20th Century:

In 2015 and 2017, Merchant Consulting published two papers: CMTC-440075-MS “Life beyond 80 – A look at Conventional WAG Recovery beyond 80% HCPV Injection in CO2 Tertiary Floods” and CMTC-502866-MS “Enhanced Oil Recovery – The History of CO2 Conventional WAG Injection techniques developed from Lab in the 1950’s to 2017". The objective of these reports were to target all "10 CO2 Recovery Methods" used to date including “Conventional WAG Techniques” which have been used in over 90% of all the EOR projects conducted to date. Results show Tertiary Oil Recovery can be as high as 26% OOIP with 190% HCPV Injected.

Carbon Sequestration Options for CO2/EOR in the 21st Century:

From 2014 to 2019, the Shale Oil Recovery Revolution killed CO2/EOR Sequestration by driving oil prices down to the $50 dollar range along with the inability to lower CO2 Capture costs from Coal and Gas Powered Power Plants. The purpose of this report is to provide the CO2 Sequestration Community an update of new 21st Century CO2/EOR Technology that will help to compete economically with Shale Oil Technology. These include: Two new CO2/EOR Recovery Methods, new Horizontal Drilling techniques, and inclusion of 45Q Tax Credits to improve overall CO2/EOR Economics.
