The report card for unconventional oil and gas producers from a leading industry analyst is A+ for growth and F- for paying back investors. An operator has designed a demonstration project for carbon dioxide (CO2) enhanced oil recovery (EOR) and has implemented it in one of its fields. This paper presents an overview of the SACROC Unit’s activity focusing on different carbon dioxide (CO2) injection and water-alternating-gas (WAG) projects that have made the SACROC unit one of the most successful CO2 injection projects in the world. A new material under development is highly effective at sieving carbon dioxide from natural gas streams and is also cheap and easy to make, according to researchers. This study explores the mechanisms contributing to oil recovery with numerical modeling of experimental work and investigates the effects of various parameters on oil recovery.
