 This paper provides a comprehensive review of enhanced oil recovery, EOR, technologies and their potential to increase final recovery factors in various types of reservoirs, with a focus on sandstone and carbonate formations in turbiditic reservoirs, offshore and onshore fields, and emerging trends such as CO2 injection, high-pressure air injection, HPAI, and chemical flooding. The paper also discusses the risk and rewards associated with these methods and provides an overview of CO2 EOR project economics.
