About the book
The continuous global increase in oil demand and the decrease in discovering new petroleum reservoirs have derived the need to recover more oil from mature fields before they were abandoned. Enormous amounts of oil remain unrecovered after primary and secondary recoveries due to poor displacement and sweep efficiencies. Much of this oil can be efficiently and economically extracted by enhanced oil recovery techniques. Increasing oil recovery from mature fields can be achieved by improving the sweep efficiency and the mobilization of oil through the porous formation. This book intends to present various techniques employed in enhanced oil recovery (EOR). The methods to be discussed can include CO2 and miscible gas injection, polymer flooding, alkaline flooding, surfactant flooding, microbial EOR, and thermal methods. State-of-the-art modeling and experimental results from research and field projects are also welcome in this book, as well as the EOR economic strategises, given that the viability of any EOR project is strongly correlated with the injection fluid costs and crude oil prices.
