Low-Energy Processes for Unconventional Oil Recovery fills a gap in oil and gas literature. Today, in our globalized society, the oil industry has to demonstrate how oil recovery can be done responsibly over the life-cycle of the project, clearly articulating energy efficiency as well as limiting CO2 and environmental footprints of the chosen recovery processes. The authors bring together their complementing expertise to provide the reader with an in-depth discussion of a range of alternative recovery techniques. Most recovery methods included are focused on heavy oil recovery, but some have applications in light oil reservoirs as well. With the recent industry drive and focus to recover hydrocarbons from tight rock and shale resources, a chapter has also been devoted to shale oil recovery.
