    Oil sands are a mixture of sand, water, heavy oil and other minerals; heavy oil is often classified as bitumen [U .S . EIA,2016c]. These deposits cannot be tapped with standard production methods (e.g., natural flow into production wells) [Rogner,1997] and therefore require more complex and advanced technologies [Chew,2014].
