Supplementary notes
Figures were calculated by ÌÇÐÄÆƽâ°æ based on absolute figures provided by the source. Figures were rounded.
According to the source, the energy sources are classified as follows:
- Non-conventional oil: oil sands / heavy oil and oil shale
- Non-conventional natural gas: shale gas/tight gas, coal bed methane (CBM), gas hydrates and aquifers
The source distinguishes between "reserves" and "resources" as follows: Reserves: Quantities of energy sources which were accurately recorded and can be commercially extracted using current technologies Resources: Quantities of energy sources which are either proved but currently not commercially recoverable or expected (on the basis of geological indicators) and can be verified by exploration.
