2. Definitions (1) conventional natural gas –free natural gas –oil associated gas non-conventional natural gas –tight gas –coal bed methane (CBM) –aquifer gas –gas hydrates 2nd ASPO workshop, Paris, May 26/27

3. Definitions (2) reserves hydrocarbon quantities proven in fields which can be produced economically with current technologies resources - geologically identified hydrocarbons which can’t be economically produced under present conditions - unidentified but expected hydrocarbons due to geological reasons in equivalent regions (yet to find) Hereby we consider for reserves as well as for resources the recoverable amount 2nd ASPO workshop, Paris, May 26/27
