IN SITU RECOVERY FROM A HYDROCARBON CONTAINING FORMATION

摘要

A hydrocarbon containing formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion (805) of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion (805) at a selected rate during pyrolysis of hydrocarbons within the formation. A mixture (807) of hydrocarbons, H2, and/or other formation fluids may be produced from the formation. The mixture (807) may be separated into condensable hydrocarbons (815) and non-condensable hydrocarbons (813) . The condensable hydrocarbons (815) removed from the formation may be a high quality oil that has a relatively low olefin content and a relatively high API gravity.
