Abstract
The invention uses two vertical wells and a horizotal well located within the underground formation extending between the two vertical wells. A thermal fluid is injected into the formation through the first vertical well. Hydrocarbons and other fluids are produced from the horizontal well through a first perforated interval located near the first vertical well. After depleting this area of the formation, the first perforated interval is closed off and the process is repeated for successively perforated intervals of the horizontal well, all of which are farther from the first vertical well than the preceding perforated intervals.
