PRODUCING HYDROCARBONS FROM SUBTERRANEAN RESERVOIR WITH SOLVENT INJECTION AT CONTROLLED SOLVENT DENSITY

PRODUCING HYDROCARBONS FROM SUBTERRANEAN RESERVOIR WITH SOLVENT INJECTION AT CONTROLLED SOLVENT DENSITY

In a hydrocarbon recovery process, a solvent is injected into the reservoir at an injection pressure and an injection temperature selected and matched such that, the solvent has a reduced density of less than 0.5 and a second derivative of the reduced density with respect to temperature is less than...

Zusammenfassung:In a hydrocarbon recovery process, a solvent is injected into the reservoir at an injection pressure and an injection temperature selected and matched such that, the solvent has a reduced density of less than 0.5 and a second derivative of the reduced density with respect to temperature is less than 1, at the injection pressure and the injection temperature.
