In-situ reduction of oil viscosity during steam injection process in EOR |
摘要 |
A method for lowering the viscosity of a heavy hydrocarbon in situ in a well formation so as to improve well production wherein the heavy hydrocarbon has an API gravity in the range between 6 DEG and 12 DEG and a dynamic viscosity in the range between 300 and 900 centipoises @ 195 DEG F. comprising lowering the viscosity of a virgin heavy hydrocarbon outside of a well formation wherein said heavy hydrocarbon has an API gravity in the range between 6 and 12 degrees and a dynamic viscosity above 300 centipoises @ 195 DEG F. so as to make pumpable with conventional pumping equipment comprising mixing said hyrdocarbon at a temperature range between 400 DEG and 500 DEG F with steam and an additive selected.
