ABSTRACT:
A method of flooding a petroleum reservoir by way of an injection well to aid in the recovery of hydrocarbons from a recovery well includes running a radioactive well logging tool in the injection well to derive a first well log of the reservoir in the vicinity of the injection well. The reservoir is then flooded with a solvent injected into the reservoir at a predetermined rate from the injection well. The radioactive well logging tool is again operated to derive a second well log. High salinity salt water is injected into the reservoir from the injection well. The radioactive well logging tool is run again to derive a third well log. The well logs are utilized to provide a record of the effectiveness of the solvent flood.
