Method to determine drift and residual oil saturation |
摘要 |
Drift or residual oil saturation within a reservoir around a wellbore is determined by injection of a water-soluble tracer and then producing from the well. This injection is performed twice. The first injection is immediately followed by production in order to create a baseline. The second injection is followed by a soak period, and then production. Production of the tracers is compared to determine drift or residual oil saturation within the reservoir.
