Residual Oil Saturation

A reduction in oil saturation occurs as reservoirs are depleted during primary and secondary recovery programs. However even the most effective secondary recovery programs still may not reduce oil saturation to the unrecoverable oil saturation point of the reservoir. In order to continue to reduce residual oil saturation and recover oil at economic rates a program must be put in place that:

  • Increases the mobility of the displacement medium by increasing the viscosity of the water or decreasing the viscosity of the oil
  • Reduces interfacial tension between the oil and water

Leave less oil behind.

EnovaFlood modifies the wettability of the reservoir, reduces interfacial tension and changes the viscosity ratio between oil and water releasing residual oil and increasing proved reserves. EnovaFlood maximizes your ROI with a minimal footprint on your budgets, operations and the environment.
