| Popis: |
Carbonate coreflood experiments have demonstrated the potential for Advanced Ion Management (AIMSM) to significantly increase oil recovery compared to waterflood using formation water. AIMSM involves adding and/or removing ions from the injection water to improve waterflood performance. AIMSM further improves current state-of-the-art processes through the addition of certain salts and/or the softening of water. Simulations have accurately matched the experiments, providing a tool to assess field-scale recovery and supporting the premise that the increased recovery is due to a change in wettability. This study shows that a relatively inexpensive and straightforward modification of injection water composition can significantly increase oil recovery. |
