Feasibility of an EOR MicroPilot for Low-Salinity Water Flooding

Over the past decade low-salinity water flooding has emerged as a viable enhanced oil recovery (EOR) method. Both<br>laboratory tests and field trials have shown that injecting chemically modified water instead of seawater can lead to<br>incremental oil recoveries. Although much research has been conducted, the governing physical and chemical mechanisms for<br>this increase in recovery are not yet agreed upon, but are generally believed to involve some form of interaction between the<br>rock, oil, and brine leading to changes in wettability, oil/water interfacial tension, or both.
