Abstract Waterflooding has been practiced as a secondary recovery mechanism for many years with no regard to the composition of injected brine. However, in last decade, there an interest understand impact water and low salinity waterflooding (LSWF) oil recovery. LSWF investigated through various laboratory tests promising method improving carbonate reservoirs. These experiments showed diverse m...

Abstract Higher oil recovery after waterflood in carbonate reservoirs is attributed to increasing water wettability of the rock that turn relies on complicated surface chemistry. In addition, calcite mineral reacts with aqueous solutions and can alter substantially composition injected by dissolution. Carefully designed chemical and/or brine flood compositions laboratory may not remain intact w...
