Smart Water EOR potential in Brazilian oilfields

When the flooding brine is switched to a Smart Water, the chemical wettability alteration will increase capillary forces and the oil recovery is increased by improving

The imbibition rate, ultimate recovery of the spontaneous imbibition experiments at 90 ◦ C and the modified Amott water index, indicates that Smart Water is more efficient at

Smart Water injection into sandstone reservoir for EOR – Optimal mineral sample preparation and influence of feldspar

To achieve an enhanced oil recovery, certain requirements must be met: Clay must be present in rock, oil has to contain polar components, and initial formation water composition

This study attempts to assess the viability of injecting medium-salinity brines of 25.000 ppm NaCl as a substitute for 1.000 ppm low-salinity Smart Water for injection in

Seawater, which can act as a wettability modifier towards chalk and reservoir limestone at high temperature, is not able to enhance oil recovery from Total and

Hence the Norwegian authorities and the petroleum companies focus some of their efforts on increased and enhanced oil recovery (IOR/EOR) through research and development and
