Low Salinity EOR in Sandstone Reservoirs by Angy Carolina Taborda Velasquez is a document available to read on EtoBox.
This paper studies the effects of low salinity water composition versus salinity on enhanced oil recovery in sandstone reservoirs. Laboratory experiments show that improved oil recovery can be achieved using higher salinity brines than the typical threshold of 5000 ppm, including brines of 25,000 ppm NaCl and 40,000 ppm NaCl. The speed and amount of oil production is influenced by both the concentration of Ca2+ ions in the formation water and the overall salinity of the smart water brine. While lower salini
