SPE 118830 Efficient Simulation for Low-Salinity Waterflooding in Porous and Fractured Reservoirs
Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...
متن کاملTitle : “ Evaluation of the Impact of Reservoir Heterogeneity and Mixing on Low Salinity Waterflooding ” Speaker :
The impact of heterogeneity induced mixing between the injected low salinity water and the high salinity connate water is investigated in secondary low salinity waterflooding (LSW). Although LSW has proved to be a promising EOR process in laboratory experiments and field trials, its efficiency can be altered due to mixing with in situ higher salinity connate water. This mixing is caused by mole...
متن کاملThin liquid films in improved oil recovery from low-salinity brine
a r t i c l e i n f o Keywords: Low-salinity Waterflood LSW Brine Double-layer Sandstone Carbonate Film Low-salinity waterflooding is a relatively new method for improved oil recovery that has generated much interest. It is generally believed that low-salinity brine alters the wettability of oil reservoir rocks towards a wetting state that is optimal for recovery. The mechanism(s) by which the ...

متن کاملMechanisms of salinity tolerance.
The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, organ, and whole-plant level. Plant growth responds to salinity in two phases: a rapid, osmotic phase that inhibits growth of young leaves, and a slower, ionic phase that accelerates senescence of mature leaves. Plant adaptations to salinity are of three disti...
