Abstract
In this study, we propose to quantify the control of mineral composition and water chemistry on water/rock interactions by
using oil during low salinity water flooding of spatially heterogeneous sandstone porous media. A sandstone core and free clay sand
core were prepared in chromatography columns and were water flooded sequentially with high low salinity water at the reservoir
temperature of 90°C. Brine with high salinity (100,000) ppm was injected to simulate formation water. Then, Inflow LS water (1100)
ppm. One of the columns only contains quartz; to investigate the role of the clay in the mechanism of LS water enhanced oil recovery
(EOR). The other column contained quartz and identical quantities of clays. The results showed that during flooding, the free clay
column with LS water the oil recovery from the quartz column was as great as that of the clay containing cores. The pH also increased
significantly during LS water flooding for the free clay column.
