Abstract
A method for enhancing oil recovery (EOR) from a limestone or dolomite formation containing crude oil and connate water comprises: -determining a SO42-/Ca2-ratio (Mo1/Mo1) in the connate water; and -injecting into the formation pore spaces an aqueous displacement fluid with a SO42-/ Ca2+molar ratio (Mo1/Mo1) above 1 and a higher SO42-/ Ca2+molar ratio (Mo1/Mo1) than the connate water. The method modifies the wettability of the limestone or dolomite formation such that its oil wettability is reduced and its water wettability is increased. Figure 17 shows that only brines LS2 and LS3 will be effective in wettability modification. In Table 5 it is shown that these brines have a SO42-/ Ca2+ratio (Mo1/Mo1) above 1 and a higher SO42-/ Ca2+ratio (Mo1/Mo1) than the connate water.
