“In situ” visualization of phase states and transformations of hydrocarbons in water-oil mixtures at high and ultrahigh temperatures and pressures

In this work, we report the results of these studies recently obtained for fluid inclusions in synthetic quartz. The latter was grown using a previously described technique [1, 2] simultaneously with the occurrence of interaction of weakly alkaline chloride bicarbonatesodium (10 and 20 wt % NaCl + 7 and 10 wt % NaHCO3) and alkaline carbonatesodium(5.0 and 7.0 wt % Na2O3) solutions with oil of the Western Belyakovskoe deposit (North Caucasus)
