FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to the oil industry. Process for altering wettability properties of a carbonate formation to stimulate oil production includes selecting an oil bearing carbonate formation; injecting a silicide dispersion into the carbonate formation; reacting the injected silicide dispersion with in the carbonate formation in order to remineralise the surface of the carbonate formation based on the calcium-silicon phase or a calcium-silicon adduct in order to alter the wettability properties of the carbonate formation towards improving wettability with water.
EFFECT: technical result is an improvement in the wettability of the carbonate formation with water and the resulting increase in the mobility of oil and its production.
