A B S T R A C T METHOD OF RECOVERING HYDROCARBONS FROM AN UNDERGROUND FORMATION To prevent dissolution of sand grains or of the original bond between these grains around a well when hot aqueous fluid is passed through the well in an oil recovery process, the sand grains are at least once treated with a solution of Al ions in a solvent such as water. Such treatment with Al ions of sand grains is also beneficial when the grains have been consol- idated by means of a silicon polyhalide. Attack of the bond between the grains by formation water is then considerably decreased.
