Increasing the flow of fluids through a permeable formation
A method is described for treating a fines-containing earthen formation, including both surface and subsurface strata, comprising: (a) injecting into the formation an organosilicon compound selected from the group consisting of organosilane halides, organosilane hydrides, organosilane alkoxides, and organosilane amines. (b) subsequently, injecting steam containing a compound which contains ammoniacal nitrogen selected from the group consisting of ammonium hydroxide, ammonium salts of inorganic acids, ammonium salts of carboxylic acids, quaternary ammonium halides, amine or substituted amine hydrochlorides, derivatives of ammonium cyanate, and water-soluble ammonia or ammonium ion precursors selected from the group consisting of amides of carbamic acid and thiocarbamic acid, derivatives of such amides, tertiary carboxylic acid amides and their substituted and alkylated derivatives.
