Abstract
Subterranean formations are treated with acid, by a method comprising the steps of: (1) forming an acidizing composition by mixing an aqueous acid component with at least one water-soluble organosilicon compound; and (2) injecting the composition into the formation. Suitable organosilicon compounds include water-soluble organosilanes and organosilanes which hydrolyze to form water-soluble silanols. By using the organosilicon compound, movement of formation fine particles is inhibited and swelling of clays by aqueous fluids is reduced, thus tending to maintain formation permeability.
