Disclosed is a method for a hydrolytically and hydrothermally stable consolidation or modification of the wetting behavior of porous or particulate geological formations. According to said method, A) a consolidating agent comprising a hydrolysate or precondensate of at least one organosilane and at least one metal compound, the molar ratio between the silicon compounds used and the metal compounds used ranging from 8,000:1 to 8:1, is introduced into the geological formation, and B) the consolidating agent is hardened at an elevated pressure and an elevated temperature. The inventive method is suitable for the hydrolytically and hydrothermally stable consolidation of geological formations, e.g. sand formations of reservoirs that contain a lot of oil or water, as well as for modifying the wetting behavior of geological formations, e.g. in order to simplify cleaning of toxicologically charged industrial soils. |
