Abstract:
A crude oil recovery chemical fluid is described and claimed. This fluid has been shown to exhibit excellent resistance to salt and high temperatures. This crude oil recovery chemical fluid includes a silane compound, an aqueous silica sol having an average particle diameter of from about 3 nm to about 200 nm, two or more anionic surfactants, and one or more nonionic surfactants.

Claim (Index 12):
A process for recovering crude oil from subsurface hydrocarbon comprising layer, comprising the steps of:\n (a) pressing a crude oil recovery chemical fluid comprising a silane compound, an aqueous silica sol having an average particle diameter of from about 3 nm to about 200 nm, two or more anionic surfactants, and one or more nonionic surfactants into subsurface layer; and (b) recovering crude oil from a production well together with the chemical fluid which was pressed into the subsurface layer.
