Davis, B W

This patent describes an improvement in a method for recovering oil from an underground oi-bearing earth formation penetrated by an injection well and a producing well, in which method carbon dioxide is injected into the formation to displace oil towards the producing well from which the oil is produced to the surface. The improvement comprising injecting into the formation carbon dioxide. The viscosity of which is increased at least three-fold by the presence of a sufficient amount of polydialkylsilalkylene polymer.
