A method is described for consolidating loose sand formations, particularly incompetent sand formations surrounding a well bore. In the method, combustibles are burned in the incompetent formation to heat the formation. The combustion step is followed by the injection of a liquid resin-forming material which, in turn, is followed by the injection of gas to displace a portion of a resin-forming material farther outward into the formation. Heat remaining in the formation following the combustion step raises the temperature of the resin- forming liquid to cause resinification. Furfurly alcohol and partial polymers of furfuryl alcohol are preferred resin-forming materials. (4 claims)
