Smith, F M

A method is described for consolidating loose sand formations, particularly incompetent sand formations surrounding a well bore. The method has the following steps: (1) heating with steam; (2) displacing a heat- curable, resin-forming, furfuryl alcohol composition into the heated zone; and (3) continuing to displace steam (or a gas such as nitrogen, carbon dioxide, and methane) through the impregnated formation to maintain permeability while the resin is cured. The method is of particular economical advantage when used in conjunction with an existing steam stimulation equipment is already on the site, with the cost of the resin-forming material being the main nonlabor consolidation expense. Since steam stimulation usually involves multiple entry wells, the process is of particular practical advantage and utility when used in conjunction with steam stimulation. (3 claims)
