Method of and composition for the treatment of unconsolidated sandy formations to stabilize the formation comprising injecting a treating composition consisting essentially of, on a volume basis, 10 to 25% of furfuryl alcohol, 1-4% of a nonionic dispersing surfactant, 1-4% of water, 0.5-1.5% of a silane coupling agent, 1-5% of a catalyst, 5-15% of a low in aromatics petroleum distillate fraction and 47 to 76% of a high in aromatics petroleum fraction, into said sand formation, effecting polymerization of said furfuryl alcohol, and forming a fluid permeable consolidated sand in said formation.
