Rosenberg, M

Unconsolidated sands are permanently consolidated by impregnation with furfuryl alcohol or a prepolymer of furfuryl alcohol. The furfuryl alcohol is cured to form a resin bonding the particles together by passing a gaseous catalyst such as HC1 in either the pure state or diluted with inert gas through the impregnated sands. The resin-forming material is introduced into the formation prior to its contact with the catalyst. By this technique, the criticality of time is avoided. Unexpected delays or accidents can be accommodated without resulting resinification in the equipment or well bore. This permits much greater flexibility in conducting well operations and relieves the well workers of pressures which might otherwise lead to mistakes and accidents. (12 claim)
