Johnson, B J; Totty, K D; Young, B M

An acid-curable consolidating fluid, consisting of furfuryl alcohol resin and a resin solvent compound selected from the group consisting of lactones, dioxanes, pyrollidones, aldehydes, and phenols is pumped into the unconsolidated sand or earth formation. This mixture is followed by an oil overflush solution having a relatively high degree of immiscibility with the consolidating fluid and containing a low molecular weight organic acid or acid-producing chemical dispersed or dissolved in it. A small quantity of diesel oil spacer may be used between the resin and catalyst solution if desired. The overflush functions to remove the excess bonding material from the existing pore spaces to provide the necessary permeability, and its acid-producing components subsequently harden the remaining film of consolidating fluid convering the sand or earth particles, thereby consolidating or stabilizing the loose formation.
