Abstract
A method for water compatible chemical in situ sand consolidation with oil soluble furan resin. The three step water compatible in situ chemical consolidation uses thermally and chemically stable furan resin. The placement of the resin is by phase separation rather than by conventional fluid displacement. The method uses the injection of resin/water miscible organic solvent solution followed by a spacer volume of water and acid catalyst injection.
