Abstract

The present invention described a resin composition comprising from about 5% to about 30% phenol, from about 40% to about 70% phenol formaldehyde, from about 10 to about 40% furfuryl alcohol, from about 0.1% to about 3% of a silane coupling agent, and from about 1% to about 15% of a surfactant and methods of using of that resin in controlling particulate flowback from a subterranean formation.

1 . A method of controlling proppant flowback from a fracture in a subterranean zone comprising the steps of: 
 providing a resin composition comprising: 
 from about 5% to about 30% phenol;

 from about 1% to about 15% of a surfactant;  
   providing proppant particles;    coating the resin composition onto at least a portion of the proppant particles to create resin-coated proppant particles;    introducing the resin-coated proppant particles into the subterranean fracture; and,    allowing the resin on the resin-coated proppant to substantially cure.

       8 . The resin of  claim 7  wherein the silane coupling agent is N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, n-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane, or combinations thereof.  
   
   
       9 . The resin of  claim 7  wherein the surfactant is ethoxylated nonyl phenol phosphate ester, a cationic surfactant, a non-ionic surfactant, an alkyl phosphonate surfactant, or combinations thereof.  
   
   
       10 . The resin of  claim 7  further comprising a solvent.  
   
   
       11 . The resin of  claim 10  wherein the solvent comprises 2-butoxy ethanol, butylglycidyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dimethyl sulfoxide, dimethyl formamide, diethyleneglycol methyl ether, diethylene glycol dimethyl ether, ethyleneglycol butyl ether, diethyleneglycol butyl ether, gamma-butyrolactone, butylene carbonate, propylene carbonate, ethylene carbonate, methanol, butyl alcohol, d'limonene, fatty acid methyl esters, or combinations thereof.  
   
   
       12 . A proppant coated with a resin composition wherein the resin composition comprises: 
 from about 5% to about 30% phenol;    from about 40% to about 70% phenol formaldehyde;    from about 10 to about 40% furfuryl alcohol;    from about 0.1% to about 3% of a silane coupling agent; and,    from about 1% to about 15% of a surfactant.    
   
   
       13 . The resin-coated proppant of  claim 12  wherein the silane coupling agent is N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, n-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane, or combinations thereof.
