Treatment fluids comprising relative permeability modifiers and methods of use
Treatment fluids for and methods of treating subterranean formations are provided. In certain embodiments, a method is provided comprising providing a treatment fluid comprising a relative permeability modifier, a delayed filter cake breaker, and a carrier fluid, contacting at least a portion of a filter cake in a subterranean formation with the treatment fluid, and removing at least a portion of the filter cake.
1. A method comprising:
providing a treatment fluid comprising a relative permeability modifier, a delayed filter cake breaker, and a carrier fluid;
wherein the delayed filter cake breaker comprises one or more components selected from the group consisting of an acid-generating compound, an azo compound, and any combination thereof;
contacting at least a portion of a filter cake in a subterranean formation with the treatment fluid; and
removing at least a portion of the filter cake.
2. The method of claim 1 wherein the acid-generating compound comprises at least one acid-generating compound selected from the group consisting of: an ester; an aliphatic polyester; an ortho ester; a poly(ortho ester); an ortho ether; a poly(ortho ether); a lactide; a poly(lactide); a glycolide; a poly(glycolide); an ε-caprolactone; a poly(ε-caprolactone); a hydroxybutyrate; a poly(hydroxybutyrate); an anhydride; a poly(anhydride); an aliphatic carbonate; an aliphatic polycarbonate; an amino acid; a poly(amino acid); ethylene oxide; poly(ethylene oxide); a polyphosphazene, any copolymer thereof, and any derivative thereof.
3. The method of claim 1 wherein the acid-generating compound comprises at least one acid-generating compound selected from the group consisting of: a formate ester; an acetate ester; a lactate ester; ethylene glycol monoformate; ethylene glycol diformate; diethylene glycol diformate; glyceryl monoformate; glyceryl diformate; glyceryl triformate; triethylene glycol diformate; a formate ester of pentaerythritol; glyceryl triacetate; methyl lactate; butyl lactate; and any derivative thereof.
4. The method of claim 1 wherein the relative permeability modifier comprises at least one relative permeability modifier selected from the group consisting of: a water-soluble, hydrophobically modified polymer; a water-soluble, hydrophilically modified polymer; a water-soluble polymer without hydrophobic or hydrophilic modification; and any combination thereof.
5. The method of claim 1 wherein the relative permeability modifier is present in an amount of about 0.05% to about 1.5% by weight of the treatment fluid.
6. The method of claim 1 , wherein the treatment fluid further comprises a relative permeability modifier breaker.
7. A method comprising:
providing a treatment fluid comprising a relative permeability modifier, a delayed filter cake breaker, a plurality of particulates, and a carrier fluid;
wherein the delayed filter cake breaker comprises one or more components selected from the group consisting of an acid-generating compound, an azo compound, and any combination thereof;
contacting at least a portion of a subterranean formation with the treatment fluid; and
depositing at least a portion of the plurality of particulates in at least a portion of the subterranean formation to form a gravel pack while removing at least a portion of a filter cake contained in at least a portion of the subterranean formation.
8. The method of claim 7 wherein the acid-generating compound comprises at least one acid-generating compound selected from the group consisting of: an ester; an aliphatic polyester; an ortho ester; a poly(ortho ester); an ortho ether; a poly(ortho ether); a lactide; a poly(lactide); a glycolide; a poly(glycolide); an ε-caprolactone; a poly(ε-caprolactone); a hydroxybutyrate; a poly(hydroxybutyrate); anhydride; a poly(anhydride); an aliphatic carbonate; an aliphatic polycarbonate; an amino acid; a poly(amino acid); ethylene oxide; poly(ethylene oxide); a polyphosphazene, any copolymer thereof, and any derivative thereof.
9. The method of claim 7 wherein the acid-generating compound comprises at least one acid-generating compound selected from the group consisting of: a formate ester; an acetate ester; a lactate ester; ethylene glycol monoformate; ethylene glycol diformate; diethylene glycol diformate; glyceryl monoformate; glyceryl diformate; glyceryl triformate; triethylene glycol diformate; a formate ester of pentaerythritol; glyceryl triacetate; methyl lactate; butyl lactate; and any derivative thereof.
10. The method of claim 7 wherein the relative permeability modifier comprises at least one relative permeability modifier selected from the group consisting of: a water-soluble, hydrophobically modified polymer; a water-soluble, hydrophilically modified polymer; a water-soluble polymer without hydrophobic or hydrophilic modification; and any combination thereof.
11. The method of claim 7 wherein the relative permeability modifier is present in an amount of about 0.05% to about 1.5% by weight of the treatment fluid.
12. The method of claim 7 , wherein the treatment fluid further comprises a relative permeability modifier breaker.
