Organic Acid Compositions and Methods of Use in Subterranean Operations

A method comprising:

• providing a treatment fluid that comprises:
• an aqueous base fluid,
• a synthetic cationic gelling agent,
• a plurality of particulates, and
• an organic acid;
• introducing the treatment fluid into at least a portion of a subterranean formation having a temperature of above about 275° F.;
• depositing the particulates into the subterranean formation while the treatment fluid forms at least one void in the subterranean formation;
• wherein the viscosity of the treatment fluid in the subterranean formation is greater than about 20 cP for at least 20 minutes at temperatures higher than about 275° F.

A method comprising:

• providing a treatment fluid that comprises:
• an aqueous base fluid,
• a synthetic cationic gelling agent,
• one or more organic acids or salts thereof, and
• one or more inorganic acids or salts thereof;
• allowing at least a portion of the treatment fluid to react with at least a portion of a subterranean formation so that at least one void is formed in the subterranean formation wherein the viscosity of the treatment fluid in the subterranean formation is greater than about 20 cP for at least 20 minutes at temperatures higher than about 275° F.

A method comprising:

• providing a treatment fluid that comprises:
• an aqueous base fluid,
• a acrylamide/2-(methacryloyloxy)ethyltrimethylammonium methyl sulfate copolymer gelling agent,
• formic acid or a salt thereof;
• hydrochloric acid or a salt thereof;
• introducing the treatment fluid into at least a portion of a subterranean formation having a temperature of above about 275° F.;
• forming at least one void in the subterranean formation with the treatment fluid, wherein the viscosity of the treatment fluid in the subterranean formation is greater than about 20 cP for at least 20 minutes at temperatures higher than about 275° F.
