13. A method of temporarily sealing off perforations comprising:
-
providing a carrier fluid comprising degradable balls that comprise a carboxylic acid, a fatty alcohol, a fatty acid salt, a fatty ester, or a combination thereof; introducing the carrier fluid to the subterranean formation during a treatment; allowing the carrier fluid to penetrate at least a portion of the perforation; allowing the degradable balls to divert at least a portion of the treatment fluid; and allowing the degradable balls to degrade in the subterranean formation such that the perforation is re-opened. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
