Viscoelastic surfactant gel for perforation operations

A method for well treatment comprising:

• introducing a viscoelastic surfactant gel and a perforating fluid into a wellbore such that the perforating fluid is placed in a casing interval to be perforated and the viscoelastic surfactant gel is placed above the casing interval to be perforated, wherein the perforating fluid comprises a water wetting surfactant;
• forming one or more perforation channels in the casing interval to be perforated while the viscoelastic surfactant gel is disposed in the wellbore;
• allowing the perforating fluid to leak off into the formation through the one or more perforation channels;
• and
• allowing the viscoelastic surfactant gel to form a plug in the one or more perforation channels.

• disposing a perforating gun into the wellbore such that the perforating fluid is disposed between the perforating gun and a casing of the wellbore;
• forming one or more perforation channels in the interval of the wellbore, wherein the one or more perforation channels extend through the casing and into a subterranean formation penetrated by the wellbore;
• and
• allowing the perforating fluid to leak off into the formation through the one or more perforation channels.
