Abstract

This disclosure is related to a method of treating a formation, a wellbore, or equipment in a wellbore. The method includes introducing a soluble abrasive material into a wellbore for various oil and gas operations. The method also includes introducing an acidic solution into the wellbore to dissolve at least a portion of the soluble abrasive material to allow for more efficient removal of the soluble abrasive material from the wellbore.

Claims (4)

1. An abrasive slurry used for abrasive perforation operations, the slurry comprising:

a soluble abrasive material wherein the soluble abrasive material is calcium carbonate;

a non-soluble abrasive material wherein the non-soluble abrasive material is selected from the group consisting of sand, gypsum, silica-based products, and a combination thereof, the soluble abrasive material and the non-soluble abrasive material combining to create an abrasive material mixture, the abrasive material mixture having a ratio of non-soluble abrasive material to the soluble abrasive material in a range of from about 10.0 weight percent to about 20 weight percent; and

a carrier fluid for transporting the abrasive materials into the wellbore.
