Acid precursor in divalent brines for cleaning up water-based filter cakes |
| abstract |
A method may include circulating a breaker fluid into a wellbore, where the breaker fluid includes a base fluid of divalent brine having an amount of free water therein; a primary breaker; and a secondary breaker present in an amount less than the primary breaker, where the primary breaker is either a hydrolysable ester of a carboxylic acid or an iminodiacetic acid, and the secondary breaker is the other of the hydrolysable ester of a carboxylic acid or an iminodiacetic acid. |
