    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.

    Abstract: Methods may include circulating a breaker fluid into a wellbore, the breaker fluid containing: a base fluid, a peroxide source, and a catalyst. In another aspect, methods may include drilling a wellbore with a drilling fluid containing a catalyst, and circulating a breaker fluid into a wellbore, the breaker fluid containing a base fluid, and a peroxide source. In yet another aspect, methods may include treating a contaminated fluid with a treatment fluid containing a base fluid, a peroxide source, and a catalyst.

    Abstract: A wellbore fluid for dissolving a filtercake includes a chelating agent and an aqueous solution of carboxylate salt. The concentration of the chelating agent is up to 50 percent volume per volume (v/v) in the aqueous solution of carboxylate salt. A method of treating a well includes preparing a wellbore fluid up to 50 percent volume per volume (v/v) chelating agent in an aqueous solution of carboxylate salt. The method further includes emplacing the wellbore fluid downhole such that the wellbore fluid dissolves a filtercake in the well.
