Abstract: In one embodiment, a retarded acid system comprises an aqueous acid and a retarding surfactant. The aqueous acid may comprise from 5 wt. % to 25 wt. % of a strong acid, that is, an acid having a Ka greater than or equal to 0.01. The aqueous acid may further comprise from 75 wt. % to 95 wt. % water. The retarding surfactant may have the general chemical formula R—(OC2H4)x—OH where R is a hydrocarbon having from 11 to 15 carbon atoms and x is an integer from 6 to 10. The retarding surfactant may have a hydrophilic-lipophilic balance from 8 to 16.

Abstract: A method and system for controlling unwanted water production from a water-producing zone in a subterranean formation are provided. An exemplary method includes flowing an alkaline suspension of nanosilica particles into a wellbore such that it contacts the water-producing zone, and flowing a formate salt solution into the wellbore such that it contacts the alkaline suspension in the water-producing zone producing a composition. The wellbore is shut in a duration of time sufficient for the composition to form a gel that is impermeable to fluid flow.
