Methods and systems for breaching a ceramic disk installed in a wellbore during oil and gas well completion and production activities. A ceramic disk dissolves with a strong acid. Additionally, the strong acid is further used to stimulate a reservoir. The strong acid can be introduced to the wellbore through coiled tubing or directly from the surface.

Examples described herein provide for modeling acid flow for acid stimulation of a formation. An example method includes receiving data about the acid stimulation. The method further includes modeling, by applying the data about the acid stimulation to a model, a wormhole velocity of an acid injected into the formation during the acid stimulation, wherein the wormhole velocity is a function of a Darcy velocity of the acid. The method further includes determining whether the wormhole velocity satisfies a wormhole velocity threshold. The method further includes, responsive to determining that the wormhole velocity fails to satisfy the wormhole velocity threshold, modifying a stimulation parameter to adjust the wormhole velocity of the acid. The method further includes performing the acid stimulation based at least in part on the modified stimulation parameter.

An acid mixture includes hydrochloric acid, a monoamine corrosion inhibitor, and at least one of a diamine corrosion inhibitor and an acid additive. A method for inhibiting corrosion in an acid treatment operation includes introducing an acid mixture comprising hydrochloric acid and a monoamine corrosion inhibitor into at least one of a subterranean formation and subterranean wellbore. The method also includes maintaining the amount of the monoamine corrosion inhibitor in the acid mixture in the subterranean formation and/or the subterranean wellbore in a range of 10 ppm to 400 ppm for the duration of the acid treatment operation. The corrosion rate of steel parts of an acidic fluid circulation system in the acid mixture may be within an acceptable corrosion rate in a temperature range of 20° C. to 135° C.
