A method for removing liquid buildup in gas wells may include introducing a first aqueous solution and a second aqueous solution into the wellbore such that the first aqueous solution and the second aqueous solution may intermix within the wellbore. The first aqueous solution may contain a nitrogen-containing compound and the second aqueous solution may contain a nitrite-containing compound and a foaming agent. The method may further include maintaining the intermixed solution in the wellbore such that gas, heat, and foam may be generated, and removing the excess fluid from the wellbore. Furthermore, the method may include introducing an acid or acid precursor into the wellbore, releasing an acid from the acid precursor into the intermixed solution, and maintaining the acid with the intermixed solution in the wellbore to adjusted the pH of the intermixed solution to less than 7.0.
