Abstract
A method for removing wellbore deposits includes the steps of providing a first treatment solution comprising a nitrite salt and a second treatment solution comprising sulfamic acid into the wellbore, allowing the first and second treatment solutions to mix and form a cleaning fluid, and maintaining the first and second treatment solutions in reactive connection. The first and second treatment solutions are maintained in reactive connection to initiate reaction of the sulfamic acid and the nitrite salt to generate an acidic bisulfate salt, heat, and nitrogen gas; remove organic and inorganic deposits from the wellbore; and stimulate the walls of the wellbore by dissolving minerals in the walls of the wellbore with the generated acidic bisulfate salt. Organic and inorganic deposits are removed from the wellbore by liquefying the organic deposits upon elevation of the temperature with the generated heat and breaking down the inorganic deposits with the acidic bisulfate salt.
