A method of corrosion inhibition using a gelled inhibitor is disclosed. The method comprises consecutively introducing into an annular region of a jacketed pipeline a hydrogel slurried in an environmentally innocuous oil medium and a corrosion inhibitor dissolved in an aqueous medium. The liquid media are contacted to form a gelled corrosion inhibitor in the annulus. The method is particularly useful in buried pipelines where corrosion monitoring is difficult.
