<p>A relatively nonvolatile, high molecular weight oil soluble corrosion inhibitor carrier produced by adding at least 40 parts by weight of elemental sulfur per 100 parts by weight dialkyl disulfide oil to an amine activated dialkyl disulfide oil which exhibits corrosion inhibition on its own and in combination with conventional oil based corrosion inhibitor additives. Such a carrier is particularly useful in sustaining a liquid film forming phase at bottomhole conditions of high temperature, high pressure gas wells wherein essentially no pretroleum condensate phase exists. </p> |
