    Abstract: A relatively nonvolatile, high molecular weight sulfur solvent produced by activating a dialkyl disulfide oil by the addition of a relatively high molecular weight predominantly aliphatic amine (e.g., a N-alkyl-1,3-propane diamine) and optionally further increasing the molecular weight by the addition of elemental sulfur. Such a sulfur solvent is particularly useful in sustaining a liquid phase at bottomhole conditions for high temperature, high pressure sour gas.

    Abstract: A relatively nonvolatile, high molecular weight corrosion inhibitor and inhibitor carrier produced by activating a dialkyl disulfide oil by the addition of a relatively high molecular weight aliphatic amine (e.g., a fatty amine, particularly the N-alkyl-1,3-propane diamines) and optionally further increasing the molecular weight by the addition of elemental sulfur, which exhibits corrosion inhibition on its own and in combination with a conventional oil base corrosion inhibitor additive. Such a composition is particularly useful in sustaining a liquid film forming phase at bottomhole conditions for high temperature, high pressure gas wells wherein essentially no petroleum condensate phase exists.

    Abstract: A relatively nonvolatile, high molecular weight sulfur solvent produced by adding at least 40 parts by weight of elemental sulfur per 100 parts by weight dialkyl disulfide to an amine activated dialkyl disulfide oil. Such a sulfur solvent is particularly useful in sustaining a liquid phase at bottomhole conditions for high temperature, high pressure wells.

    Abstract: 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.
