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.
