Abstract
A series of novel oil-dispersible corrosion inhibiting solutions are disclosed which contain dicyclopentadiene (3a, 4, 7, 7a-tetrahydro-4, 7 methanoindene) sulfonate salts along with an organic corrosion inhibitor in a low molecular weight solvent. The inhibiting solutions containing dicyclopentadiene sulfonate salts are effective in dramatically reducing corrosion rates in the oil field, especially pitting from hydrogen sulfide.
