WebHydrogen sulfide (H 2 S) occurs in approximately 40% of all wells. Wells with large amounts of H 2 S are usually labeled sour; however, wells with only 10 ppm or above can also be labeled sour. Partial pressures above 0.05 psi H 2 S are considered corrosive. The amount of H 2 S appears to increase as the well ages.
