Thanks for pointing out that PCTL's Hydrolyte works!

Oil or natural gas is considered sour if it has a high percentage of hydrogen sulfide. It has been estimated that 15 to 25% of natural gas in the U.S. may contain hydrogen sulfide. Worldwide, the percentage could be as high as 30%. It has been reported, as well, that new drilling is increasingly being focused on deep gas formations that tend to be sour.

Although the exact number of sour wells are not available, the EPA has reported that in the U.S. “the potential for routine H2S emissions [at oil and gas wells] is significant.”

Exposure to hydrogen sulfide is one of the leading causes of sudden death in the workplace. At concentrations greater than 500 parts per million, inhalation of hydrogen sulfide can lead to immediate collapse and unconsciousness. A single breath at 1,000 ppm results in immediate loss of consciousness, cardiac arrest and death unless the unconscious victim is successfully revived. Unconsciousness and death have occurred in situations of prolonged exposure to hydrogen sulfide at concentrations of 50 ppm. Many occupational and community studies have documented the adverse health effects of exposure to relatively high levels of H2S.

PCTL's Hydrolyte is EPA Approved for use in reducing Hydrogen Sulfide (H2S) in Oil and Gas wells.
