H2S Properties and Characteristics

Mud Plant

§  Hydrogen Sulfide is highly Toxic

§  colorless gas

§  Hydrogen Sulfide consists of two Hydrogen atoms and one Sulfur atom

§  H2S is soluble in Drilling and Formation Fluids 

§  H2S is Highly Flammable Gas  in between 4.3% and 46%

§  H2S is Corrosive to Metals and Elastomer Seals

§  H2S is Heavier than Air by 20%

§  When burning H2S another toxic gas is formed which is SO2

§  H2S has a rotten egg odor at low Concentrations ( from 0.0047 PPM)
