Abstract

HYDROGEN SULFIDE (H2S) is generally an undesirable component of natural gas. H2S not only can critically affect the economic proportion of hydrocarbon gas in the reservoir, but also it is highly toxic and corrosive for production equipment. Therefore the ability to predict the occurrence of H2S in undrilled prospects would be a very useful idea in decrease of gas exploration and production risk. A variety of discrete sources for H2S in petroleum have been identified including: 1-Bacterial reduction of sulfate to H2S (BSR) 2-Thermal decomposition of sulfides in kerogen and/or oil. thermochemical reduction of sulfate to H2S (TSR). In natural gas reservoirs in the south of Iran have been seen the sign of TSR in particular in lower Dalan gas reservoir.Significant enrichment in nitrogen, occurrence of isotopically light CO2 and depletion in the light carbon isotope of methane, ethane and propane in the gas reservoir that buried in more than 4km . These peculiarities suggest that the composition of gases in this zone was modified by the process of the thermochemical reduction of sulfate.
