Abstract
The reasons for the high content of sulfur compounds in the oil production of reef deposits of the Frasnian stage were identified basing on complex analysis of geological and production data, core study, formation fluid studies, and isotopic composition of formation water. Secondary alterations: dolomitization and sulphatization in carbonate rocks are the reason of different content of hydrogen sulfide in reservoir fluids.
Materials and methods
An integrated approach based on petrographic studies of rocks and geochemical studies of formation fluids (oil, gas, water).
Keywords
hydrogen sulfide, oil, deposits, carbonate reservoir, secondary changes
