Keywords: residual oil, hydrogen sulfide, reservoir water, relict and biogenic hydrogen sulfide, zonal distribution of hydrogen sulfide, monitoring of hydrogen sulfide content in residual oils
Annotation:
The article discusses the reasons for hydrogen sulfide formation in the flooded fields when developing residual oil reserves. Two reasons for hydrogen sulfide formation in the reservoir are shown: relict and biogenic. The influence of the water injected into the reservoir on the change of hydrogen sulfide content in the extracted products is shown. Analytical data of the deposits containing both relict and biogenic hydrogen sulfide for reservoir oils of different composition, which are created by using the oil properties database, are presented.
