Abstract

This study investigates the source of hydrogen sulfide gas in the oil fields of Siri Island, Persian Gulf Basin, through microbiological and geochemical analyses of output, seawater input, and injection water samples. The findings suggest that reservoir souring is primarily caused by bacterial sulfate reduction, likely triggered by enhanced recovery methods such as water injection. Microbiological tests identified sulfate-reducing bacteria, with Desulfovibrio species being the dominant type, accounting for 81% of the bacteria identified. These bacteria were responsible for hydrogen consumption in the oil reservoir, leading to hydrogen sulfide production. The research concludes that Desulfovibrio bacteria play a critical role in souring processes in Siri Island oil fields. This study provides key insights into microbial mechanisms of reservoir souring, offering valuable information for improving oil recovery strategies and mitigating souring in future operations.

波斯湾西里岛油田注水过程中储层酸化的微生物评价

通过对波斯湾盆地Siri岛油田产出、海水输入和注水样品的微生物学和地球化学分析，探讨了该油田硫化氢气的来源。研究结果表明，储层酸化主要是由细菌硫酸盐还原引起的，可能是由注水等提高采收率的方法引发的。微生物学试验鉴定出硫酸盐还原菌，其中脱硫弧菌属为优势菌种，占鉴定细菌的81%。这些细菌负责油层中的氢消耗，导致硫化氢的产生。研究认为，在西里岛油田的酸化过程中，脱硫弧菌起着至关重要的作用。该研究为油藏酸化的微生物机制提供了关键见解，为提高采收率策略和减轻酸化提供了有价值的信息。

期刊介绍： International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management. A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made. The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
