.... In low temperature fields, main contributor to the H2S production was identified as biogenic process, where microorganisms catalyzed the sour gas production. Conventionally, sulphate reducing microorganism was always blamed as the culprit in contributing towards H2S production. However, abundance...

... Abstract Petroleum-transporting infrastructure can experience severe corrosion in the presence of microbial biofilms, a process termed microbially-influenced corrosion (MIC). However, not all microorganisms are corrosive and distinguishing corrosive from benign biofilms remains challenging...

A total of 30 metagenomes were collected from the 6 process stages and identification and quantification of the major microbial taxa from...

... will have a profound impact on data collection, quality of data and assessment of microbiological threats in the field. INTRODUCTION The presence of microorganisms in natural environments (oilfield reservoirs) and engineered systems (flowlines and separation facilities) has been associated with problems...

... Abstract Microbiologically influenced corrosion (MIC) potential of halophilic (salt-loving) microorganisms have gained increased interests in recent years due to the expansion of industrial operations in saline environments i.e. shale. Survey of multiple shale reservoirs across the continent...

... energized microorganisms in Daqing oilfield with low permeability reservoirs was proposed. Firstly, the number of microorganisms in samples taken from production and injection wells in the target block was measured. Based on the obtained results, the condition for the use of MEOR method in the studied well...

...ABSTRACT ABSTRACT Hydrogen sulfide gas produced by sulfate reducing microorganisms (SRM) creates significant challenges in the petroleum industry including corrosion concerns, product devaluation, and significant health risks. Biocides and inhibitors are often employed to control...

.... Using culture-based and molecular culture-independent methods, we evaluated bacterial characteristics in bentonites compacted to bulk densities of 1.25 g/cm 3 and 1.5 g/cm 3 after one-year in-situ incubation in MaCoTe borehole modules. Abundance of aerobic and anaerobic microorganisms...

Ethanol is capable of being metabolized by various microorganisms serving as a carbon source for them. Under favorable conditions, bacteria and fungi can form biofilms and participate actively...

... ABSTRACT A major problem for the management of oil and gas pipelines is corrosion influenced by microorganisms particularly, bacteria. The present study focuses on the influence particularly of the sulfate reducing bacteria on the internal corrosion of water injection pipelines. The research...
