Assessing Microbial Corrosion Risk on Offshore Crude Oil Production Topsides under Conditions of Nitrate and Nitrite Treatment for Souring [PDF]

Microorganisms, 2022
Oilfield souring is a detrimental effect caused by sulfate-reducing microorganisms that reduce sulfate to sulfide during their respiration process. Nitrate or nitrite can be used to mitigate souring, but may also impart a corrosion risk.

Polymer biodegradation by Halanaerobium promotes reservoir souring during hydraulic fracturing [PDF]

Applied and Environmental Microbiology
Hydraulically fractured shale reservoirs have facilitated studies of unexplored niches in the continental deep biosphere. In high-salinity North American shale systems, members of the genus Halanaerobium seem to be ubiquitous. Polymers like guar gum used

Long-Term Biocide Efficacy and Its Effect on a Souring Microbial Community [PDF]

Applied and Environmental Microbiology, 2021
Reservoir souring is a problem for the oil and gas industry, because H2S corrodes the steel infrastructure, downgrades oil quality, and poses substantial risks to field personnel and the environment.

Using Thermodynamics to Predict the Outcomes of Nitrate-Based Oil Reservoir Souring Control Interventions

Frontiers in Microbiology, 2017
Souring is the undesirable production of hydrogen sulfide (H2S) in oil reservoirs by sulfate-reducing bacteria (SRB). Souring is a common problem during secondary oil recovery via water flooding, especially when seawater with its high sulfate ...

Assessment of the Biogenic Souring in Oil Reservoirs under Secondary and Tertiary Oil Recovery

Energies
The formation of hydrogen sulfide (H2S) in petroleum reservoirs by anaerobic microbial activity (through sulfate-reducing microorganisms, SRMs) is called biogenic souring of reservoirs and poses a risk in the petroleum industry as the compound is ...

Importance of thermodynamics dependent kinetic parameters in nitrate-based souring mitigation studies

Water Research, 2021
Souring is the unwanted formation of hydrogen sulfide (H2S) by sulfate-reducing microorganisms (SRM) in sewer systems and seawater flooded oil reservoirs.

The impact of alkyl polyglycoside surfactant on oil yields and its potential effect on the biogenic souring during enhanced oil recovery (EOR)

Fuel, 2020
The aim of this work is to quantify the effect of using alkyl polyglycoside (APG) surfactant as the main agent for oil recovery and to quantify its potential impact on biogenic souring.

Reservoir souring: sulfur chemistry in offshore oil and gas reservoir fluids

Journal of Petroleum Exploration and Production Technology, 2018
The injection of sulfate-containing seawater into an oil reservoir, for maintaining the reservoir pressure, can promote the growth of sulfate reducing bacteria and archaea near the injection wells, leading to the formation of sulfides such as hydrogen ...

Photoluminescence Spectral Patterns and Parameters of Milk While Souring

Agriculture (Switzerland), 2023
For the efficient production and processing of milk, it is important to control its quality indicators. Optical spectroscopy, in combination with statistical analysis methods, can be a useful method of evaluation due to its speed, non-invasiveness, and ...

Microorganisms’ effect on the wettability of carbonate oil-wet surfaces: implications for MEOR, smart water injection and reservoir souring mitigation strategies

Journal of Petroleum Exploration and Production Technology, 2019
In upstream oil industry, microorganisms arise some opportunities and challenges. They can increase oil recovery through microbial enhanced oil recovery (MEOR) mechanisms, or they can increase production costs and risks through reservoir souring process ...
