The chemistry of sour taste and the strategy to reduce the sour taste of beer

Food Chemistry, 2015
The contributions of free hydrogen ions, undissociated hydrogen ions in protonated acid species, and anionic acid species to sour taste were studied through sensory experiments. According to tasting results, it can be inferred that the basic substance producing a sour taste is the hydrogen ion, including free hydrogen ions and undissociated hydrogen ...

Reservoir Souring: Analysis of Surveys and Experience in Sour Waterfloods

Proceedings of SPE Annual Technical Conference and Exhibition, 1997
Abstract Mechanisms of reservoir souring are reviewed in general. A survey was conducted on several seawater and source-water floods to determine the factors that could be responsible for reservoir souring. Data from Shell's offshore Gulf of Mexico field (Cognac Platform) were analyzed more closely, and the results ...

Microbial induced mineral precipitations caused by nitrate treatment for souring control during microbial enhanced oil recovery (MEOR)

International Biodeterioration & Biodegradation, 2018
Microbiologically active environments, like oil reservoirs, can suffer a range of problems due to the presence of sulfate-reducing microorganisms. These include, but are not limited to: H2S formation, souring and corrosion.

Reservoir souring control using benzalkonium chloride and nitrate in bioreactors simulating oil fields of western India

International Biodeterioration & Biodegradation, 2018
Oilfields located in western India produce crude by injection of large amounts of water during secondary oil recovery. This water is obtained from underground aquifer and contains 5 mM sulfate approximately.

Prediction of Souring in Infill Wells using Standalone Extended 2D Simulator for a Malaysian Offshore Field

Day 2 Tue, November 12, 2019, 2019
Hydrogen sulfide (H2S) production in a sea water injected, high temperature offshore reservoir is causing concern, because the existing wells and facilities are not designed for sour service.

Bioreactor for Accurately Assessing Biocide Effectiveness in Controlling Biogenic Souring in Mature Oil Wells

SPE Journal, 2018
Biocide injections are used for controlling biological souring in mature oil wells, but unpredictable results of such practices are also frequently reported.

A Comparison of Chemistries Intended to Treat Reservoir Souring

Corrosion, 2018
The presence of hydrogen sulfide (H2S) in a reservoir poses a major threat to oilfield asset integrity and oil and gas production. In addition to contributing to corrosion, H2S is extremely toxic and devalues produced fluids and gases. Not managing the

Combined Effects of Microbes and Nitrate on SRB Growth, Souring and Corrosion

Corrosion, 2017
Controlling reservoir souring is critical to successful production and asset protection in hydrocarbon recovery. Nitrate injection has been used in water flooding for controlling biogenic sulfide in oil reservoirs.
