Inhibition of microbial souring with molybdate and its application under reservoir conditions

, 2021
Souring induced by sulfate reducing microorganisms (SRM) represents a severe problem in the petroleum industry. In addition to conventional biocides and nitrate, alternative SRM inhibitors such as molybdate have been proposed recently for controlling ...

Long-term souring treatment using nitrate and biocides in high-temperature oil reservoirs

, 2020
The biogenic production of hydrogen sulfide (H2S) by sulfate-reducing bacteria (SRB) and consequently the souring of reservoirs are still major problems in oil industry. Biocides and/or nitrate are used to control SRB activity in oil reservoirs, but long-

The contribution of nitrate-reducing bacterium Marinobacter YB03 to biological souring and microbiologically influenced corrosion of carbon steel

, 2020
We have previously studied the effect of nitrate addition on the souring caused by sulfate-reducing bacteria (SRB). It revealed that the nitrate addition could suppress the growth of SRB and stimulate the growth of nitrate-reducing bacteria (NRB).

Tungstate Control of Microbial Sulfidogenesis and Souring of the Engineered Environment.

Environmental Science and Technology, 2020
Sulfide accumulation in oil reservoir fluids (souring) from the activity of sulfate-reducing microorganisms (SRM) is of grave concern because of the associated health and facility failure risks.

Microbial Ecology Metrics to Assess the Effect of Biocide on Souring Control and Improve Souring Modelling

, 2021
Reservoir souring is a long-standing issue for the oil and gas industry caused by sulfate-reducing microorganisms (SRM) producing H2S from sulfate ions.

Mechanisms for the Sour Taste

2021
Sour, the taste of acids, provides important sensory information to prevent the ingestion of unripe, spoiled, or fermented foods. In mammals, acids elicit disgust and pain by simultaneously activating taste and somatosensory neurons innervating the oral cavity.
