Tungstate Control of Microbial Sulfidogenesis and Souring of the Engineered Environment
Environmental Science & Technology, 2020Sulfide 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. Here, we present an assessment of tungstate as a selective and potent inhibitor of SRM. Dose-response inhibitor experiments were conducted with a number of SRM

Control of Reservoir Souring by a Novel Biocide
CORROSION 1995, 1995Abstract A previous paper reported that a novel phosphonium biocide (based on tetrakishydroxymethylphosphonium sulphate), dosed to injection water, travelled through the formation and re-emerged in the produced water. It was suggested, at the time, that the biocide might be helping to control produced hydrogen sulphide levels by its ...

Postharvest sour rot control in lemon fruit by natamycin and an Allium extract
International Journal of Food Microbiology, 2022Citrus sour rot caused by Geotrichum citri-aurantii is one of the most important postharvest diseases in citrus fruit, causing huge economic losses. Traditionally, it has been controlled by the postharvest application of guazatine and propiconazole fungicides, but restrictions in their use make it urgent to find an alternative for sour rot management ...

Troubleshooting Nitrate Field Injections for Control of Reservoir Souring
SPE International Symposium on Oilfield Chemistry, 2009Abstract Nitrate addition to injection water has been used to control the development of reservoir souring through microbial production of hydrogen sulfide particularly in seawater floods offshore. Current interest is in the application of this technology to produced water recycle injection (PWRI) systems in onshore fields.

Causes and Control of Microbially Induced Souring
1993Abstract Petroleum reservoirs are harsh environments, but are not devoid of life. Rather, they are functional ecosystems with diverse, and metabolically active microorganisms. Thus, there is the potential for microbial sulfide production in the reservoir when environmental conditions permit.

Overcoming Hazards in Sour Gas Sampling by Controlled Measures
Abu Dhabi International Petroleum Exhibition & Conference, 2016Abstract Objective Sampling and analysis of sour gas is hazardous and can lead to fatality if appropriate safety precautions are not taken. Similarly if improper technique or instrument is used for measurement, it might lead to high error and the results will be unreliable for process control.

Corrosion Control - Deep Sour Gas Production
SPE Annual Technical Conference and Exhibition, 1979Abstract Corrosion in deep high pressure sour gas wells can be successfully controlled. Many problems have been encountered in producing Shell's high pressure sour gas wells producing Shell's high pressure sour gas wells in the Thomasville, Piney Woods, and Southwest Piney Woods Fields.

Control of Corrosion Inhibitor Fouling in a Highly Sour System
CORROSION 2018, 2018Abstract Black tar-like fouling material was driving frequent shut-downs and increasing corrosion in the inlet area of a gas plant that processes lean gas with high acid gas content (68%CH4, 20%CO2 and 12%H2S). Analytical work indicated that the nitrogen containing corrosion inhibitor (CI) polymerized with sulfur compounds (polysulfides,
