... direction. Furthermore, investigation carried out by the Most Probable Number (MPN) Serial Dilution technique in accordance with NACE documents TM0194-2014 ¹⁴ and TM0106-2016-SG ¹⁵ showed low to nil SRB counts, and very high General Aerobic Bacteria (GAB...

... of the shortfalls with current microbial enumeration technology and demonstrates that qPCR can provide an appropriate balance of speed and accuracy over other field-ready enumeration techniques for measurement of total bacteria or sulfate-reducing bacteria (SRB). The study also demonstrates the need to undertake...

... chemical treatments, shear stress, and predators. Within the biofilm matrix, microorganisms thrive in conditions responsible for promoting a corrosive environment. The types of bacteria responsible for corrosion vary from system to system. In this study we used a novel biomonitoring system installed in 26...

... time. To overcome the MIC challenges, Saudi Aramco, in collaboration with international company, has developed an Autonomous Microbe Sensor (AMS) technology (Bacteria Sensor) to detect & measure in real-time & on-line the bacteria counts in sea water injection system. AMS that is based...

...Abstract Based upon the observation that an oilfield appeared to possess an endospore-forming microbial population that was selected for by its microbiocide program, a hypothesis was formed that exposing endospore-capable bacteria to low dosing of microbiocides, particularly to those chemistries...

...Testing also determined that the method was not affected by the presence of hydrocarbons or production chemicals. Given that bacteria samples degrade and change shortly after collection the new method also required to be compatible with oil and gas field conditions. The new method...

... for microbiological analysis of samples collected from underneath the polyethylene encasement. The kit enumerates viable bacteria belonging to the following groups: anaerobic bacteria (ANA), acid-producing bacteria (APB), iron-related bacteria (IRB), low nutrient bacteria (LNB) – Slime formers and sulfate-reducing...

...Specific microorganisms, Sulfate Reducing Bacteria (SRB) and Acid Producing Bacteria (APB), isolated from the water samples were enriched applying commercial “bug bottles” and used as the test inoculum for a biocide selection study. DNA was extracted on-site from several locations and later...

... of bacteria and archaea are capable of generating H₂S from an array of sulfur-containing compounds, although the key enzymes involved are relatively well conserved. We have identified a class of inhibitory molecules that abrogate sulfidogenesis by numerous diverse microbial populations found within...

...THPS and 1,3-Dimethylol-5,5-dimethylhydantoin (DMDM Hydantoin) are both biocides often used individually, and very effectively, in many industrial applications to control the proliferation of undesired bacteria. THPS is already widely used in hydraulic fracturing, and provides a quick kill...

...Abstract Refining industry cooling systems are prone to many different corrosion deterioration mechanisms, one of which is Microbiologically Influenced Corrosion (MIC). Bacteria are ubiquitous, they have been implicated in a number of major failures and their control measures have a high economic...

Bacterial action plays a part in pitting and crevice corrosion in natural seawater; aerobic bacteria colonize the steel surface...

... sandstone to 10 mL of the injection fluid. The injection fluid/biocide was incubated with the crushed sandstone for 24 hours (30°C) to allow ample time for adsorption to occur. Abstract It is well understood that sulfate reducing bacteria (SRB), acid-producing bacteria (APB), and facultative anaerobic...

... of treatments applied at 1:1 to 1:4 GLUT to DMO active ratios were highly synergistic against bacteria. This ratio provided a rapid kill of sulfate-reducing bacteria (SRB) and acid-producing bacteria (APB), as well as extended control in downhole conditions. Testing conditions were designed to simulate downhole...

... (if not hundreds) of different genera of bacteria and archaea. Importantly, microbes can possess multiple types of metabolic pathways that can be utilized in different environments, therefore necessitating their inclusion in multiple classes: NACE 31205 provides detailed descriptions of many of these eight classes...

This knowledge will assist in the design of better prevention, treatment, and control strategies for microbial activity. A series of in-depth analyses were carried out on a database of field samples submitted...
