Adenosine Testing and its Interpretation in Oil and Gas Field Microbial Status

Microorganisms can cause multiple threats in oil and gas production (EFC 9 ), injection and fracturing operations. Those threats range from production downtime due to microbial influenced corrosion (MIC) downhole and on surface equipment, to formation souring, as well as flow disruption caused by overgrowth of biomass in flow lines ((EFC29 ). Adenosine analysis, particularly ATP field tests  (NACE, TM0212) (NACE, TM0194), have been introduced into oil and gas for microbial status assessment. It facilitates a fast field screening Test for microbial status  comparing to the labour intensive and time consuming culturing techniques. However, the challenge is on results interpreting. Understanding the adenosine, adenosine testing and their biological implication are utmost important to assess the oil and gas field microbial status.

Adenosine test,including ATP, ADP and AMP,  provides a fast, efficient screening tool for oil and gas microbial status assessment. It is important for corrosion engineer to understand the principle and limitation of this tool, as well as its difference to traditional culturing techniques. It is an ongoing challenge to monitor the microbial status and validate the adenosine testing results with other field culturing techniques.

    Hey there, I think your website might be having browser compatibility issues. When I look at your website in Firefox, it looks fine but when opening in Internet Explorer, it has some overlapping. I just wanted to give you a quick heads up! Other then that, great blog!
