NACE TM0194-2014

This standard describes field test methods for estimating bacterial populations commonly found in oil and gas systems. Although these techniques have been successful in the oil field, they are not the only methods that are used. Regardless of the method chosen, all techniques should be applied in a consistent manner. It should be recognized that transportation of samples from the field before analysis may significantly change the viability of the bacteria and therefore, whenever practical, analysis should be initiated in the field. It is not the intent of this standard to exclude additional techniques that can be proved useful. However, caution should be exercised with any technique that is at variance from those outlined here.
