SRB/APB Bacterial Sampling (Sessile, Planktonic)
Bacteria can be a mechanism in corrosion in oil and gas production, and is commonly referred to as Microbial Influenced Corrosion (MIC). RYSCO Corrosion Services is able to provide sampling, inoculation, and reporting with respect to the most common types of oilfield bacteria. The accepted standard for bacterial testing in oilfield produced water is Serial Inoculation via Dilution. RYSCO Corrosion Services is able to test for Planktonic (free floating) and Sessile (attached) Sulfate Reducing Bacteria (SRB) and Acid Producing Bacteria (APB) through this method. Techniques employed adhere to NACE TM0194 ‘Field Monitoring of Bacterial Growth in Oil and Gas Systems’.
Additional bacterial testing may be completed through utilization of BARTTM tests to identify Iron Related Bacteria (IRB), Sulfate Reducing Bacteria (SRB), Slime Forming Bacteria (SLYM), Heterotrophic Aerobic Bacteria (HAB), Denitrifying Bacteria (DN), Nitrifying Bacteria (N), and Acid Producing Bacteria (APB).
Observations of bacterial colonies on surfaces is also available through the use of Scanning Electron Microscopy (SEM), in situations where it may not be possible to incubate bacteria at system temperatures, or there is insufficient water for inoculation.
