MIC Susceptibility Screening
Weighted screen for microbiologically-influenced corrosion from fluid chemistry, temperature, flow regime, deposits, and (if available) TM0194 bacteria counts. Per NACE TM0194 / API RP 571.

Engineering Basis
Weighted score: free water (necessary), T 20-50 °C (SRB optimum), low/stagnant flow, sulfate/nitrate, deposits, near-neutral pH, elevated bug counts.
Score ≥11 High, 6-10 Moderate, <6 Low; no free water ⇒ Low.
Monitoring per NACE TM0194 (SRB/APB serial dilution); consider qPCR/MMM.
