All oil and gas waters contain bacteria (such waters include produced water, seawater, injection water, frac fluids, drilling fluids, and completion brines). One of the more damaging bacteria is sulfate-reducing bacteria (SRB), causing operational and health risks.

The presence of SRB, which are found from reservoir to refinery, results in the following:

The traditional API RP 38 serial dilution method takes 28 days because it relies on bacterial reproduction in growth media. Hach's BART biodetector takes 8 days for the same reason. qPCR runs faster but reads RNA, not viable organisms, and produces well-documented false positives.

Frac flowback
Production runs SRB on twelve flowback samples at the pad. Twenty-four hours later, biocide loading is adjusted by tank. No samples shipped. No 28-day wait.

Pipeline integrity
A pipeline operator tests ferrous iron, sulfide, and SRB at each pig station weekly. Trend data drives a 19 percent biocide spend reduction without elevating MIC risk.

Step 1: Fill the cuvettes with sample.

our test doesn’t require toxic, harmful materials and can be conducted anaerobically. Safely enhancing the accuracy of the SRB detection.

Step 2: Observe over 24 hours

H₂S Positive

H₂S Negative

SRB Positive

SRB Negative
