QuantArray® MIC, an advanced qPCR method, rapidly detects and quantifies key microorganisms and functional genes responsible for microbiologically influenced corrosion (MIC) and oilfield souring in a single analysis.

MI QuantArray MIC Logo

QuantArray® MIC ADVANTAGES:

Icon-Accurate

ACCURATE

Direct analysis of sample DNA removes the need to grow the bacteria thus eliminating biases associated with traditional approaches (e.g. plate counts and BARTs).

icon-Quantitative

QUANTITATIVE

Absolute quantification of concentrations of total bacteria, total archaea, and specific microbial groups to monitor abundances over time or in response to treatment. Results reported as cells/mL, cells/g, etc.

Icon-Sensitive

SENSITIVE

Practical Detection Limits (PDL) are as low as 100 cells per sample with a dynamic range over seven orders of magnitude.

icon-Specific

SPECIFIC

Target specific bacterial groups (e.g. sulfate reducing bacteria, methanogens) associated with MIC.

icon-CostEffective

COST-EFFECTIVE

In a single analysis, quantify total bacteria, total archaea, and a broad spectrum of common MIC microorganisms (e.g. SRB, SRA, methanogens, IRB, FeOB, etc.) Same accuracy and turnaround time as CENSUS®qPCR but more comprehensive and even more cost-effective.

icon-Customizable

CUSTOMIZABLE

Assays are available for quantification of MIC associated microbes for which traditional assays are not available, and custom assays can be developed to fit your needs.

icon-Flexible

FLEXIBLE

QuantArray® MIC analysis can be performed on almost any type of sample (water, solids, corrosion coupons, swabs, pigging debris, scrapings, Bio-Traps®, and others).

HOW TO USE QuantArray® MIC:

QuantArray® MIC provides simultaneous quantification of key organisms and functional genes involved in MIC, as well as oilfield souring, proving a more comprehensive assessment. Evaluation of the microorganisms present within a system permits managers to:

  • Quantify MIC bacteria and accurately assess corrosion potential
  • Evaluate the effectiveness of treatments and O&M measures

All of the organisms listed above are included in a single QuantArray® qPCR analysis.
