Root cause failure analysis.

When wellhead equipment fails, we find out why, so it does not happen again.

  1. Collect

    We gather the failure history, operating conditions and the failed component.

  2. Examine

    We document the failure and examine the part visually and dimensionally.

  3. Test

    Laboratory testing with our partner US Corrosion Services in Houston, Texas, including electron microscopy.

  4. Report

    You receive the root cause findings and recommended corrective actions.
