PetroFix Well Injection Planning

When storing the PetroFix material prior to application, it is important to prevent it from freezing or from prolonged exposure to temperatures above 95°F.

• Storage requirements for freezing or hot weather
• Safety Data Sheets (SDS)

The key to a successful well application is to have properly screened wells where the screen is confined across your treatment zones only. We recommend you use a water tight injection attachment to the top of your well and apply PetroFix under low pressure (commonly 20-30 psi). Optimally, you can construct your monitoring wells with a male NPT thread so receive a female threaded injection hose adapter. If you are using existing injection wells you can use ratchet straps that prevents gluing any attachments fittings to a well. Please consult with your injection contractor for their recommended method to inject into your monitoring well(s). Flushing by gravity feed into wells is not recommended. When complete some practitioners opt for a clear water post-injection flush at the end of their injection activities. If your site has a high number of wells we recommend that you install a single well and do a pilot injection prior to full-scale implementation to verify the ability to inject PetroFix at the specified volumes.

Please note, PetroFix takes up to a few months to fully attach to soils. If PetroFix is >100 mg/L in concentration (difficult to see through a 40 ml VOA), it is recommended groundwater not be sampled. Each PetroFix shipment comes with one (1) a colorimetric field test kit taped to the top of a tote or drum to help assess field concentrations. For additional information, please review the “Groundwater Sampling Guidance Document”.
