Frequently Asked Questions — PHPA Oilfield Grade
Is your PHPA suitable for FLOPAAM 3630S duty?
Our PHPA is in the same very high molecular weight, partially hydrolysed anionic range used for polymer flooding. Whether it suits your specific flood depends on your brine chemistry and reservoir temperature — divalent hardness and temperature govern selection more than any headline figure. We are not claiming our product is identical to FLOPAAM 3630S or that it will perform identically in your flood. Send us your brine analysis and reservoir temperature and we will ship a sample for your own core-flood and viscosity-retention comparison.
What salinity environments is your PHPA suitable for?
Our standard PHPA is designed for moderate salinity applications. For high-salinity or hard-brine applications, contact us with your full brine ion analysis including calcium and magnesium levels and we will confirm which grade applies and provide viscosity data in your synthetic brine before you commit.
What is the minimum order for EOR projects?
Pilot quantities start at 5 MT. For full-scale flooding we write 50+ MT/month supply agreements with fixed specification windows and batch-level COA, since polymer consistency matters more than headline price once injection starts. Tell us the pilot volume and timeline and we will quote both the trial and the follow-on contract.
