Frequently Asked Questions — PHPA Oilfield Grade
Is your PHPA a direct substitute for FLOPAAM 3630S?
Yes. Our PHPA provides equivalent viscosity (30–80 mPa·s at 0.1%), same MW range (15–25M), and same hydrolysis degree (25–35%). We have field data from Daqing and Shengli oilfields confirming interchangeable performance.
What salinity can it tolerate?
Standard grade works up to 10,000 ppm TDS. Our salt-tolerant formulation handles 30,000+ ppm TDS and is suitable for Middle East and offshore reservoirs.
What is the minimum order for EOR projects?
Pilot: 5 MT minimum. Full-scale: 50+ MT/month supply agreements available. We supply Daqing, Shengli, ONGC (India), and ADNOC projects.
