ソリューションアプローチ

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
System Assessment
Characterize operating conditions — fluid composition, temperature, pressure, flow, and H2S/CO2/water cut — and benchmark current treatment performance.
2
Chemistry Selection
Match scale and corrosion inhibitors, biocides, or demulsifiers to the operating envelope, factoring compatibility, regulatory constraints, and downstream impacts.
3
Field Trial & Dosing
Determine treat rates through bottle and field trials, and configure continuous or batch delivery and packaging (drums, totes, ISO tanks) to logistics.
4
Monitoring & Adjustment
Track corrosion coupon/ER rates, residual inhibitor, and separator and water-quality performance, adjusting chemistry and dose as wells change.
