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.

詳細情報
Polyethylene-Polypropylene Glycol
CAS 9003-11-6
グリコール・ポリオール類
Separation aid
EO/PO block copolymer (Pluronic/poloxamer class) with genuine oilfield/industrial use as a low-foam nonionic wetting agent and demulsifier. Low-foam control is specifically needed in flush/displacement so foam does not interfere with pig travel and water displacement during pigging and commissioning.
