Scale Inhibitors for Oilfield & Injection Systems

Prevent carbonate, sulfate, and silica scale in injection and production systems
Why It Matters
Prevent carbonate, sulfate, and silica scale in injection and production systems
Solution Approach

Prevent carbonate, sulfate, and silica scale in injection and production systems 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 rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (5)
Hydroxyethylidene Diphosphonic Acid
CAS 2809-21-4
Phosphate Esters & Derivatives
Common phosphonate antiscalant
Threshold inhibitor: chelates Ca2+/Mg2+ sub-stoichiometrically and distorts the growing crystal lattice so carbonate scale can't nucleate
Melting Point: 198-199   Boiling Point: 578.8   Solubility: 1.15e+01 g/L
Full Details
Amino Trimethylene Phosphonic Acid
CAS 6419-19-8
Phosphate Esters & Derivatives
High-performance threshold inhibitor
High-performance phosphonate that sequesters scaling cations and disrupts crystal growth at sub-ppm dose
Melting Point: 210 - 215 °C   Solubility: 1000 mg/mL at 25 °C   Vapor Pressure: 0.0000001
Full Details
HPAA (2-Hydroxyphosphonoacetic Acid)
CAS 23783-26-8
Phosphate Esters & Derivatives
Chelation / Sequestration

Physical Description: Brown liquid. Slight acrid odor
Full Details
Polyepoxysuccinic Acid (PESA)
CAS 51274-37-4
Phosphate Esters & Derivatives
Chelation / Sequestration
