Oilfield Scale Inhibitor (BaSO₄ / CaCO₃)
CAS Number: N/A (blend)
High-temperature, high-pressure compatible scale inhibitor formulated for oilfield injection water and produced water systems. Effective against CaCO₃, BaSO₄, and SrSO₄ precipitation in wellbores, tubing, and subsurface injection equipment via continuous injection or downhole squeeze treatment.
Technical Specifications
| dosage | 5–50 mg/L injection water |
| packaging | 200 kg drum or IBC |
| appearance | Clear to amber liquid |
| compatibility | Compatible with typical oilfield brines and corrosion inhibitors |
| scale control | CaCO₃, BaSO₄, SrSO₄ |
| temperature range | 50–150°C |
| application method | Continuous injection or squeeze treatment |
Applications
- Downhole squeeze treatment for wellbore scale prevention
- Continuous injection into injection water lines
- Subsea and offshore production flowlines
- Waterflood injection systems targeting secondary oil recovery
- Produced water handling and reinjection facilities
- High-temperature geothermal water systems with scaling potential
Key Features
- Effective against BaSO₄ and SrSO₄, the most difficult oilfield scales to remove mechanically or chemically after deposition
- Squeeze-compatible formulation adsorbs onto formation rock and desorbs slowly for extended protection (months per treatment)
- Maintains inhibitory performance at reservoir temperatures up to 150°C where many inhibitors degrade
- Low dosage (5–50 mg/L) reduces chemical cost in high-volume injection water applications
- Broad compatibility with oilfield brines of varying TDS, Ca²⁺, Ba²⁺, and SO₄²⁻ concentrations
