Iron Control Liquid is designed primarily for:
Matrix Acidizing
Used as an additive in acidizing fluids to control dissolved iron generated during contact between acid and tubulars, scale or formation minerals.
Well Stimulation
Helps minimize secondary iron precipitation during stimulation operations as the injected acid reacts and becomes spent.
Wellbore Cleaning
Suitable for treatment fluids used to remove rust, iron oxide deposits and mineral scale from tubing and associated equipment.
Acid Scale Removal
Can be incorporated into acid descaling formulations where dissolution of iron-containing deposits is expected.
Pickling / Tubing Cleaning
Useful during acid pickling and pre-treatment of tubing where significant quantities of iron may enter the cleaning solution.
Acid Pre-Flush
May be incorporated into selected pre-flush formulations where iron stabilization is required prior to the main acid treatment.
Procedure for effective IRON CONTROL during acidic treatment:
- Expected dissolved iron concentration
- Ferric-to-ferrous iron ratio
- Acid concentration
- Type of acid system
- Formation mineralogy
- Calcium concentration
- Bottom-hole temperature
- Contact time
- Amount of rust and iron scale present
- Shut-in time
- 1-5% by volume of the acid treatment fluid
- may be evaluated as an initial dosage range.
Typical Treatment Dosage Guidelines
| Expected Iron Loading | Suggested Starting Evaluation |
|---|---|
| Low | 1-2% v/v |
| Moderate | 2-3% v/v |
| High | 3-5% v/v |
| Very high / severe iron contamination | Laboratory determination required |

Features and Benefits
- Concentrated liquid iron-control additive
- Helps sequester dissolved ferric and ferrous iron
- Reduces risk of secondary iron precipitation
- Helps minimize formation damage caused by iron deposits
- Helps prevent deposition of ferric hydroxide as acid spends
- Useful where significant rust or iron-containing scale is present
- Helps maintain dissolved iron in the treatment fluid
- Suitable for incorporation into acidizing treatment packages
- Compatible with many conventional oilfield acid systems subject to laboratory testing
- Liquid form provides easy handling and accurate dosing
- Rapidly disperses into aqueous treatment fluids
- Useful during well stimulation and wellbore clean-up
- Can supplement scale-removal and acid-cleaning formulations
FUNCTION OF RXSOL Iron Control Liquid in Oilfield and Acid treatment of wells:
Iron Control Liquid works primarily through sequestration and chelation.
Organic complexes dissolved iron and helps reduce the tendency of ferric iron to form insoluble hydroxide deposits as the treatment acid becomes spent.
Its acidity also assists in maintaining a lower-pH environment during the initial stages of treatment.
RXSOL Iron Control has strong sequestring agent capable of forming complexes with a range of multivalent metal ions. Its inclusion supplements the iron-complexing capability of the formulation and assists in controlling dissolved metallic species.
The combination provides broader metal-ion complexing capability than a simple single-component organic acid treatment and is particularly useful where iron contamination is expected from tubulars, rust, scale or formation minerals.
