Iron Control
Iron Control Liquid is a concentrated liquid iron-control additive developed for use in oilfield acidizing, well stimulation, well cleaning and related chemical treatment operations.
The product is based on a synergistic combination of organic active compounds, providing effective complexing and sequestration of dissolved iron. During acidizing operations, iron may be introduced into the treatment fluid through dissolution of rust, corrosion products, mill scale, iron-containing deposits, tubulars and formation minerals.
As the acid becomes spent and the pH of the treatment fluid increases, dissolved ferric iron may form insoluble iron-containing precipitates. These precipitates can contribute to formation plugging, permeability impairment, sludge formation and deposition within the wellbore and production system.
Iron Control Liquid complexes dissolved iron and assists in maintaining it in a soluble or dispersed form during the treatment and subsequent fluid recovery.
The concentrated liquid formulation offers convenient handling, rapid mixing and easy incorporation into acid treatment packages.
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

- 1-5% by volume of the acid treatment fluid
- may be evaluated as an initial dosage range.

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.

Hand protection
Wear suitable gloves. Chemical protection gloves are suitable, which are tested according to EN 374.
For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves. The times are approximate values from
measurements at 22 ° C and permanent contact. Increased temperatures due to heated substances, body heat etc. and a reduction of the effective layer thickness by stretching can lead to a considerable reduction of the breakthrough time. If in doubt, contact manufacturer. At an approx. 1.5 times larger / smaller layer thickness, the respective breakthrough time is doubled / halved. The data apply only to the pure substance. When transferred to substance mixtures, they may only be considered as a guide.
