MIC-220
Made in USA
MIC-220 is an iron sulfide dissolver and a general well-bore cleaner. MIC-220 has a storage life of one year. Keep container closed when not in use. As with all industrial chemicals, safety glasses, gloves and aprons are recommended for use when handling this product.
MIC-220 is an effective iron sulfide remover. Below is a comparison with widely used FeS dissolvers:
| Property | 5% HCl + DTPA | Acrolein | THPS + NH4CL | Inhibited 7.5% HCl | MIC-220 (pH=6) |
| Kinetics | Excellent | Fair | Fair | Excellent | Fair |
|---|---|---|---|---|---|
| Corrosivity | Poor | Low | Moderate | Poor | Moderate |
| Secondary Deposition | Poor | Low | Low | Poor | Low |
| H2S Evolution | High Risk | No Risk | High Risk | High Risk | No Risk |
| Handling | High Risk (Corrosive) | High Risk (Toxic, Explosive) | High Risk (Toxic) | High Risk (Corrosive) | Low Risk |
| CaCO3 Reaction | Good | Poor | Poor | Good | Good |
Metal Chelation Capacity
MIC-220 will chelate iron and prevent FeS deposition. A table of metal chelation capacity is shown below:
| Metal Iron | Parts MIC-220 per Part Metal |
|---|---|
| Ca | 25 |
| Mg | 40 |
| Fe | 20 |
| Cu | 15 |
| Mn | 15 |
Product Application
MIC-220 is generally added in concentrations from 1.0% to 10.0%. The product can be used as a 50% solution for severe accumulations or diluted with water as needed. To prevent FeS deposition, use 1 gallon/1000 bbls of water for every 1 ppm of iron (Fe). If Ca or Mg are present use 5 to 10 gallons/1000 bbls of water for every 1 ppm of iron (Fe). As always, run compatibility tests on any formulations.
