HANDLING & STORAGE
EOS ZVI is shipped as concentrated oil and iron slurry that is diluted with water in the field to prepare a solution for easy injection. EOS ZVI can be distributed with commonly available pumps. Dilution ratios for EOS ZVI typically range from 1:1 to 5:1 (water: EOS ZVI) depending on site conditions. EOS ZVI injections should be followed with additional chase water to maximize distribution of EOS ZVI into the formation.
EOS ZVI as shipped, has a shelf-life of ≥ 2 years dependng on storage conditions.
