IRONFIXTM is a game-changing Engineered BioFluid (EBFTM) that targets iron control in contaminated reservoir formation waters. The unique biopolymer-based chemistry reacts with dissolved ferrous iron in formation, flow back, and produced waters to maintain reduced iron in solution at the molecular level, preventing ferric iron phases from precipitating in the wellbore. IRONFIXTM is compatible with the full range of Integrity Bio-Chem completion fluid additives, allowing operators and pumping service companies to target specific zones enriched in dissolved iron.
Reservoirs with diverse mineral assemblages and dynamic pH conditions often create anomalies in formation fluid chemistries, with one of the most perilous problems being iron oxidation. IRONFIXTM is a cost-effective and dual-functioning solution for this problem, formulated as an iron chelator and buffering solution for complex and variable waters intersected during drilling and completion. The unique biopolymer chelation agent is also formulated to form complexes with metals, including alkali metal cations, enhancing chelation efficiency.
IRONFIXTM pre-empts the oxidation of dissolved ferrous iron due to sudden changes in dissolved oxygen content and pH of the completion fluids. The chelates formed are readily flowable, ensuring they can be easily swept from the well in the flow back. IRONFIXTM inhibits ferric iron precipitation in the nanoporous rock network and on perforated casings, enabling targeted application for specific problematic zones. The recommended usage rate is 1.0 gallon per 1000 (GPT) per 100 mg/L of dissolved iron in the water. IRONFIXTM is the go-to solution for iron control in the oilfield, offering iron chelation, metal complexes, targeted application, and dissolved flow back in one innovative and highly effective product.
