Primary Applications in Oil & Gas

• Iron Control & Sequestration:
  • Acts as a powerful chelating agent to bind soluble iron (Fe²⁺/Fe³⁺) during well stimulation and acidizing.
  • Prevents iron from precipitating as iron hydroxide, which can clog the formation and reduce well permeability.
  • Reduces the risk of iron-induced crosslinking in polymers like xanthan gum, maintaining fluid viscosity.
• Well Stimulation & Acidizing:
  • Used as a “mild” alternative to hydrochloric acid (HCl) for dissolving mineral scales like calcium carbonate and iron oxides.
  • Stabilizes pH levels in acid blends to improve the efficiency of treatments.
  • Protects expensive well tubulars and equipment from corrosion during acid treatments.
• Drilling Fluid Management:
  • Cement Contamination: Effectively reduces the high alkalinity (pH) caused by cement contamination during drilling operations.
  • Calcium Removal: Precipitates and removes calcium ions from water-based drilling muds.
  • Polymer Stabilization: Prevents the formation of “fish-eyes” (undissolved lumps) when mixing polymers.
• Scale Inhibition & Cleanup:
  • Dissolves and prevents scale deposits in pipelines and wellbores, ensuring smooth fluid flow.
  • Used in post-drilling cleanup to remove debris and prepare the well for production.
