Calcium Carbonate Flakes – Acid‑Soluble LCM for Severe Loss Zones in Germany

Filtron Envirotech (India) is a leading manufacturer, exporter and supplier of oil drilling chemicals and specialty calcium carbonate flakes. Based in Delhi, our facility produces high‑purity calcium carbonate flakes that serve as an effective Lost Circulation Material (LCM) for bridging fractures, vugs, and highly permeable zones. Our flakes are exported worldwide to drilling operators facing severe fluid loss challenges.

Calcium Carbonate Flakes are engineered to control severe fluid loss in porous, fractured, or vugular formations. Their flat, plate‑like shape creates an immediate mechanical bridge across large openings, stopping fluid escape while allowing further sealing by finer LCM particles. These flakes are widely used in oil, gas, and geothermal drilling due to their acid solubility, formation compatibility, and cost‑efficiency. After drilling, they dissolve easily in acid, leaving no damage to the reservoir.

Our calcium carbonate flakes are available in multiple particle size grades to match specific fracture widths and circulation loss rates. They are fully acid‑soluble (>95% in 15% HCl), allowing simple post‑drilling removal without harming the formation. Compatible with both water‑based and oil‑based drilling fluids, these flakes maintain wellbore integrity, reduce non‑productive time, and protect downhole equipment in onshore, offshore, and HPHT applications.
