GCS PSI PLUS is a Polyamine Shale Inhibitor a high-performance drilling fluid additive used in water-based mud (WBM) systems for advanced shale stabilization and inhibition of clay hydration. Reactive shale formations can absorb water, leading to swelling, dispersion, and wellbore instability. Polyamine-based inhibitors are specifically engineered to provide strong interaction with clay surfaces, ensuring superior stability compared to conventional inhibition systems.

When added to drilling fluids, Polyamine Shale Inhibitor forms a robust protective layer on shale and clay particles, reducing water uptake and preventing structural breakdown. This results in improved cuttings integrity, reduced dispersion, and enhanced wellbore stability. Unlike traditional salts or basic inhibitors, polyamines offer long-lasting performance and are effective even in challenging environments. The product is compatible with water-based mud systems and performs reliably across offshore, extended reach drilling (ERD), and high-pressure high-temperature (HPHT) conditions.
