Polyamine Shale Inhibitor | Polyamine Shale Stabilizer | Clay Hydration Suppressant

PETRA PSI is a high-performance liquid polyamine shale inhibitor designed for water-based mud systems, drill-in fluids, and polymer-based drilling operations. It effectively preventss shale and clay hydration without negatively impacting viscosity or filtration properties. PETRA PSI enhances wellbore stability, reduces bit balling, improves lubricity, and increases Rate of Penetration (ROP).

What is a Polyamine Shale Inhibitor?

A Polyamine Shale Inhibitor is a cationic polymer used to control clay swelling and shale instability in reactive formations. It suppresses clay hydration, minimizes cuttings dispersion, and maintains wellbore integrity during drilling operations.

Key features include:

• Prevents shale and clay hydration
• Reduces bit balling and accretion
• Improves wellbore stability
• Enhances drilling performance and ROP
• Compatible with common drilling contaminants

Applications of PETRA PSI

• Differentially Stuck Pipe Removal Spotted to penetrate mud cake and release stuck pipe.
• Stuck Pipe Prevention Added to drilling fluid to reduce sticking tendency.
• Torque & Drag Reduction Improves lubricity for smoother drilling operations.
• HPHT & Complex Wells Performs reliably in high-pressure, high-temperature wells.
• WBM & OBM Systems Compatible with water-based and oil-based mud systems.
