Oflex – 50 (Polyamine Shale Inhibitor)

Oflex-50 - Polyamine shale inhibitor is a high-performance, cationic water-soluble polymer used in water-based drilling fluids (WBM) to control shale hydration, swelling, and dispersion. It enhances wellbore stability by forming a protective layer on clay surfaces and minimizing water intrusion.

Key Features:

Effectively prevents shale swelling and dispersion.
Improves wellbore stability and cuttings integrity.
Reduces bit balling and drilling issues.
Compatible with most WBM systems.

Typical Properties:

Appearance: Clear to pale yellow liquid
pH (1% solution): 7 – 10
Density: 1.00 – 1.10 g/cm³
Active Content: 30% – 60%
Solubility: Fully water-soluble
Amine value 200 to 500

Application:

Widely used in oil & gas drilling, especially in shale and clay-rich formations, including horizontal and directional drilling operations.

Dosage:

Recommended dosage ranges from 0.5% to 3.0% v/v, depending on formation conditions and mud system design.

Advantages:

Environmentally safer alternative to KCl systems
Low toxicity and biodegradable grades available
Cost-effective solution for drilling stability
Performs well under high-temperature conditions

Packaging & Storage:

Available in 50 kg / 200 kg HDPE drums and IBC tanks. Store in a cool, dry place. Shelf life: 12–24 months.
