1️⃣ Bentonite

🌊 Forms a gel-like suspension

🌀 Improves viscosity and carrying capacity

🛡️ Stabilizes the wellbore and prevents collapse

💧 Enhances lubrication and sealing

2️⃣ Barite

⚖️ Increases mud density

🔒 Balances formation pressure

🚫 Prevents blowouts

💨 Does not affect viscosity, mainly adds weight

Bentonite and Barite grinding mill

💡 Summary:

Bentonite = the "skeleton & viscosity" of the mud

Barite = the “weight” to control formation pressure

Often used together for optimal drilling performance
