Oil & Gas Drilling
| Application | Calcium Carbonate (CaCO₃) | Bentonite |
|---|---|---|
| Drilling Fluids | Acts as a bridging and weighting agent to stabilize the wellbore. | Provides viscosity, suspension, and filtration control. |
| Cementing & Wellbore Stability | Improves density, strength, and seals microfractures. | Forms a gel layer that prevents fluid migration. |
| Lost Circulation & Mud Conditioning | Reduces leakage and improves mud density. | Swells to seal porous formations and maintain rheology. |
