Graphite is a high-quality grade of mechanical lubricating agent which is widely used in drilling fluids to maximize lubricity properties. Graphite forms a thin film on BHA, bit and drill pipes in order to minimize torque and drag and reduce possibility of stuck. Graphite is chemically inert and may be applied in both water-based and oil-based mud systems.
Advantages
- Compatible with different types of water-based drilling fluids
- Reduce friction in slide drilling
- Reduce possibility of differential sticking
- Chemically stable in downhole temperature and pressure
- Increase rate of penetration
- Effective bridging and sealing agent in thief zones
- Chemically Inert
- Reduce unwanted torque while drilling
- Help to drill a smooth well path
