Description
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
Applications
Main function of Graphite is to reduce friction while drilling with water-based drilling fluids and increase rate of penetration. Besides that, possibility of mechanical stuck or differential stuck is highly decreased while using Graphite. Adding Graphite in high-deviated and horizontal wells is highly recommended. Graphite may be used in depleted zones, to reduce seepage to partial losses.
Safety tips
FIRST AID MEASURES
Eye Contact:
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.
Skin Contact:
Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops.
Inhalation:
If dust is inhaled, remove from contaminated area.
- Encourage patient to blow nose to ensure clear passage of breathing.
Ingestion:
- Immediately give a glass of water.
- First aid is not generally required. If in doubt, contact a Poisons Information Centre or a doctor
