Product Description
Summary
Graphite Powder is a coarse sized plugging agent used to bridge and seal permeable formations in water, oil or synthetic base mud systems. When drilling depleted zones where high differentia1 pressures exist, the bridging and plugging capabilities of Graphite powder reduce differential pressure sticking tendencies. Lt can be used to control seepage in partial to severe lost circulation zones. Graphite Powder is completely inert and does not affect rheological properties. Graphite Powder reduces torque and drag by increasing the lubricity. Graphite Powder lowers the spurt and tota1 filtrate loss values in PPT and sanded laboratory studies.

3. Application
Graphite Powder is designed to bridge and seal permeable formations., reducing the possibility of differential sticking, controlling lost circulation and increasing lubricity.
Graphite Powder can be used in combination with other lost circulation materials to control partial to severe losses. Very high permeability formations such as fractured carbonates and conglomerate zones may require additional spots in conjunction with a variety of lost circulation materials of varied particle size distribution. Graphite Powder may require additional wetting agent when used in an oil or synthetic base mud system.
4. Advantage
Effective bridging and sealing agent for a wide range of formations and severity of losses. Controls seepage losses, thereby reducing the possibility of differential sticking.
Increases lubricity to reduce torque and draft in all mud system.
One sack product with no other additive requirements and easily mixed an dispersed into the system.
Temperature stable to more than 500*F(260*C)
5. Toxicity and Handling
Graphite Powder should be handled as an industrial chemical, wearing protective equipment and observing the precaution as described on the MSDS.
