G-Seal™ sized graphite bridging agent is a coarse-sized plugging agent that is chemically inert and thermally stable. It lowers the potential for lost circulation and reduces torque and drag in many drilling applications.

When drilling depleted zones are exposed to high differential pressures, the bridging and plugging capabilities of G-Seal agent can reduce the potential for stuck pipe. G-Seal agent is chemically inert and thermally stable and will not affect rheological properties when used at recommended concentrations. It lowers the potential for lost circulation and reduces torque and drag in many drilling applications.

G-Seal agent is used in water-, oil- or synthetic-based drilling fluids to bridge and seal permeable and fractured formations. G-Seal agent can be used in any type of drilling fluid to bridge and seal permeable and fractured formations, thus controlling lost circulation and reducing the possibility of differential sticking. G-Seal agent decreases the coefficient of friction (COF) of drilling fluids.

• Reduces the potential for stuck pipe
• Controls seepage losses, minimizing the risk of differential sticking
• Reduces the COF to decrease torque and drag in all mud systems
• Bridges and seals a wide range of formations, effectively addressing various levels of loss severity
