G‐SEAL

Graphite plugging agent for all mud systems

G‐SEAL graphite is a coarse‐sized plugging agent used to bridge and seal permeable formations in water, oil or synthetic‐based drilling fluids. When drilling depleted zones where high differential pressures exist, the bridging and plugging capabilities of G‐SEAL additive reduce differential‐pressure sticking tendencies. It can be used to control seepage in partial‐to‐ severe lost‐circulation zones.

G‐SEAL additive is completely inert and does not affect rheological properties. It reduces torque and drag by increasing the lubricity and lowers the spurt and total filtrate loss values in Permeability Plugging Test (PPT) and sandbed laboratory studies.

When drilling depleted zones where high differential pressures exist, the bridging and plugging capabilities of G‐SEAL additive reduce differential‐pressure sticking tendencies. It can be used to control seepage in partial‐to‐ severe lost‐circulation zones. G-SEAL is designed specially to bridge and seal permeable formations, reducing the possibility of differential sticking, controlling lost circulation and increasing lubricity.
