Carbon-blend plugging agent
C‐SEAL industrial carbon blend is a medium‐sized plugging agent used to bridge and seal permeable formations in water‐, oil‐, or synthetic‐base mud systems. C-SEAL reduces differential‐pressure sticking tendencies by bridging and plugging when drilling depleted zones where high differential pressures exist.
C-SEAL can be used to control seepage‐to‐partial‐to‐severe lost circulation zones. C‐SEAL blend is completely inert and does not affect the rheological properties of drilling fluid systems. It reduces torque and drag by increasing lubricity. C‐SEAL material lowers the spurt and total PPT filtrate loss values. C‐SEAL medium‐sized material is an effective and economical blend due to its ability to remain in the entire circulating system if proper solids control equipment is utilized.
