				HY-SEAL, shredded cellulosic fiber, can be used to reduce lost circulation in waterbased luids.  When combined with lost circulation materials made of coarser fibers, HY-SEAL rapidly bridges between the coarser fibers and speeds formation of the seal when larger openings in the formation are taking fluid. *Applications/Functions: HY-SEAL can be used to reduce lost circulation in porous sands and fine gravels. *Advantages: Disperses rapidly, Does not separate out of or float in clear-water fluids, Quickly seals porous formations |
