FORMATION SEAL

Formation Seal is made available in fine (F), medium (M) and coarse (C) grades.

Formation Seal (F/M/C) lost circulation material is a natural occurring cellulose material that can be used effectively in spot pills, sweeps and maintenance treatments with minimal adverse effect on rheology and filtration control properties. The cellulosic material helps decrease the permeability of the wall-cake in all drilling fluid types with no chemical additives.
