Description
DDC Mica is used to control lost circulation in water and oil base drilling fluids without any negative effects on drilling fluid properties.DDC Mica is available in three grades: Fine ( F ), Medium ( M ) and Coarse ( C ) .
The fine grade of micacan be circulated through a 20 mesh screen. Larger grades will be removed from the system unless the solids control equipment is by passed.
