BAROFIBRE SUPERFINE, finely ground cellulosic material, is designed to effectively seal the borehole wall in sands.
To stop the loss of drilling fluid, the voids must be plugged so a filter cake can be formed on or in the porous rock.
BAROFIBRE SUPERFINE can be used in all types of water-based and oil-based drilling fluids.
*Applications/Function: Reduce wallcake permeability and seepage loss, Seal and bridge sands and microfractures, Lubricate the wellbore by creating a more lubricious filter cake.
*Advantages: Is compatible with most water-based and oil-based muds, Will not plug drilling equipment, Is biodegradable and nontoxic. |
