 |
BAROFIBRE, fibrous cellulosic material, is designed to effectively seal the borehole wall in sands and fractured zones.
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 can be used in all types of water-based and oil-based drilling fluids.
BAROFIBRE is available in two grades: regular and coarse.
*Applications/Functions: Reduce wallcake permeability and seepage loss, Seal and bridge depleted sands and microfractures.
*Advantages: Is compatible with most water-based and oil-based muds, Has no adverse effects on rheological and filtration control properties of drilling fluids, Will not plug drilling equipment, Is biodegradable and nontoxic |
