Filtration Control Agent
Product Description
VIS D is a new generation HIGHLY DISPERSIVE high quality polymer used for viscosity and water loss control in most water based drilling fluid systems. VIS D will not fisheye and has been designed to disperse rapidly into any make up water even under the poorest conditions. The mixing efficiencies of VIS D reduces wastage and promotes lower mud costs and total hole costs.
