It is used to control the rheological and filtration properties of the drilling fluid, reducing the intensity of solid phase production during drilling, increasing the lubricating properties of the drilling fluid
The VPRG reagent is packed in polypropylene bags with a polyethylene liner, 20 kg each.
By rail and road transport in covered vehicles.
