Polianionic Cellulose -PAC LV (API 13A) DENCELL-PAC LV is used in drilling applications due to its productivity improving characteristics such as film making and water absorbition. It is a good stabilizer and water absorber for drilling mud. It decreases the strength on the drill by its slippery structure and by this way, it increases the productivity. It also helps to eject excavated soils while drilling. DENCELL-PAC LV keeps the mud used in drilling, as homogeneous to avoid excessive water loss during drilling. In this way, it reduces the resistance of soil of different characteristics to drilling machine thus enhances the performance. Because of the lubricity to the mud, it becomes easy to take the drilled soil out. It particularly maintains suspension of the mud which is made of dispersion of clay, barite and bentonite in water in oil industry, and allows for viscosity. With avoidance of water loss through pores and lubricity of DENCELL-PAC LV, it is widely used to take the waste soil out.
