Abstract:
This study aims at the assessment of the effect of Polyanionic Cellulose Polymer (PAC-LV) into water base drilling fluids Properties. Laboratory investigations of physical properties of raw material (clay) show that the clay is near to class Ca Bentonite. Adding PAC-LV increases viscosity and decreases filter loss. Drilling fluids need huge amount of PAC-LV to meet American Petroleum Institute Standards (API). The study concludes that the PAC-LV is an expensive drilling fluids properties improver, not recommended to be used.
