Rheological behavior of polymer used in drilling fluid

Drilling fluids perform a role of an interest of age for the good progress of drilling operations. They are exceedingly complex. Their rheological behavior are influenced by the high temperatures and the miscellaneous exterior coercion, where it's necessary to characterize their behavior for a better acquaintance from their rheological properties. Generally, they are adjusted by the addition of polymers and chemical additives in their formulations. The aim of our study is to characterize the rheological behavior of polymer used in drilling fluids with varying numerous factors (high temperatures, different concentrations of polymer).
