Study on Physical properties of Yield point in Fluid Polymer at Various Temperatures and pressures

The aim of this study is to predict changes Yield point of polymer drilling fluid In different temperature and pressure in the during drilling process. In this study, used kind of poly anionic cellulose and starch potato. we studied Yield point at pressures of 411 PSI , 711PSI, 011PSI and constant temperature (011 F ° ) and effect temperature at atmospheric pressure. We examined Yield point at different times at constant pressure. We can concludethat the effect of temperature on the yield point is steady but effect temperature with change pressure is not steady.The effect pressure on yield point in low temperature is stronger
