Abstract

This paper evaluates Nigerian Waxy Crude Oil using Bingham Plastic model and Power Law model. Laboratory measurements on rheology were carried out on the sample as per API standard at temperatures of 30oC and 50oC. The obtained data of shear rate and shear stress were regressed and plotted. The Bingham Plastic model gave the values of yield stress and the regression coefficient as 0.673lbs/100ft2 and 0.9996 at the temperatures of 30oC; 0.622lbs/100ft2 and 0.9986 at the temperature of 50oC. Also, the Power Law model gave zero yield stress and regression coefficient of 0.9737 and 0.9884 at both temperatures. From the result, Nigerian Waxy Crude Oil is more adequately predicted by Bingham Plastic model because of the exhibition of Plastic behavior of a higher regression coefficient
