Impact of barite and ilmenite mixture on enhancing the ...

The rheological properties of barite/ilmenite are similar to or better than that of barite and therefore could be used in place of barite in drilling fluids formulations. At mud density value of 8.65 Ib/100 ft 2 and normal temperature, the plastic viscosity of barite/ilmenite mixture was recorded at 5.0 cp and achieved the same value for barite.
