diameter. Presently, it is not possible to separate desirable barite particles from undesirable drilled-solid particles that settle at the same rate. The recognized rule of thumb is: A barite particle (SG 4.25) will settle at the same rate as a drilled-solids particle (SG 2.65) having 1½ times the barite particle's diameter.

Barite or weight material sag is a problem of drilling mud and it occurs when weighting material (barite, calcium carbonate, etc) separate from liquid phase and settle down. The method is based in part on continuously measuring fluid density during the first circulation after the fluid has been static after some time.

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.
