The normal method of determining specific gravity is to weigh the specimen dry (DW), then to suspend the specimen in water on a string, and to measure the weight pulling on the string (WW) (specimen weight suspended in water).

Barite is an excellent density control additive; it increases the density well and does not affect fluid rheological properties significantly. The mud retort is a very accurate device to determine specific gravity of solid, however, limited by the amount of sample …

The sizing tests ensure that the barite powder is fine enough to be accepted into liquid. If your drilling grade barite is going to be used for offshore drilling, it needs to be tested for the heavy metals mercury and cadmium. EPA requires that the drilling grade barite has less than 1 mg/kg mercury and less than 3 mg/kg of cadmium.

The ASG of the solids in the drilling fluid can be determined independently with the pressurized mud balance in the same manner as the lowgravity solids and the barite. (See procedure below.) rig-site detemination of specific gravity of drilling solids

Correlations of measured barite sag as functions of fluid shear stress and fluid velocity are shown. These correlations are used to help improve prediction of barite sag occurrence in the field and to help minimize nonproductive time spent dealing with the problem on the rig.
