For example, if the mud weight of a mud cleaner screen discard weighs 18.0 ppg, the low gravity solids concentration would be about 42% volume if the solids concentration is 58% volume. Barite would be 16% volume. Low gravity solids concentration would be about 48% volume if the discard total solids concentration is 60% volume.

Baryte

Worldwide, 69–77% of baryte is used as a weighting agent for drilling fluids in oil and gas exploration to suppress high formation pressures and prevent blowouts. As a well is drilled, the bit passes through various formations, each with different characteristics. The deeper the hole, the more baryte is needed as a percentage of the total mud mix. An additional benefit of baryte is that it is non-magnetic and thus does not interfere with magnetic measurements taken in the borehole, either during logging-while-drillingor in

What is Barite? Industrial Minerals Association North

Jul 22, 2019 Barite’s high density and chemical inertness make it an ideal mineral for many applications. The chemical formula for barite is BaSO4. It has a high specific gravity of 4.50 g/cm3.

Barite (BARIUM)

Barite (spelled baryte in British publications) was named from the Greek word baros which means weighty, a reference to its unusually high specific gravity. (Specific gravity is a mineralogist’s measure of the density of a mineral; this is done by comparing the weight of the mineral to the weight of an equal volume of water.)

Specific Gravity Drilling Fluids Rig Worker

Jan 06, 2021 For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water. As an example, a 17.5 lb/gal mud has a specific gravity of 2.1.
