Drilling grade barite density testing is performed in accordance with the American Petroleum Institute (API) standard 13A. The API specification for density of drilling grade barite is a minimum of 4.20 g/ml. A purity test, called "water-soluble alkaline earth metals, as calcium" is also performed on barite during API 13A testing.
We characterized the barite sag of a liquid column under static condition using light-scattering (LS) measurements, hydrostatic pressure measurements, and gamma densitometry.
Students should be able to easily identify barite using the "heft test" (placing Specimen "A" in their right hand and Specimen "B" in their left hand and "hefting" the specimens to determine which one is heaviest). Students in third or fourth …
Barite was named after the Greek word "Barys" meaning "heavy". This heavy nature can be explained by its exceptionally Specific Gravity of 4.5, a number that's very high for a nonmetallic mineral. The chemical composition of this sedimentary rock is mostly made up by Barium Sulfate. Barite is a mineral that comes in a variety of ...
Dynamic Barite Sag Measurements. There have been numerous attempts to measure dynamic barite sag, both in the lab and the field, under HTHP conditions. For the purposes of this …

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.) Sources
Barite is added to increase the mud's specific gravity, which maintains the hydrostatic equilibrium, preventing gas, oil or saltwater from entering from high-pressure zones. Barite intended for this market must meet specifications set by the American Petroleum Institute, which set limits on size, specific gravity and soluble alkaline salt ...
The issue of barite sagging is well-known in the petroleum industry. Several techniques have been developed to evaluate the sagging tendency of mud. However, barite sag prediction has been a daunting task due to the poor correlation between sagging and predictive indicators (Hemphill and Rojas, 2004). Over the years, many approaches have been ...

Weighting agents are mixed with the drilling mud to provide the high density required to control high-pressure high-temperature (HPHT) wells throughout the drilling operation. Solids sag occurs when the weighting agent separates from the liquid phase and settles down, causing variations in the drilling fluid density.
