Barite (BARIUM)
BARITE (Barium Sulfate) with the chemical formula of BaSO 4. is used as a weighting agent in all types of drilling fluids. Application of barite • Increase mud density up to 21 lb/gal (2.5 g/cm3) • Control formation pressure • Stabilize the borehole • Prepare solids-laden plugs for well control application Advantages

Comminution of solids caused by kinetic energy of high …
The microlevel kinetic energy is dissipated by fluid viscosity in the eddies of turbulent flow, or by the energy, Γ, of interface fracture or subsequent frictional slip. However, unlike an eddy, the local shear strain motion cannot continue indefinitely. ... However, if decreases while remaining in the comminution range according to Eq. 7, ...
