Quick calculators for drilling fluid and powder work. Free to use, no sign-up.
Barite requirement calculator
Estimate how much barite you need to raise the density of a drilling fluid, and how much the volume will grow.
The calculation is a standard mass balance and assumes no solids are removed and no water is added. Use it for planning, and confirm on site.
Mesh to micron converter
Standard sieve sizes (ASTM E11) with their opening in microns. Type a mesh number or a size in microns to find the nearest sieve.
