Dilution of a mud system
Input(s)
\(\mathrm{V}_{\mathrm{m}}\): Mud in Circulation System (bbl)
\(\mathrm{F}_{\mathrm{ct}}\): Per cent of Low Gravity Solids in System (per cent)
\(\mathrm{F}_{\text {cop }}\): Per cent of Total Optimumlow Gravity Solids (per cent)
\(\mathrm{F}_{\mathrm{ca}}\): Per cent of Low Gravity Solids (Bentonite and or Chemicals Added) (per cent)
Output(s)
\(\mathrm{V}_{\mathrm{wm}}\): Dilution Water or Mud Required (bbl)
Formula(s)
\[
\mathrm{V}_{\mathrm{wm}}=\frac{\mathrm{V}_{\mathrm{m}} *\left(\mathrm{~F}_{\mathrm{ct}}-\mathrm{F}_{\mathrm{cop}}\right)}{\mathrm{F}_{\mathrm{cop}}-\mathrm{F}_{\mathrm{ca}}}
\]
