How many sacks of barite are necessary to increase the densi

How many sacks of barite are necessary to increase the density of 1000 bbl of mud from 11 to 13.5 lbm/gal? What is the volume of water added?

Sacks of Barite per 100 bbl of mud = 1470 x (W2 – W1) ÷ (35 – W2)

Where; W1 = current mud weight

W2 = new mud weight

Sacks of Barite per 100 bbl of mud = 1470 x (13.5 – 11.0) ÷ (35 – 13.5)

Sacks of Barite per 100 bbl of mud = 170.93 sacks

So, sacks of barite needed for 1000 bbl of mud= 1709.3 sacks
