How much barite is required to increase the density of 300 bbls of mud from 4 ppg to 15 ppg. How much 12 ppg mud is needed to prepare exactly 250 bbls of 14 ppg mud? What volume of water will be necessary to reduce the density of 1200 bbls of 15.2 ppg mud to 13.5 ppg? Calculate how much water and barite must be mixed to make exactly 500 bbl of 14 ppg mud? Calculate how much oil, water and barite are required to make exactly 300 bbl of 15 ppg oil mud with 80/20 oil/water ratio. Calculate how much oil will have to be added to change the oil/water ratio of 100 bbl of 80/20 oil mud to 90/10. If the same 80/20 mud is to be changed to 75/25 oil water ratio, calculate how much water will have to be added Retort Analysis: Oil : 64 %, Water 16 % and Solids: 20 %
