It is required to balance 300 sacks of Class G neat cement in 9% open hole by use of a 4%/2-in OD/3.92-in. ID, 13.5lb/ft tubing. The hole depth is 9,000ft and 25bbl of water is to be used as preflush ahead of the cement slurry. Calculate: 1. Total slurry volume, annular volume and tubing volume 2. Height of the balanced plug 3. Volume of water to be used as a spacer behind the cement 4. Volume of mud chase (or displacement volume) 5. Number of strokes required to displace cement to just below the drillpipe shoe, assuming that the pump capacity is 0.15bbl per stroke 6. Volume of cement and number of sacks required if the height of the plug is 500ft. It is required to balance 300 sacks of Class G neat cement in 9% open hole by use of a 4%/2-in OD/3.92-in.
