Calculate the tail, lead and total slurry volume, displacement volume, water and additive requirements, differential hydrostatic pressure before releasing top plug, hydrostatic pressure in the annuls, and total job time for a 13 3/8" casing using the following data: - 20" (ID = 19.73 in.) shoe at 2000 ft - 16" hole to a depth of 6000 ft - 13 3/8" (ID = 12.347 in.) shoe at 5980 ft - TOC to be 500 ft inside 20" casing shoe - Tail slurry to extend 500 ft above the 13 3/8" shoe - The shoe track consists of 1 joint (40 ft). - 30% excess and 11 ppg mud. - Mixing and pumping rates are 10 bbl/min - Lead Slurry: Class G cement +0.3 gals/sk extender +0.2 gals/sk retarder + 11.35 gals/sk seawater, Yield = 1.99 ft3/sk, Density = 13.0 ppg - Tail slurry: Class G cement +0.05 gals/sk retarder +0.05 gals/sk dispersant + 4.8gals/sk freshwater, Yield = 1.13 ft3/sk, Density = 16.00 ppg - Calculate the tail, lead and total slurry volume, displacement volume, water and additive requirements, differential hydrostatic pressure before releasing top plug, hydrostatic pressure in the annuls, and total job time for a 13 3/8" casing using the following data: - 20" (ID = 19.73 in.) shoe at 2000 ft - 16" hole to a depth of 6000 ft - 13 3/8" (ID = 12.347 in.) shoe at 5980 ft - TOC to be 500 ft inside 20" casing shoe - Tail slurry to extend 500 ft above the 13 3/8" shoe - The shoe track consists of 1 joint (40 ft). - 30% excess and 11 ppg mud. - Mixing and pumping rates are 10 bbl/min - Lead Slurry: Class G cement +0.3 gals/sk extender +0.2 gals/sk retarder + 11.35 gals/sk seawater, Yield = 1.99 ft3/sk, Density = 13.0 ppg - Tail slurry: Class G cement +0.05 gals/sk retarder +0.05 gals/sk dispersant + 4.8gals/sk freshwater, Yield = 1.13 ft3/sk, Density = 16.00 ppg
