Calculate the tail, lead and total slurry volume, displacement volume, water and additive requirements for a 13 3/8" casing using the following data: Subsca well with seabed at 450 ft below Rotary Table, 16" hole, TD is at 6000 ft 13 3/8" shoc at 5980 ft, N-80, 72 lb/ft, ID = 12.347 in 20" shoc at 2000 ft, K55, 133 lb/ft, ID = 19.73 in 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. 5" drill pipe, 19.5 lb/ft is used as the running string You are required to base cement volumes on open hole volume plus 30% excess. Lead Slurry: Class G cement +0.3 gals/sk extender + 0.2 gals/sk retarder + 11.35 gals/sk seawater, Yield -1.99 ft/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 ft/sk.
