Slug calculation
Barrels of slug required for a desired length of dry pipe
Desired length of dry pipe
Drill pipe capacity
Current mud weight
Slug weight
Hydrostatic pressure required to give desired drop inside drill pipe
psi
Difference in pressure gradient between slug and current mud weight
psi/ft
Length of slug in drill pipe
ft
Slug volume
bbl
Weight of slug required for a desired length of dry pipe with a set volume of slug
