Enter the length of the slug pipe (ft) and the drill pipe capacity (bbl/ft) into the Slug Volume Calculator. The calculator will evaluate the Slug Volume. 

Slug Volume Formula

The following two example problems outline the steps and information needed to calculate the Slug Volume.

SLG = LS * C

Variables:

  • SLG is the Slug Volume (bbl)
  • LS is the length of the slug pipe (ft) 
  • C is the drill pipe capacity (bbl/ft) 

How to Calculate Slug Volume?

The following steps outline how to calculate the Slug Volume.


  1. First, determine the length of the slug pipe (ft). 
  2. Next, determine the drill pipe capacity (bbl/ft). 
  3. Next, gather the formula from above = SLG = LS * C.
  4. Finally, calculate the Slug Volume.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

length of the slug pipe (ft) = 40

drill pipe capacity (bbl/ft) = 3.25

SLG = LS * C = ?
