Annular Capacity (Volume)
The values in Table 20 are given as annular capacity in barrels per linear foot (bbl/ft). API tubing sizes are given along the top of the table, and casing and plain end liner dimensions are the values in the first three columns on the left. The capacity is given in the cell that represents the intersection of the tubing column and the casing row. The table is large, so a thumbnail image is shown below.
