Amount of Cement to be Left on Casing

Amount of Cement to be Left in Casing formula

\( AC \;=\; ( C_l - D ) \; C_c  \)     (Amount of Cement to be Left in Casing)

\( C_l \;=\; ( AC \;/\; C_c ) + D  \)

\( D \;=\;  C_l - ( AC \;/\; C_c )  \)

\( C_c \;=\;  AC \;/\; ( C_l - D )  \)

Symbol English Metric
\( AC \) = Amount of Cement left in Casing \(ft^3\) -
\( C_l \) = Casing Length \(ft\) -
\( D \) = Setting Depth of Cementing Tool \(ft\) -
\( C_c \) = Casing Capacity \(ft^3\;/\;ft\) -
