Drill pipe or drill collar displacement and weight
Input(s)
ID: Inner Diameter (in.)
OD: Outer Diameter (in.)
Output(s)
Disp: Drill Pipe/drill Collar Displacement (bbl/ft)
W: Drill Pipe/drill Collar Weight \((\mathrm{lb} / \mathrm{bbl})\)
Formula(s)
\[
\begin{gathered}
\text { Disp }=\frac{\mathrm{OD}^{2}-\mathrm{ID}^{2}}{1029.4} \\
\mathrm{~W}=\text { Disp } * 2747
\end{gathered}
\]
