If you want to determine volume between a wellbore and casing, This volume, called the annular capacity and it is essential in drilling orations. This Casing Capacity (Annular Volume) Calculator make it easy for you. To calculate simply enter your values as hole diameter (in), pipe diameter (in) and hole length (ft) into the input fields of the tool. By pressing calculate button, it will display casing capacity (bbls).

The calculator also offer you advance level calculation. For advance calculation simply turn advance mode on, enter your values as total hole volume (bbls)and pipe volume (bbls) and press calculate button, It will display net annular volume (bbls).
