Nodal analysis views the total producing system as a group of components potentially encompassing reservoir rock/irregularities, completions (gravel pack, open/closed perforations, open hole ...

Observations on nodal and loop analysis that can save a fair amount of scribbling of equations when using Kirchhoff's laws.

As shown with a nodal analysis, the use of wellhead chokes on electrical submersible-pumped wells causes high hydraulic losses across the chokes and wastes considerable energy.
