Chapter 1 - Nodal Analys definition and fundamentals
The Nodal Analysis is the fundamental method used by production engineers to study and evaluate wells. Nodal analysis is a technique to determine the flow condition of a well through two subsystems: “Inflow” and “outflow” defined by a “node” (point reference). Nodal analysis concepts apply to wells in natural flow, artificial lift wells to injection wells and for this reason it is important to understand the purpose, assumptions, phenomena involved and the limitations of the method.
