Nodal Analysis and Flow Rate Calculations
Nodal Analysis in PIPESIM is a method used to evaluate the performance of the entire production system — from the reservoir to the surface facilities. It identifies the optimal operating point by balancing pressures and flow rates across different nodes (reservoir, tubing, choke, etc.).
Flow Rate Calculations involve determining how much fluid (oil, gas, or water) can flow through the system based on reservoir properties, fluid characteristics, and pipeline design under specific pressure and temperature conditions.
