# Inflow Performance & Nodal Analysis

## Purpose

Demonstrates IPR curves using Fetkovich and Vogel models, then overlays a single-phase
VFP (tubing performance) curve to find the well operating point. The intersection of IPR
and VFP is the most fundamental production engineering calculation.

## Plan

- [x] Inputs sheet with reservoir, well, and tubing parameters
- [x] IPR comparison: Fetkovich vs Vogel (16 Pwf points)
- [x] Nodal analysis: IPR vs VFP at 18 rate points
- [x] Operating point chart (IPR + VFP intersection)
- [ ] Add skin sensitivity (S=0, 5, 10)
- [ ] Add tubing size sensitivity (2.375", 2.992", 3.5")
