# Field Production Profile — Buildup-Plateau-Decline

## Purpose

Three-phase field production profile with formula-derived phase transitions. Named input
cells for buildup time, plateau duration, plateau rate, and decline parameters. 25 time
steps out to 120 months.

## Plan

- [x] Inputs sheet with named cells and derived phase boundaries
- [x] 25-step production forecast with formula-derived Phase column
- [x] Rate and cumulative charts
- [ ] Add multi-well aggregation example
