PetroTools — the engineering toolkit for petroleum students

PetroTools brings essential petroleum engineering calculations to your phone — fast, offline, and explained step by step. It's built for students who want to check their work, study smarter, and stop rebuilding the same curves by hand before every exam.

No login. No internet required. Every calculation runs right on your device.

AVAILABLE NOW: IPR CALCULATOR

Build the complete Inflow Performance Relationship (IPR) curve for a well — even when you don't have the productivity index.

Don't know the PI? Just enter a well test point (flow rate and bottomhole pressure) and the bubble point pressure, and PetroTools derives everything for you. Handles all three cases correctly: saturated reservoirs, tests above the bubble point, and tests below it. Uses Vogel's equation and the composite (linear + Vogel) model — the same methods from your reservoir engineering course. Calculates the AOF (Absolute Open Flow) and marks the bubble point on the curve. Plots an interactive IPR chart you can explore by touch. WHY STUDENTS LIKE IT

Every step explained. Each result comes with a full worked solution: the formula, the substitution with your actual numbers, and the answer. It reads like a solved example from your textbook, so you learn the method, not just the answer. Works offline. Everything is calculated locally. No account, no sign-up, no data collection. Made for learning. Clear inputs, the formula shown alongside every result, and a clean dark interface that's easy on the eyes during long study sessions. MORE TOOLS ON THE WAY

PetroTools is a growing toolkit. Planned additions include:

Nodal analysis: operating point from tubing performance (TPC) PVT correlations Decline curve analysis Have a tool you'd love to see? Your feedback shapes what gets built next.

Whether you're preparing for an exam, checking a homework problem, or just want reliable engineering calculations in your pocket, PetroTools is built to help you understand the how, not just the what.
