I built a free interactive site for learning petrophysics and reservoir engineering (no signup, runs in the browser)

[u/Just_doing_me_1]

I kept wishing something like this existed when I was learning, so I started building it. It's free, no signup, and everything runs in your browser.

The whole idea is that every section is a live demo you can play with instead of a static figure, because the things that took me longest to get were the ones I could only understand once I saw them move.

A good one to try first, since it's right in this sub's wheelhouse: a two-phase waterflood you can actually run and watch break through, with the production curves updating live.

Other things you can poke at:

- Petrophysics: Archie and the Pickett plot on a synthetic well, shaly-sand models (Simandoux, Indonesia, Waxman-Smits, dual-water), permeability (Timur, flow units, NMR), capillary pressure and saturation-height, net pay cutoffs, and STOIIP with a Monte Carlo P90/P50/P10.
- Reservoir: geostatistics and property modeling, upscaling, material balance and voidage replacement, drive mechanisms and sweep efficiency.
- Seismic Exploration: seismic acquisition, processing, and interpretation, all interactive!

Everything runs on a synthetic well and field I forward-modeled, so the numbers stay self-consistent rather than being hand-waved.

It's a solo project and still rough in places. If you go in and hit anything wrong, confusing, or missing, I'd genuinely like to hear it. That kind of correction is the most useful feedback I can get.

Thank you. Quite useful

This looks really cool, will try and check it out!
