Why I Keep Writing About This

Over the years, I’ve seen the same pattern repeat itself.

Good people.
Reasonable data.
Technically correct workflows.

And yet the work would still fail — not in the subsurface, but in reviews, decisions, and downstream consequences.

The equations weren’t wrong.
But the assumptions behind them were rarely stated, tested, or discussed.

That’s why I keep writing about these issues — in internal notes, articles, and posts like these — trying to describe how petrophysical models actually behave in practice.

Most formal training focuses on tool physics and derivations.
Very little time is spent on messy data, fragile cutoffs, model sensitivity, or how to defend results honestly when certainty doesn’t exist.

Over time, those notes and essays accumulated and eventually became a book:
Applied Petrophysics for Geologists.

It’s not a textbook.
It doesn’t claim one right answer.

It’s an attempt to write down how this work behaves in the real world — where defensibility matters as much as technical correctness.

If it helps someone walk into a difficult review with their credibility intact, then it’s done what I hoped it would do.

Consistently wrong.
Reliably useful.
