Applied Petrophysics for Geologists
A Practical Philosophy for Working with Real Data
Applied Petrophysics for Geologists is written for professionals who must make subsurface decisions with imperfect data.
Rather than beginning with idealized physics, this book starts where real problems appear — messy logs, uncertain depth control, fragile cutoffs, and interpretations that must withstand technical scrutiny. It focuses on practical workflow, disciplined assumptions, and defensible decision-making.
This is not a textbook.
It is not a reference manual.
It is a working guide for applying basic petrophysics responsibly in operational and consulting environments.
The central premise is simple:
Petrophysics is interpretive, empirical, and approximate — and still incredibly useful when uncertainty is understood and managed.
What This Book Covers
What logs actually measure — and what they don’t
Building a “good-enough” petrophysical workflow
Porosity and water saturation without false precision
Clay volume vs. shale volume and why it matters
Cutoffs, net pay, and the art of drawing defensible lines
Core–log mismatch and how to use it productively
Sensitivity analysis for real-world decision support
Communicating uncertainty to reservoir engineers and management
The emphasis throughout is transparency over complexity and stability over elegance.
In subsurface work, being consistently wrong in useful ways matters more than being precisely wrong with confidence.
