Summary:

The pioneering work of Gus Archie moved log interpretation into log analysis with the introduction of the equation that bears his name. Subsequent developments have mixed empiricism, physics, mathematical algorithms, and geological or engineering models as methods applied to petrophysical measurements in boreholes all over the world. This book reviews the application of mathematics to petrophysics in a format that crystallizes the subject as asubdiscipline appropriate for the workstations of today.
