A geoscientist's guide to petrophysics / Справочник геолога по петрофизике

As its name implies, petrophysics is the study and measurement of the physical properties of rocks. As soon as you start to take an interest in this field, you are struck by the duality between the “Physics” aspects and the “Geology” aspects. In most publications, the “Physics” aspect prevails, in other words the quantitative description of the laws governing the phenomena affecting the rocks subject to various stresses: hydraulic, mechanical, electrical, etc. The rock itself is generally no more than a “black box” whose microscopic structure is never described, or at best very briefly, as a model sometimes far remote from reality. This is because the evident rich diversity of the natural porous media scares the physicist, as expressed so well by G. Matheron [in French, 1967] “…ces millions de grains et la variйtй inйpuisable de leurs formes et de leurs dimensions….” (“…these millions of grains and the inexhaustible variety in their shapes and dimensions…”. <...>
