If the rock contains a part of non-connected or separated pores (vugs, mol-dic pores), then this part does not contribute to any fluid transport within the rock and is non-effective . Thus, effective or interconnected porosity is the ratio of the connected pore volume to the total rock volume. For reservoir description it is therefore important to distinguish between ... 

This simplified picture neglects, of course, detailed molecular properties, yet it contains two important elements that are crucial for resolving heat flow at the nanoscale (1) Nonlinear effects may be easily included by considering an anharmonic-truncated molecular mode. In standard descriptions, anharmonic interactions are cumbersome to treat [17]. (2) Molecule-solid interactions and bath memory effects can be analyzed without being masked by the complicated molecular spectrum [22]. This treatment thus allows us to gain a qualitative understanding of heat conductance in single-mode junctions its dependence on the internal interparticle potential, molecule-reservoirs contact interactions, and junctions spatial asymmetry. 

Sams and Andrea (2001) describe the effect of clay in sandstone on elastic properties and present various model calculations. They start with some statements The shape and location of clay within sandstones have a large impact on the P-wave and S-wave velocities of the rock. They also have large effect on reservoir properties and the interpretation of those properties from seismic data and well logs. Numerical models of different distributions of clay - structural, laminar, and dispersed clay - can lead to an understanding of these effects . The description of clay effects and the derivation of models are difficult as a result of the following features (Sams and Andrea, 2001) ...
