Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and
gas fields and geothermal systems, and the extent and connectivity of the pore structure …

In principle porosity is a very simple concept but because of the many different ways in
which it may be determined it can, in detail, mean many subtly different things. In the vast …

The term porosity is very widely used in geosciences and normally refers to the spaces
between the mineral grains or organic material in a rock, measured as a fraction of the total …

An investigation of equivalent pore entry radii in typical samples of petroleumreservoir rock
and the pore volume associated with each value of pore entryradius has been made …

With the increasing interest in unconventional resource plays, there have been important
changes in the way how reservoirs and their attributes are assessed and characterized. Of …

Several types of porosity (total or physical, advective flow, advective and diffusive transport,
and geochemical) can be distinguished in a mudrock. Each may have a different value …

Much secondary porosity has been created in sandstones after their burial by leaching of
carbonate and sulphate minerals. Secondary porosity constitutes the predominant or …

Permeability and formation factor are physical properties of porous rocks useful for
assessing reservoirs. Neither property varies consistently as porosity varies. The …

A simple network model of pore space in rocks has been developed with which permeability
and bulk modulus as a function of confining pressure can be calculated. Pores are modeled …

For this study, a unified network model was developed which represents the pore space of
sedimentary rocks as a 3-D interconnected network of pore throats and nodal pores. By …
