Pore Space

Pore space in rock contains oil gas or water.
Pore space. Microbial biodegradation and bioremediation 2014. In tight gas sandstone reservoirs water saturation is often negatively correlated to porosity ma et al 2011. Evaluating fluid saturations is an integral part of analyzing reservoir quality. Although it can be defined in a number of different ways pore space by its simplest definition is the empty space between grains of rock fractures and voids.
The pore space in a soil represents that part of the soil volume which has been occupied by air or water. Pore space is defined by porosity of a material possessing free space between the mineral grains expressed as percentage rebollo et al 1996 and depends on size and sorting of the particles as a cubic or hexagonic package. Pore space is generally thought of as a subsurface property right. The pore space of soilcontains the liquidand gasphases of soil i e everything but the solid phasethat contains mainly minerals of varying sizes as well as organic compounds.
In shale gas reservoirs gas in place includes adsorbed and free gas.
