(pɔˈrɒs ɪ ti, poʊ-, pə-)

n., pl. -ties.
1. the state or quality of being porous.
2. (in rock or other natural material) the ratio of aggregated pore space to the volume of the entire mass: used as a measure of the amount of fluid, as oil, that a geologic stratum might hold.

The porosities calculated through petrophysics and seismic inverted data have been correlated to a satisfactory level.
The range of pyrolysis that corresponds to oil shale samples of different porosities is quantitatively analyzed, as depicted in Figure 8.
(2015) performed a study on the control of flow around the perforated cylinders having the porosities in the range of 0.1[less than or equal to][beta][less than or equal to]0.8 with an increment of 0.1.
In general porosities tend to be lower in deeper and older rocks due to cementation and overburden pressure stress on the rock (Rider, 1996).
For higher porosities, a different equation is required.
In this research, two commercially available software packages were used to simulate the elastic behavior of cement paste, where the elastic modulus of cement paste with different porosities was back-calculated.
To do this, we designed a new testing system that can simulate the properties of particle transfer and stress conditions, investigated the seepage-erosion properties under different water pressures and initial porosities, and finally proposed the critical relative conditions for water inrush.
Separators of different thicknesses such as 40 [micro]m with 45% and 48% porosities and 50 [micro]m with 41% and 50% porosities were used.
Layers with different porosities were formed by applying current densities of 5-50 mA.cm-2 in a solution of aqueous 38%wt HF and ethanol (2:3) electrolyte.
But the process of attenuating the aforementioned mismatch in stiffness by way of increasing the percentage of porosity has revealed that for higher porosities, intense stress localization occurs in the implant around the pore periphery, which leads to the reduction of the mechanical durability of the material, despite its enhanced compatibility with the surrounding bone material [10].
