Effects of pore and differential pressure on compressional ...

vestigation of the effect of pore fluid pressure on attenuation properties of candidate reservoir rocks is particularly impor-tant for evaluating the reservoir properties. For example, the seismic inference of pore pressure buildups could provide use-ful information about the fluid content and pore geometry of a reservoir (Green and Wang, 1986).

Gravel - Wikipedia

Gravel / ˈ ɡ r æ v əl / is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments.In the Udden-Wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with ...

Effective pressure or what is the effect of pressure?

pore pressure. Therefore the effective-pressure coefficient is smaller than one. When the effective-pressure coefficient approaches zero, the pore pressure has no influence on deformation, velocity, or permeability. When a rock is subjected to constant differential pres-sure, pore pressure has to be changed accordingly; there-
