Velocity sedimentary rocks

With respect to the velocity and its behaviour, there are two types of sedimentary rocks ... [Pg.189]

For most sedimentary rocks with porosity the lithological or mineralogical influence upon velocity is mainly expressed by the ... [Pg.190]

The differences in the elastic behaviour of these two groups are based on different physical conditions at the contacts of the rock particles. For the first group, conditions are controlled by friction effects, whereas for the second group, physiochemical phenomena are dominant. Similar to consolidated sedimentary rocks, there exists a significant correlation between velocity and porosity for unconsolidated sediments. Velocity in unconsolidated sediments is distinctly lower than in consolidated sediments. The compressional wave velocity shows a clear difference for the dry sediment (about 200-500 m s ) and water-saturated sediment (about 1600-2000 m s ). [Pg.193]

Figures 6.17 and 6.18 show the velocity-pressure behaviour of a porous sedimentary rock. In general, there is a characteristic non-linear dependence of velocity on depth or pressure. In most cases, wave velocities increase strongly with increasing pressure at low levels, and less at high pressure. Figures 6.17 and 6.18 show the velocity-pressure behaviour of a porous sedimentary rock. In general, there is a characteristic non-linear dependence of velocity on depth or pressure. In most cases, wave velocities increase strongly with increasing pressure at low levels, and less at high pressure.
The increase of the velocity with increasing pressure in sedimentary rocks is caused by ... [Pg.201]

In elastically anisotropic rocks, the velocity of wave propagation depends on the direction of propagation. Obvious anisotropy exists in sedimentary rocks with layering (bedding) and schists. Crampin and Lovell (1991) list five possible sources of seismic anisotropy ... [Pg.206]

The effects of mineral composition, porosity, and saturation are also different for sedimentary rocks with respect to the petrophysical properties density, velocity of elastic waves, and thermal conductivity. For a discussion of expected correlations, it is important to note ... [Pg.409]
