The following choices contain densities of various materials. Based on these data, which will yield the fastest seismic velocity? A. 3.3 g/cm3 B. 2.7 g/cm3 C. 3.0 g/cm3 D. 5.6 g/cm3

D. 5.6 g/cm^3

Explanation:

On the average seismic velocity increases with increase in depth due higher the pressure and more compaction

sand and shales in the Niger Delta Basin density-velocity relationship is

P = 0.31*V^0.25

A derivation of the original Gardner equation to calculate the average densities for sands and shales in wells.

ρ = α * V^β

where

ρ = bulk density in g/cm3,

V = P-wave velocity,

α = 0.31 for V (m/s) and 0.23 for V (ft/s) and

β = 0.25.

Such that

ρ = 0.31 * V^0.25

So the fastest seismic velocity will be in the densest material which is D. 5.6 g/cm3
