Sample text

There are many types of anisotropy. One type, called transverse isotropy, behaves as though it were composed of thin isotropic layers. As a result, there is a difference between horizontal and vertical propagation velocities. Another type of anisotropy is found in rocks that have cracks running through them. In such cases, the velocity parallel to the cracks differs from velocity orthogonal to the cracks. Wave propagation Solutions of the wave equation for perfectly elastic, homogenous and isotropic media describe four different types of waves.

They may be completely filled with petroleum. Lenticular sandstones may be formed by sites like beaches, islands, river channels, or point bars. The shape of the sand body, in profile, indicates its original nature. See Figure 2–60. ORGANIC REEF REEF DETRITUS LAGOONAL Up-dip pinch-outs of coastal plain sands frequently occur. The Texas coast is a good example. The traps formed by these pinchouts are usually small in size. See Figure 2–62.

3–14) As a result, a simplified expression for P-wave reflection and transmission coefficients at normal incidence can be developed. 14) and where Z1, Z2 = acoustic impedance of layers 1 and 2, respectively The seismic record The objective of seismic data acquisition is to obtain data that can be related to subsurface geology. At various points on or near the Earth’s surface, an energy source is used to generate seismic waves that travel downward and are reflected at interfaces between geologic strata that differ in acoustic impedance.
