By determining the hydraulic flow units (HFUs) in the reservoir rock and examining the
distribution of porosity and permeability variables, it is possible to identify areas with suitable …

Seismic attributes are useful tools for identifying and characterizing geological properties.
Seismic interpretation can be supported by seismic attribute analysis. Common seismic …

Geological events such as thin beds and channels cannot be easily revealed on seismic
sections due to the interference of reflections from the top and bottom of the layer. Buried …

The signal quality of Magnetic Resonance Sounding (MRS) measurements is a crucial
criterion. The accuracy of the estimation of the signal parameters (ie E 0 and T 2⁎) strongly …

In processing of deep seismic reflection data, when the frequency band difference between
the weak useful signal and noise both from the deep subsurface is very small and hard to …

To locate the oil and gas reservoirs, seismic surveys need to be carried out and detailed
interpretation need to be done by geophysicists. In this chapter, basic knowledge of seismic …

The results of pre-stack depth migration reflect subsurface structures directly. However, it is
an urgent geophysical problem that how to deal with this non-stationarity exhibited by depth …

Structural features, such as faults, acts as traps and a conduit for the migration of
hydrocarbon, while stratigraphic features, such as channels and point bars act as reservoirs …
