SEISMIC ENERGY

A detailed Summary of SEISMIC ENERGY


Seismic energy is reflected (echoed) from interfaces as well as transmitted.

Strength of reflection depends on

Seismic speed contrast across interface

Density contrast across interface

Transmitted energy can be partially reflected by still-deeper interfaces

Travel-time, strength of "echoes" from layers below source measured

Travel-times give relative depth

Strength gives property contrast

Repeated at close spacings along profile (compare echo-sounder)

Result is seismic section, which mimics layer distribution in subsurface

Major tool in oil,gas exploration

Hydrocarbons trapped in deformed beds (for example, folds, domes)

Relative travel-time of reflections shows relative depths

Structural interpretation possible up to several km below surface

Seismic signal processing techniques focus on improving signal-to-noise
