Exploration Seismology

Seismic exploration is use of seismic energy to probe beneath the surface of the earth, usually as an aid in searching for economic deposits of oil, gas or minerals, but also for engineering, archeological and scientific studies. In exploration seismology, the method of seismic is applied at or near the earth's surface to measure the elastic properties of subsurface and to detect variations in those properties. And Variations in subsurface elastic properties may be demonstrative of changes in pore fluids or lithology. Exploration seismology has been applied for subsurface exploration of depths as great as 150 km; it is particularly useful for depths up to 10 km. For these depths, the seismic method is capable of detecting and spatially resolving features at scales as small as less or tens of meters. This resolving power is significantly finer than resolving ability of other remote geophysical methods for this depth regime. Because this region of the earth's subsurface includes nearly all of its gas reserves and oil , exploration seismology plays a prominent role in the energy industry
