Ray theory: Travel times
Seismic ray theory is analogous to optical ray theory and has been applied for
over 100 years to interpret seismic data. It continues to be used extensively today, owing to its simplicity and applicability to a wide range of pro

SEISMIC EXPLORATION
Introduction
Seismic exploration is the 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 scientif

Oil and Gas India Limited Strikes Oil Near Kutch, Gujarat
Oil and Gas India Limited (OGIL), a major oil conglomerate has been doing
surveys in the offshore block DC-1 located near Kutch, Gujarat. Recently, an
exploration well has struck oil in that area.

FAULTS
Rock blocks on either side of fracture move relative to one another. Folds are classified on the
basis of the relative directi

Stress and strain
Any quantitative description of seismic wave propagation or of earthquake physics
requires the ability to characterize the internal forces and deformations in solid
materials. We now begin a brief review of those parts of stress and st

The seismic wave equation
Using the stress and strain theory developed in the previous chapter, we now construct and solve the seismic wave equation for elastic wave propagation in a uniform
whole space. We will show that two types of solutions are poss

Introduction
Every day there are about fifty earthquakes worldwide that are strong enough to
be felt locally, and every few days an earthquake occurs that is capable of damaging structures. Each event radiates seismic waves that travel throughout Earth,
