A new subject entitled “Attributes” has been added.
In the “ Near surface geophysics” subject, the lesson “ Flow” has been added.
In the “Stochastic Signal Processing” subject, the lesson “Depth conversion” has been added.
The subjects “Seismic applications” and “ Dispersive waves” have been merged in a single subject” Seismic applications”
The “ Attribute” subject is composed of 6 lessons. In the session, we give the fundamentals on the main seismic attributes. We show how signal processing tools are used to create the attributes. Through examples, we illustrate the applications of seismic attributes to seismic processing and interpretation:
• Envelope
• RMS-Amplitude
• Instantaneous Phase
• Instantaneous Frequency
• Dip & Azimuth
• Coherency
Now, the different subjects that are tackled are:
• The Fourier Transformation
• Common functions in spectral analysis
• Sampling
• Correlation
• Wave separation
• Seismic applications
• The Hilbert transformation
• Filtering
• Near Surface Geophysics
• Stochastic Signal Processing
• Attributes

A new theme entitled “The Hilbert transformation” has been added. Some additional lessons have been introduced in the topics “wave separation” and “seismic applications”.
In the “Wave separation” subject, the following lessons have been added:
• Vertical Seismic Profile
• Selection of a Rayleigh wave by a polarization filter
In the “Seismic applications” subject, the following lessons have been added:
• Dispersion analysis of Rayleigh waves
• Love Waves
• Refaction-Reflection seismic survey
• Seismic processing with an industrial software
• 3D seismic example
The Hilbert transformation subject is composed of 8 lessons which illustrate the main applications of the Hilbert transform in seismics:
• computing an envelope
• introducing a phase change
• measuring the instantaneous frequency of a sweep
• computing an analytic signal
• studying the polarization of a wave
• separating wave by polarization filters
• studying group and phase velocities
• transforming a signal into a zero phase signal
Now, the different themes that are tackled are:
• The Fourier Transformation
• Common functions in spectral analysis
• Sampling
• Correlation
• Wave separation
• Seismic applications
• The Hilbert transformation
