The module will introduce and develop the concepts required to understand how seismic data are processed prior to interpretation and enable the trainee to understand how the data output can be affected by the methods and techniques used.

1. Understand the type of data used in processing (seismic vs non seismic)

2. Understand ways of viewing / sorting / manipulating seismic data and domains i.e. shot, cmp and offset domains.

3. Understand the concepts of testing parameters

4. Describe a processing sequence and signal processing techniques applied.

1. Introduction – definition of main steps involved in seismic processing – review of basic mathematics tools applied to the data. Description of reformatting and preprocessing.

2. Geometry update - definition of processing domains. Mutes & amplitude corrections. Q compensation. Deconvolution. Designature. Zerophazing. Dual sensor summation.

3. Noise characterization and attenuation. Modeling of the weathering zone - primary and residual statics corrections.

4. Seismic velocities. Velocity analysis. NMO Corrections. Anisotropy. Multiples characterization and attenuation. Regularization principles.

5. Pre stack time migration. Residual move out. Post processing. Typical processing outputs. Impact of geometry on data quality. Wide azimuth datasets examples. Time versus depth imaging.

Geologists and geophysicists who wish to understand the concepts involved in seismic processing and the complexities and pitfalls relating to processing techniques.
