- Understand and examine data acquisition and processing quality control displays.
- Ask appropriate questions during data processing steps.
- Review of basics of reflection seismology: wave propagation and seismic amplitudes
- Seismic imaging techniques and principles
- Overview of 3D seismic data acquisition and quality control
- Improving seismic resolution: deconvolution, inverse-Q filtering and spectral whitening
- Velocity estimation, velocity field building and velocity uncertainty implications
- Near-surface problems and solutions: seismic datums and statics corrections

- This training course was designed for Seismic interpreters, geophysicists, geologists and exploration team members who use seismic data and need to understand the purpose and implications of the data acquisition and processing steps that lead to the final seismic images and derivative attributes. Also, the course is appropriate to early -career processing geophysicists seeking a rigorous foundation of the principles of data processing and seismic imaging.
