In Seismic Processing 3D LAND tutorial, a typical (but not mandatory) step-by-step processing sequence for 3D land data in g-Platform™ is presented.

 

•Create project

•Load data and Geometry

•Seismic data QC and trace editing

•Spherical divergence

•Refraction static correction

•Surface consistent amplitude corrections (SCAC)

•Noise attenuation before deconvolution (spikes, linear, ground-roll)

•Surface consistent deconvolution

•Velocity analysis

•Residual static correction

•Noise attenuation after deconvolution (linear, random)

•Multiple attenuation (iteration 1)

•Regularization and 5D interpolation

•Pre-stack time migration (PSTM)

•Residual moveout corrections (RMO)

•Multiple attenuation (iteration 2)

•Stack

•Foot prints attenuation

•Post-stack processing (additional noise attenuation, spectrum balancing)

•AVO attributes and angle stacks

•Depth migration (PSDM)

 

For training purposes, we recommend to use free seismic datasets available from SEG Wiki:
