In Seismic Processing 2D LAND tutorial, a typical (but not mandatory) step-by-step processing sequence for 2D land data in g-Platform™ is presented.

 

•Create project

•Load input data Geometry assignment and quality control

•Seismic data QC and trace editing

•Spherical divergence

•Surface consistent amplitude correction

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

•Surface consistent deconvolution

•Refraction static correction

•Velocity analysis (iteration 1, manual picking)

•Residual static correction

•Velocity analysis (iteration 2, auto picking)

•Noise attenuation after deconvolution (linear, random)

•Datum planes

•Multiple attenuation (iteration 1)

•Anisotropy pre-stack time migration (APSTM)

•Residual moveout correction

•Trim statics

•Multiple attenuation (iteration 2)

•Additional denoise

•Stack

•Post-stack processing

•AVO atributes and angle stacks

•Depth migration (PSDM)

 

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

 

•2D Land - 2D Vibroseis Line 001 (this dataset also available with g-Platform™ installation package and default path is C:\Program Files (x86)\Geomage\gPlatform\demodata\Poland_2D_Vibroseis_LINE_01).
