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

 

•Create project

•Load input data Geometry assignment and quality control

•Receiver Motion Correction

•Tidal Static correction

•Low Frequency Filter

•Spherical divergence

•Direct Wave and Coherent Noise attenuation

•Swell noise attenuation

•Debubbling and Zero-phase correction

•Deghosting

•Multiple Attenuation (SRME)

•Amplitude correction

•Residual random and coherent noise attenuation

•Velocity Analysis

•Residual multiple attenuation (Radon)

•Linear noise attenuation

•Pre-Stack Time Migration (PSTM)

•Multiple Attenuation (iteration 2)

•Residual moveout correction (Higher order)

•Residual time phase corrections

•Stack

•Post stack processing (additional noise attenuation, spectrum balance)

•AVO attributes and angle stacks

•Depth Migration (PSDM)

 

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