Production seismic processing sequence for 2D land project usually consists of the following steps: •Load input data Geometry assignment and quality control •Seismic data QC and trace editing •Surface consistent amplitude correction •Noise attenuation before deconvolution (spikes, linear, ground-roll) •Surface consistent deconvolution •Velocity analysis (iteration 1, manual picking) •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 •AVO atributes and angle stacks •Depth migration (PSDM)
