Production seismic processing sequence for 2D land project usually consists of the following steps:

•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)
