Seismic Signal Processing Results


Seismic signal processing techniques focus on improving signal-to-noise ratio(SNR) and   resolution of seismic data from pre-stack throught to post-stack. We have built these techniques as stand-alone software products, and software modules for other commercial products, such as DISCO/Focus by Paradigm Geophysical Ltd and GRISYS by CNPC, according to custumers' requirements.

The following pictures show field data examples by applying our latest techniques.
