Seismic borehole data interpretation

Seismic and borehole data interpretation is carried out by means of applying Paradigm® software packages:

SeisEarth KV - seismic data interpretation
Geolog - petro-physical analysis and geological interpretation of well log data
Stratimagic - seismic stratigraphic interpretation and seismic facial analysis
