Field processing software:Visual SUNT of W_GeoSoft/
GEO2X for Windows Xp
•Developed, maintained & upgraded by GEO2X•Powerful, versatile, fast, simple.•Very popular, used by more than 160 companies and institutions, including the majors: CGG, Schlumberger, Fugro, King Fadh University of Petroleum and Minerals , Petrobras, Repsol, GGD Geophysik, Japan Energy Development…
Processing software
• FOCUS• Rayfract: Refraction tomography for statics
• Visual SIGHT for seismic modelling
• GeoVecteur for final processing in office
• ECHOS / FOCUS 2D Processing System (Paradigm Geophysical)
• FOCUS (2D and 3D seismic data processing) is the complex system for 2D and 3D seismic data processing providing the up-to-date data processing technology based on the projected graphic interface.
• The System’s capabilities to perform data analysis and quality control by interactive visualization devices enable quick decision making and technological solution.
• FOCUS specifications provide efficient processing of large-scale data volume.
Geo2X geophysicist processes the data on the field: we shoot in the morning,
you interpret in the afternoon
ADVANTAGES
• Quality control
• Very adaptative
• Infill seismic acquisition if necessary
• Daily output of stacked section
(60 – 80 % quality of final section)
Data processing:Field quality controland pre-processing
