Processing software

• FOCUS• Rayfract: Refraction tomography for statics

• Visual SIGHT for seismic modelling

• GeoVecteur for final processing in office

Page 25: Geo2x Reflection Seismic

• 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)
