EasyTrace

EasyTrace is a multi-disciplinary 1D data processing and editing tool, featuring advanced spreadsheets and a wide range of functionalities for geologists and geophysicists.

Well data are often acquired in different formats, with different sampling rates, requiring appropriate processing for modern geological modeling. Geophysical and geological reservoir characterization both require specific log processing and editing, for example rock-typing from logs and cores, seismic signature analysis, and AVO feasibility analysis.

EasyTrace takes advantage of a true spreadsheet environment that offers advanced 1D data editing, analysis and processing functionalities to help geoscientists in their daily work.Easytrace is now plugged on OpenFlow platform and shares all its powerful capabilities with all the OpenFlow Suite Applications, especially CobraFlow and FracaFlow.
