OpendTect v4.2

Description

OpendTect is the first seismic interpretation system to support Wacom digitizing tablets. Workflows for horizon tracking, fault interpretation, drawing of polygons & bodies etc. have been adapted to benefit from the superior hand-eye co-ordination offered by the pen device. Watch Improved seismic processing with Wacom interactive pen displays on YouTube. Crossplots, PDF and Bayesian inversion The cross-plot tool has been enhanced considerably. It now supports colour-coding of wells & attributes and generation of Probability Density Functions (PDFs) and Bayesian inversion work flows. fault-handling Other highlights * Low frequency model building using HorizonCube data * Improved Stratigraphic Model building * Multimachine batch processing on Windows * Gridding using GMT algorithms * Improved 2D Viewer (e.g. added tree, horizon/fault tracking) * Export of cultural data to GoogleEarth: wells, survey area, 2D lines, random lines, polygons * Directional lighting * Interactive fault construction from faultsticksets * Translation of gui text using Google-translate * New toolbar icons New in the Closed Source part horizoncube-icon2 HorizonCube Game-changing new plugin that auto-tracks a dense set of horizons (e.g. a horizon every 4ms). The HorizonCube impacts all aspects of seismic interpretation work and allows the interpreter to extract more geology from the data. The HorizonCube is used for: detailed geologic model building, improving seismic inversion, sequence stratigraphic interpretation (SSIS) and correlating wells (new Well Correlation Panel). wcp-icon Well Correlation Panel New plugin to pick well log markers and correlate wells along (random) seismic tracks. In combination with the HorizonCube the Well Correlation Panel supports a HorizonCube slider for detailed seismic-steered correlations. Common Contour Binning CCB stacks can now be displayed flattened and un-flattened. In the latter mode hydrocarbon contacts are flat and therefore easier to interpret. Furthermore a new mode called "local CCB" is introduced. Data in this mode is stacked along contour lines within a user-defined radius. The technique enhances hydrocarbon effects whilst preserving local differences and is used to enhance subtle 4D effects in time-lapse studies.
