What's new in v4.2

Wacom digitizing tablets

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.

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.

Other highlights

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).

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.

Seismic coloured Inversion and Seismic Spectral Blueing

These plugins come with  a new seismic viewer that allows the user to interactively evaluate results during parameter testing.
