SKUA introduces ‘paleo-chronologic’ interpretation framework

New interpretation technology from Paradigm transforms seismics to depositional space.

At the SEG, Paradigm personnel were sporting very green shirts in a visual rebranding exercise, emphasizing its status as a third upstream software pole, alongside Halliburton’s red and Schlumberger’s blue. The positioning was backed up by the roll-out of a brand new seismic interpretation tool, ‘Skua,’ for ‘subsurface knowledge unified approach.’


Skua’s origins are work done by Jean-Laurent Mallet’s team at the École Nationale Supérieure de Géologie in Nancy, France, the team that created Paradigm’s GoCad flagship geomodeler. Skua takes seismic data in the conventional time or depth domain and transforms it into a ‘paleo-chronologic’ coordinate system. An unstructured tetrahedral mesh that can be deformed and un-deformed places each cell at its depositional location. The process, which was developed under the GeoChron* consortium as a GoCad plug-in, is now commercially available from Paradigm.

No limits

Working with a palaeo-geographically ‘correct’ mesh, geobodies, reservoir properties and other attributes can be studied in their depositional state. Skua is claimed to facilitate model building and to circumvent the limitations of pillar grids and 2 D ‘extrusion’ representations. The full-3D balanced ‘paleo-chronologic’ restoration has been successfully applied to fracture studies of a deforming sedimentary layer**. GeoChron has also been shown to help in geostatistical reservoir studies by providing more realistic in-situ realizations of syn-depositional effects. More from
