Rune Inversion (April 2019) - Artificial Intelligence (Patented, NIPO 20210133)

The very first Seismic Post-Stack Inversion algorithm that allows to estimate Velocity and Density separately; with no well logs data required! Inverted Density and Velocity used as a base for Vclay, Porosity and Reservoir quality attribute - (1-Vclay)*Phi computations. Read theory here.

Contact person: Vita Kalashnikova


Rune Inversion algorithm was used to invert the mega grid (post-stack data) of the Norwegian Sea


The map with reservoir quality attribute (1-Vclay)*Porosity is shown on the picture below (Gromer Knoll Gr). The arbitrary lines show predicted volume of sand-clay that are calibrated to 142 wells

The Norwegian Sea Sands


Public vintage data. 


Example 1

Cross-seismic time section going through the oil&gas well 35/11-23 NPD fact page. Data was deghosted prior to inversion.   

Jurassic sands are standing out on reservoir quality attribute - yellow color, about 2.1s.


Example 2

Cross-seismic time section going through the AErfugl and Skarv oil&gas fields. NPD fact page.

Sands are standing out on reservoir quality attribute.



Example 3

Volume of Clay-Sand predicted from the merged post-stack seismic data as part of the LL-Link project.

The volume is available for the entire Norwegian Sea.
