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.

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