AI solutions as a base for Geohazards, Lithology  and pore pressure prediction

We suggest DTW and *Rune Inversion techniques as a base for Geohazard, lithology and porosity prediction when seismic gathers or only stacked data are available.

High-resolution geohazard, pore pressure, lithology and porosity studies are provided in cooperation with ModelGeo.

Seismic velocity is an attractive parameter for geohazard interpretation, pore pressure analysis, play and prospect evaluations, and other geological studies, but ordinary seismic processing velocities often do not have a good enough resolution. We adapt a dynamic time warping algorithm to estimate geologically reasonable high-resolution velocities from average-quality seismic data that can be used for geohazard analysis based on 3D seismic data. To predict free gas and/or excess pore water pressure in thin shallow layers, we use velocity inversion. It is a method for simultaneous inversion of velocity data to geological attributes.
