Recent research

 PSS-Geo has internal research teams which continuously developing new modules and approaches in different areas of geo exploration. We collaborate and sponsor research institutes and consortia. Our partners: Delphi (Holland), WIT (Germany), IPGG SB RAS (Russia), UiO (Norway) and others.

 

  • Artificial Intelligence - Rock properties prediction from seismic traces (Innovation Norway grant 2020) (completed)

  • Non-stretched Stacking (in progress)

 

Rune Inversion (April 2019) - Artificial Intelligence

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. 

High-speed HighRes velocity estimation from seismic data

 

PSS-Geo AS developed a processing flow for High-Resolution Velocity construction based on two methods: Amplitude Inversion combined with Dynamic Auto Correlation or combined with Dynamic Time Warping. By combinations these two methods, High-Resolution Velocity field can be generated quickly, without big machine computation power. Implementation of High-Resolution velocity field is a useful attribute for seismic interpretation: lithology, geohazard  and fluid prediction.

Phase Decomposition

Thin layers and HC effects are often accompanied by phase anomalies. It can be detected by decomposing the phase.

  PSS-Geo Seismic Data Attributes

 

 

 

 

Seismic attributes - are quantities extracted or derived from seismic data. These attributes can be analyzed in order to enhance information that might be more subtle in a traditional seismic image, leading to a better geological or geophysical interpretation of the data.

We suggest a package of attributes that include classic set and Q-factor, Phase decomposition and Lithology.
