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.
