Q- factor estimation

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

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.

Noise Reduction

Tenzor based regularization

-noise reduction

-faults preservation

Post stack  process with demigration and migration for easy structural interpretation.

Gravitymagnetic surveys on Drons

accompanied with shallow seismic or Radar scan for engineering and archeology needs.

PSS-Geo accomplished development of engineering solution of light weight Dron servery acquisition. Field' tests were carry out in several terrais. First archeological servery for research planned on summer 2018 in Romsdal Fjord, Norway, Viking's barrows.

PSS-Geo Seismic Data Attributes

 

 

 

 

Seismic attributes - is a quantity extracted or derived from seismic data that 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 the attributes that include classic set and Q-factor, Phase decomposition and Lithology.
