Increasing precision in the interpretation of faults from seismic sections by analyzing the principle components of the attributes for determination of fractures in Gorgan plain

Introduction:

 In this study, using principal component analysis on seismic attributes, the main component with a high percentage of variance are prepared and presented in the form of appropriate sections. These sections can demonstrate smaller fractures and faults with better resolution. Although these images and sections diagnose faults well, presentation of these images in RGB color enhances the resolution of fractures. 

Methodology and Approaches:

 To raise quality levels of seismic sections, the attributes that have the optimal band combination of using statistical indicators are selected and by applying principal components analysis on these attributes, we obtain images that contain more information. 

Results and Conclusions:

 The resulting images, using the methods proposed in this study, have more details, and are more accurate, than the images obtained from other methods in showing faults and fractures.
