Seismic Attributes Use For Channel Detection

Seismic Attributes Part 1 Pdf This study presents a comprehensive approach for detecting channel features in 3d marine seismic data by integrating conventional seismic attributes with deep learning based semantic segmentation. To highlight the channel structures and reduce the difficulties in identification, we used the geodesic distance map calculated from the seed points and two seismic attributes commonly used for channel identification as the inputs to the cnn model.

Seismic Attributes Part 3 Pdf I will apply conventional seismic attributes such as average absolute amplitude and energy attribute, and try to detect geometry of the expected channel in the study. We propose to adopt an encoder decoder convolutional neural network to directly detect 3d channel geobodies without human interpretation on precomputed seismic attributes. The structure and geomorphology of channel systems play a critical role in interpreting sedimentary processes and characterizing subsurface reservoir capacity. this study presents an innovative 3d ds transunet model for seismic channel interpretation. The application of seismic attribute techniques helps to reveal characteristics that is masked by using amplitude data themselves, and allows better geological interpretation of formation, particularly in channels and thin bed reservoir environments.

The application of seismic attribute techniques helps to reveal characteristics that is masked by using amplitude data themselves, and allows better geological interpretation of formation, particularly in channels and thin bed reservoir environments. Some key seismic attributes that can be used in the identification of channels are textural attributes, based on the grey level co occurrence matrix (glcm), a 2d matrix representing the. The most commonly used seismic attributes for fluvial channel interpretation include: coherence, curvature, and spectral decomposition. In this study, glcm based seismic texture attributes were used to interpret seismic data in order to locate channel structures. seismic texture attributes are a new means for identifying and interpreting seismic data. Seismic attributes continue to matter because they are fit for purpose transformations that enhance specific aspects of the seismic response discontinuity, texture, frequency content, geometry, and elastic sensitivity—making interpretation easier for both humans and machines.
