ABSTRACT: Integrated Previous HitSeismicNext Hit Texture Segmentation and SOM Cluster Analysis for Channel Delineation

Malleswar Yenugu

In recent years, 3D volumetric attributes have gained wide acceptance by Previous HitseismicNext Hit interpreters. The early introduction of the single-trace complex trace Previous HitattributeNext Hit was quickly followed by Previous HitseismicNext Hit sequence Previous HitattributeNext Hit mapping workflows. Three-dimensional geometric attributes such as coherence and curvature are also widely used. Most of these attributes correspond to very simple, easy-to-understand measures of a waveform or surface morphology. However, not all geologic features can be so easily quantified. For this reason, simple statistical measures of the Previous HitseismicNext Hit waveform such as rms amplitude and texture analysis techniques prove to be quite valuable in delineating more chaotic stratigraphy.

I coupled structure-oriented texture analysis based on the gray-level co-occurrence matrix with self-organizing maps (SOM) clustering technology and applied it to classify Previous HitseismicNext Hit textures. By this way, I expect that this workflow should be more sensitive to lateral changes, rather than vertical changes, in reflectivity. I applied the methodology to a 3D Previous HitseismicTop survey acquired over Osage County, Oklahoma, USA. The results indicate that this method can be used to delineate meandering channels as well as to characterize chert reservoirs.
