Delineation of shallow channel geometry and infill lithology using Spectral decomposition and seismic attributes: A case study from the North Sea Basin, Netherlands

Abstract

9In the Southern North Sea, 3D seismic data had been widely acquired to explore for hydrocarbons, but 10 interpretations of these datasets until now focus mainly on the deep exploration targets of the petroleum 11 companies. Less attention is given to shallow sediments. But these sediments often contain channels that can 12 serve as potential reservoir units. Thus the mapping and identification of these shallow channels and defining 13 their infill lithology is important. In this study, seismic spectral decomposition technique has been used to 14 delineate shallow thin channel geometry in a 3D seismic data acquired in the Dutch sector of the North Sea.

Application of Spectral Decomposition and RGB Blending for Delineation of “S” Channel At Asri Basin

“…The thin-bed tuning effects occur when reflections from the top and down layer have constructive interference and the seismic data only show ¼ wavelength and if the layer thickness less then this value will not be detected (Okiongbo & Ombu, 2017). The wavelength itself depend on a frequency where high-frequency seismic data will reflect thin layer.…”
