Application of seismic attributes in enhancing thin beds : An Example from North Sea

Abstract

Many potential reservoirs are found to consist of thin stratigraphic intervals which prove to be a challenging task to be interpreted from a seismic section. These thin stratigraphic intervals are considered to be potential hydrocarbon bearing zones. The analysis of the 3D seismic data set of the F3 block located in the north-eastern part of the Dutch sector of the North Sea, shows the presence of such intervals. These thin beds are analysed using spectral decomposition technique and comparative results of different algorithms used in this technique have confirmed their presence. The blending of monochromatic colours brought out their presence in a much more enhanced way.
