Since, the early oil and gas exploration in Malay basin, structural traps such as anticlines have emerged as the primary prospect in almost all fields in Malay basin. The previous exploration in B field focused on the prospect of low-relief anticlines. This research is done to provide a new insight on oil and gas exploration in Malay basin through stratigraphy exploration by using the method of spectral decomposition. Spectral decomposition is applied to the three-Dimensional (3D) seismic data of B field located in Malay basin for stratigraphy exploration and evaluation. Spectral decomposition is used to image the lateral and vertical distribution of channels as well as for hydrocarbon detection in the reservoir. The results of spectral decomposition can be viewed in single component (frequency) or in multi-components display through Red, Green and Blue (RGB) displays. The results are compared with other volume attributes such as variance and sweetness attributes. © Medwell Journals, 2018.
