Abstract

The addition of new reserves from mature basins such as Malay basin requires a stratigraphic approach that encompasses locating subtle stratigraphic traps and improving the reservoir characterization of the producing fields to deliver more production. Seismic attributes controlled by well information and aided by many interpretation and visualization tools can provide a lot of geological and stratigraphic information from a 3D seismic volume. In this study, a number of seismic attributes that has a demonstrated ability to delineate stratigraphic elements and lithological variations have been applied to investigate the stratigraphic architecture and sand distribution of an Upper Miocene reservoir in an undeveloped field, Northern Malay Basin. The interpretation of the attributes (i.e. spectral decomposition, coherence, RMS amplitude, and sweetness) along with the fluvial geomorphology analysis indicated that the reservoir interval is a meandering fluvial system. Fluvial depositional elements that include channels, point bar, scroll bar, and crevasse play have been interpreted. The Sweetness attribute highlighted high amplitude anomalies related to the sand-prone depositional features. These anomalies interpreted as hydrocarbon sweet spots. © 2018. All Rights Reserved.
