Original Paper


The Bengal Fan has attracted extensive attention from the oil industry because of its hydrocarbon reservoir potential. This paper characterizes the architectural elements and stratigraphy of the Upper Miocene-Pliocene Bengal Fan by high-resolution 3D seismic data. Seismic facies and strata slice technologies are applied to identify architectural elements. Six seismic facies are classified and interpreted as mass-transport deposits, channel complex including incised channel, leveed channel and sinuous channel, lobe complex, and hemipelagic deposits. Two seismic sequences and five internal sequences are divided according to the vertical evolution of deepwater sedimentary elements. By understanding and identifying the architectural elements and stratigraphy of the deepwater fan, we can propose potential drilling sequences of oil and gas reservoirs.
