Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3424849
... A detailed seismic stratigraphy framework for the deep-water Cenozoic deposits in North Carnarvon Basin, is developed using high resolution seismic data along with machine learning techniques. The workflow allows to characterize architectural elements and relate them to a sequence stratigraphy...

... and the cyclicity embedded in the geological record. Conventional timedomain analysis is carried out to understand the general trends in the IMFs, which enables us to better identify longterms cycles associated with Transgressive-Regressive (TR) sequences. Then, by appropriately selecting a given IMF and extracting...

.... In this high-frequency sequence stratigraphic investigation of a Neogene Gulf of Thailand fluvial system, there are three distinct pattern-types recognized: meander cutoff, channel chute avulsion, and entire abandonment. The first two patterns are local abandonment of channel segments during fluvial lateral...
