PESA QLD: Technical Evening, November 19: Henry W. Posamentier on ‘Recent applications of seismic geomorphology/stratigraphy’
Guest Speaker(s): Henry W. Posamentier
Henry W. Posamentier is a worldwide consultant in seismic and sequence stratigraphy with a focus on lithofacies prediction risk issues. He was a Senior Geological Advisor with Chevron Energy Technology Company serving as a consultant to exploration and development business units on a wide range of geological issues, prior to retiring in 2014. Before Chevron, Dr. Posamentier served as Chief Geologist with Anadarko Petroleum and was a senior exploration and research advisor with ARCO and earlier with Exxon Production Research Company. Dr. Posamentier has published widely with research interests in the fields of sequence stratigraphy, seismic stratigraphy, seismic geomorphology, and depositional systems analysis, having been an early pioneer in the disciplines of sequence stratigraphy and seismic geomorphology. Most recently, he has employed an interdisciplinary approach to the prediction of lithofacies distribution through time and space by integrating stratigraphy, geomorphology, depositional systems analysis, and sequence stratigraphy, using 3D seismic visualization integrated with borehole data.
In 1971-1972, Dr. Posamentier was a Fulbright Fellow to Austria. He has served as an AAPG Distinguished Lecturer to the United States (1991-1992), an AAPG Distinguished Lecturer to the former Soviet Union (1996-1997), an AAPG Distinguished Lecturer to the Middle East (1998-1999), and an AAPG Distinguished Lecturer to Europe (2005-2006). In 2008 he was awarded the Pettijohn Medal for excellence in sedimentology from the Society for Sedimentary Geology (SEPM), the William Smith Medal for contributions to applied and economic aspects of geology from the Geological Society of London in 2010, and the Robert Berg Award for Outstanding Petroleum Research from the AAPG in 2012.
PESA Queensland welcomes 2025 PESA Distinguished Lecturer, Henry W. Posamentier to present a technical evening presentation on Recent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea. The technical evening will be held at the Transcontinental Hotel.
Due to the significant crossover with our peer society ASEG (Australian Society of Exploration Geophysicists), ASEG members are welcomed to attend at PESA member pricing.

Recent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea
Henry W. Posamentier
This presentation will document the seismic stratigraphic and seismic geomorphologic expressions of deep-water deposits of the Bay of Bengal and the Norwegian Sea. They comprise both turbidites as well as mass transport deposits. The turbidite deposits from the Bay of Bengal include leveed channel complexes, terminal fans, and overbank sediment waves. With respect to terminal fans, there are those that terminate basinward of leveed channel systems and are relatively large, and those that are deposited late within a lowstand cycle of deposition and are confined between the levees of precursor larger channels, and are relatively small. Intra-basinal channels (i.e., channels that start and end on the basin floor) are observed within abandoned meander loops as well as interchannel overbank terrains. These intra-basinal channels are characterized by low sinuosity and likely are mud-filled with no exploration potential.
Mass transport deposits from the Norwegian Sea include flows, slumps, and slides, as well as isolated outrunner blocks. These deposits are associated with significant substate erosion up to 250m. The outrunner blocks are observed in clusters, generally in radiating patterns down-system. Some of the outrunner blocks at the termini of erosional furrows are associated with sediment tails orthogonal to the direction of transport, indicating bottom current direction from southwest to northeast. In addition, volcanic intrusive deposits will be documented. These intrusives comprise both dikes and sills. Some of the dikes are associated with laccoliths in the shallower section.
