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.
