Henry Posamentier (William Smith Medal)
The William Smith Medal is awarded for excellence in applied geology. For developing rigorous understanding of sedimentary successions, with direct impact on the successful exploration and production of hydrocarbons, there can be few more worthy recipients than Henry Posamentier. For his research has driven two of the great advances in understanding the rock record: sequence stratigraphy and seismic geomorphology.
A product of the US northeast, Henry studied in the City College of New York, moving to Syracuse for his Master’s and doctorate. After flirting briefly with academia, Henry built a career in the oil industry, starting in the seismic stratigraphy group at Exxon. Henry landed at the right place at the right time. The growing volume and quality of seismic data primed new insights into the evolution of stratigraphy, and its division into genetically related intervals.
This was seen as an inherently dynamic process, driven by fluctuating sea level - emphatically not Lyellian uniformitarianism, but something new that changed our view of sedimentary rocks. Henry was the lead author on a series of fundamental papers that put sequence stratigraphy on the map. After the annus mirabilis of 1988 when they were published, further significant contributions cemented sequence stratigraphy’s role as a fundamental tool for the interpretation of the sedimentary record, leading to successful exploration in deepwater clastic successions – the “new frontier”.
The advent of better data - high-quality 3D seismic data - also underpinned Henry’s second significant contribution. Seismic geomorphology is still young, but Henry is a pioneer. Henry has developed and promoted the use of seismic attribute maps to image depositional architectures so that the methods are now in routine use to trace out such hydrocarbon reservoirs as sandy submarine channels. Here, perhaps, the present is the key to the past, in that traces of ancient landscapes can be extracted from 3D data and interpreted just as one might interpret the modern sea floor or landscape.
Henry Posamentier, the oil and gas industry uses the approaches that you pioneered daily, to establish correlation frameworks and to characterise the geometry of hydrocarbon reservoirs. You are indeed a worthy recipient of the Society’s William Smith Medal for 2010.
Henry Posamentier replied:
I am highly honored, flattered, and humbled to receive the 2010 William Smith Medal. It is quite a thrill to be here in this hall in the shadow of giants and to be honored with a medal that bears the name of one of my heroes of geology making this very special, indeed.
This has been an amazing journey for me, starting from my early days growing up in New York City, my parents being new immigrants to the United States from Austria. To this day, people ask me how and why a chose a path of geology, given my upbringing in that urban jungle. It began for me much as it began for many a geologist – with a love of nature and love of the outdoors. It began simply, with geological field trips in the heart of New York City, and continued on to Alaska and many other parts of the globe. Along the way I have had many mentors, friends, and family to thank and acknowledge for all that they have taught me through the years. It all began with my first geology teacher, Simon Schaffel, to whom I will be eternally grateful for inspiring me with the thrill of geology. His unabashed love of geology was contagious and has never left me.
Many years later I had the good fortune of working with and being mentored by one of the giants in stratigraphy, Peter Vail. He was a role model for me in many ways, not the least of which was the way he encouraged and supported those he worked with, how he brought the best out of us all, and the way in which he created a climate of applied imagination and creativity. There were many others along the way in virtually every country I’ve lived and worked, who freely shared their insights and enthusiasm with me, but there is one other person to whom I owe an extra debt of gratitude. I could not have travelled the road I chose nearly as effectively had I not had the good fortune of having worked with David James, both a mentor and a lifelong friend, who with his patience and willingness to share his expertise in clastic facies depositional systems and stratigraphy, opened new worlds for me.
Lastly and most importantly, I thank my family for sharing this journey with me; it hasn’t always been easy for them. My wife, Ceri, has provided a strong family foundation despite our many moves and has always had a very unique way of keeping me grounded while providing unconditional love and support. My children, Joshua, Jordan, Michelle, Emma, and Rebecca, my true pillars of reality, I thank each of them for their unique brand of love and support.
