Conrad Schlumberger Award

Award for Outstanding Contribution
The Conrad Schlumberger Award is presented to a member of EAGE who has made an outstanding contribution over a period of time to the scientific and technical advancement of the geosciences, particularly geophysics. In exceptional circumstances, a maximum of two (2) Schlumberger Awards may be granted annually.

The Conrad Schlumberger Award consists of a medal and a certificate.

The Schlumberger Award 2016 is presented to

Stewart Greenhalgh

Stewart Greenhalgh is Emeritus Professor of Physics at the University of Adelaide and Professor at the Institute of Geophysics at ETH. In a career that has spanned three continents and has achieved the unlikely combination of both a DSc for outstanding published research and an explosives certificate from the Railways Institute of New South Wales, Stewart’s research has been distinguished by its innovation, depth, and breadth. He has authored numerous influential papers on theoretical, computational, and applied aspects of environmental, engineering, exploration, and whole-earth geophysics. Recognised by the Mintrop award in 2012, Stewart’s focus is not only on pushing back the frontiers but also on helping young researchers at all levels and on collaborating with others. His collaborations have benefited both cross-disciplinary academic research and a large number of companies with whom he has served in various consulting capacities.

Stewart has made significant contributions in numerical modelling of wave propagation in anisotropic media, physical scale modelling, seismic data processing and filtering, multi-component polarisation, tomography, migration, waveform inversion, vertical seismic profiling, in-seam seismology, high-resolution seismic for coal exploration and mine optimisation, microseismic monitoring, crustal and upper mantle studies, earthquake seismology and seismic risk. He has also ventured into electrical resistivity instrumentation, modelling and imaging, ground-penetrating radar, electromagnetic induction, and magnetic resonance imaging. With such an enormous range of scientific contributions, it is difficult to select one topic area as being pre-eminent but it is a sign of his continuing contributions that his current work on poro-elasticity and anisotropy in both seismology and electrical resistivity is considered to be some of his best.

For his sustained contributions to geophysics in both academic and industrial communities over a lifetime of research and teaching, the 2016 Conrad Schlumberger Award is given to Professor Stewart Greenhalgh.

Previous Winners Of The Conrad Schlumberger Award

Alain Tabbagh

Alain Tabbagh is Emeritus Professor of Applied Geophysics at the Université Pierre et Marie Curie, where his distinguished scientific career encompasses both fundamental rigour and practical developments. His research has impacted environmental geophysics and hydrogeophysics, hydrogeology, soil science, archaeology and civil engineering, with significant breakthroughs in surficial geothermal analysis, electrical and electromagnetic (EM) methods. Alain has developed new sensors for in-situ measurement of soil thermal properties and new finite-element models of the thermal response of bodies. He established the heat-exchange conditions at the soil surface favourable for remote thermal surveying and demonstrated the interpretation of near-surface contrasts in thermal inertia. Alain identified the impact of vertical water fluxes on soil temperature profiles and used such observations to interpret meteoric infiltration and recharge. In electromagnetics, Alain noted that the simultaneous estimation of soil conductivity and magnetic susceptibility was enabled by the Slingram antennae configuration. Together with 3D modelling of both conductivity and magnetic susceptibility contrasts from DC to medium- and high-frequency EM, his novel mapping and modelling methods have become pervasive in both archaeology and agriculture.

In geoelectrics, Alain has inspired the development of multi-depth resistivity profiling systems and associated 3D interpretation. He proposed the use of non-galvanic, capacitively-coupled arrays and established their optimal parameters. A prototype capacitively-coupled system was field-tested in the streets of Montreal and several commercial systems are now available. Prof. Tabbagh has given selfless service to the near-surface community: he has supervised some 40 PhD students, published over 130 articles and book chapters, and chaired the 2012 Near Surface Geoscience conference in Paris. He has been a director of two laboratories and is an associate editor for several journals. For his sustained contributions to science and the community over a lifetime of active teaching and research, we confer the Conrad Schlumberger Award to Prof. Alain Tabbagh.

Valentina Socco

Dr Valentina Socco received her MSc and PhD in Civil and Environmental Geo-Engineering at the Politecnico di Torino, where she now conducts both her research and teaching. As a teacher in the Petroleum Engineering Department, she has supervised 40 masters' and 5 doctoral theses and is now vice-director of the Doctorate School. As a researcher, she is head of the Laboratory of Applied Geophysics, at the Department of Environment, Territory and Infrastructures, where she leads or coordinates national and international projects with world-class research partners. Valentina's research focus is the theory and application of integrated geophysical techniques to characterise the near-surface, addressing problems in resource exploration, geotechnical and environmental engineering, and the preservation of cultural heritage. She has made original contributions to spectral analysis of seismic surface waves, and inversion for near-surface properties by integrating data from surface waves, body waves, resistivity and electromagnetics with a priori information.

Valentina is widely recognized, not only from her 32 peer-reviewed papers and 66 other publications on applied geophysics, but also through her invited lectures at many universities, international schools, workshops and conferences. Her conviction that excellence in science is also about sharing is demonstrated by her outstanding commitment to the near-surface community: as a supporter of the EAGE Near Surface Division, as Associate Editor of Geophysics and Near Surface Geophysics, as reviewer for many international journals, as a member of the Research Committee, and as a convenor of EAGE conferences and workshops for more than a decade. This award recognises the outstanding contributions that Valentina has made over more than 20 years to near-surface geophysics, her commitment to serve and share with the near-surface community, and her contributions to the Association.


Kees Wapenaar

From 1986 to 1999, Professor Kees Wapenaar was a project leader of the highly renowned Delphi consortium in the Department of Applied Physics at Delft University. In 1999, he became Antoni van Leeuwenhoek Professor in the Department of Geotechnology and has headed the Applied Geophysics and Petrophysics Section from 2002. Since 1986, he has co-supervised 30 PhD and 75 MSc students. Prof. Wapenaar made an outstanding contribution to geophysics by giving seismic interferometry a strong theoretical foundation, enabling research for applications in exploration seismology.

This award recognises Prof. Wapenaar’s extensive theoretical work on interferometric methods in multi-dimensional acoustic and elastic imaging, and on the practical implementation of this theory, to retrieve subsurface reflection responses from ambient noise recordings. Successful field tests have been conducted together with Shell. Prof. Wapenaar has actively communicated his interferometry research to the widest possible audience, delivering an EAGE distinguished lecture on the topic. He has been a driving force behind several workshops, sharing ideas and connecting different disciplines.
