Gerhard Pratt joined the Faculty at Queen's University in January 1998. His research interests are in the fields of seismic modelling, imaging and inversion. From 1992-1997 he was the Elf Lecturer in Geophysics in the Department of Geology at Imperial College, London. He has worked as a Wireline Engineer in the Petroleum Industry, and has been active as a geophysical consultant in a number of different fields. From 1996 to 2000 Dr Pratt was an associate editor of Geophysics (published by the Society of Exploration Geophysicists SEG (USA)).

Research Interests

Dr Pratt has been actively researching new methods in seismic wave modelling and imaging. He and his students have developed a number of innovations in these areas that make possible large scale forward and inverse modelling of exploration seismic data through numerical simulation of the full wave equation. Together they have been able to use these methods in imaging structures in a wide range of applications, from small scale site investigations to wide angle crustal seismology.

What's New

The CSEG "Recorder" ran this interview with me in the June 2008 issue.

Five submissions on Waveform Tomography

Together with Drew Brenders, Rie Kamei, and Brendan Smithyman, we have submitted four extended abstracts for presentation at the Rome meeting of the European Association of Geoscientists and Engineers, in June 2008.

Waveform Tomography 2008: Beyond the first arrival

I am proposing a repeat of this short course for April 2008. Please get in touch with me if you are interested in attending. Currently the course is tentatively scheduled for the week of April 28th - May 2nd, 2008.

This course was given twice previously at Queen's University in Kingston in 2004 and 2005. Participants attended from across Canada, the USA and Europe


Why Waveform Tomography?

The short course was preceded by a one-day workshop in which participants illustrated a variety of datasets to be used in future waveform tomography studies. For the workshop program click here

Canadian Society of Exploration Geophysics Distinguished Lecture Tour

The tour kicked off with the first lecture at the University of Calgary on Tuesday, October 9th 2007. Here are some links for further information:

I attended the EAGE 66th Conference in Paris (June 7-10, 2004), and participated in the BP sponsored workshop on "Estimation of Accurate Velocity Macro-Models in Complex Structures". As at the CCSS workshop, part of the focus of this workshop was another "blind test"; Drew Brenders and I processed the workshop data using waveform tomography:


This our waveform tomography velocity image from a 67 km line of synthetic data provided by BP. The part of the image not sampled directly by refracted raypaths has been dimmed. For more information see the poster. The original model has not yet been released by BP.

Drew Brenders and I attended the 12th International CCSS Workshop at Mountain Lake Virginia, from Oct 8th-11th, 2003. Part of the focus of the workshop was a "blind test", in which participants were encouraged to download a 2-D full-wavefield elastic wide-angle dataset and analyse it. You can find Drew's final results, and a comparison with the original model (now revealed) here. The full extended abstract of our paper is here.
