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)).
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.

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:
To request that the tour visit your institution, please contact me.
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.
