Course Description:

The Inversion Boot Camp course is a survey and description of modern inversion methods available to explorationists. While there will be just enough mathematics, the emphasis will be primarily on concepts and understanding. Topics will include, "Which Tool to Use", "Quality Control", "Interpretation of Inversions" and the "Differences between Modern Inversions".

Presenter / Instructor Biography:

John Pendrel's academic career included a B.Sc. at The University of Saskatchewan in Regina (1968), and an M.Sc. from The University of Saskatchewan, Saskatoon, (1972). While at Saskatoon, he was part of a team investigating auroral magnetic fields from rocket-borne magnetometers. John also holds a Saskatchewan Class "A" teacher's certificate and served a brief stint as a high school physics teacher in Saskatoon. Leaving teaching, he obtained a Ph.D. in Geophysics from York University, Toronto in 1977 where his interests were in two-dimensional time series and spectral analysis.

He began his career in the oil industry in 1977 with Gulf Science and Technology Company in Pittsburgh, PA, the research arm of the former Gulf Oil Corp. His first direct report was Ralph Shuey, whose classic paper led to the wider use of AVO. Another colleague was Gerry Gardner, most-famous for his relation between density and velocity. While at Pittsburgh, John was a member of Gulf's tomography team and conducted research in the areas of pattern recognition and principal components analysis. From 1981 to 1995, he was Sr. Geophysicist and then Manager, Geophysical Technology with Gulf Canada Resources in Calgary.

John joined Jason Geosystems as Chief Geophysicist in 1995. There, he did applied research and published papers in Seismic Inversion, Geostatistical Analysis and AVO. In 2002 he became Business Manager of the new Fugro-Jason Canada. His current position is Regional Technical Manager, North America.

Away from work, besides playing on a hockey team, John volunteers with the Calgary Exhibition and Stampede where he serves on the Executive Committee of the Calgary Stampede Showband. He is also their photographer and has traveled extensively with the Band on overseas trips.

 

David Timko has a B.Sc. in Pure Mathematics and and M.Sc. in Statistics and Applied Probability from the University of Alberta. He joined the oil industry with Amoco in Calgary in 1980. Most of his early career was spent at either Amoco or BP working on exploration and development projects in western Canada with a brief interlude in Houston. In 2003 he won Best Geophysical Paper at the combined CSEG/CSPG convention. In 2004 he became the Technical Services Manager for Fugro Geoscience GmbH based in Dubai, U.A.E. His most recent assignment is Product Champion for Analysis and Interpretation with Fugro Jason giving direction to future software development.
