A stable, accurate, and efficient approach to explicit depth migration

Gary Margrave, Hugh Geiger, Saleh Al-Saleh, and Michael Lamoureux

…Abstract This presentation will encompass the material of our 2005 convention paper of the same name but with more background. I will discuss the general concept of seismic depth migration by downward continuation using wavefield extrapolation. Wavefield extrapolation imaging (also known as wave-equation migration) has theoretical advantages over the more…

Using Ground Penetrating Radar for In-Seam Crack Detection in Potash

Chris Kelly, Dean Gerhardt and John Unrau

…Abstract Increases in ground falls over the last few years have prompted the Saskatchewan potash industry into researching new ways to increase mine safety and awareness. Ground conditions in a potash mine are very dynamic and the back stability changes continually due to the pseudo elastic nature of the ore.…

3D Seismic Exploration for Mineral Deposits in Hardrock Environments

E. L’Heureux, B. Milkereit and E. Adam

…Summary Conventional seismic reflection methods have been used with great success over the past decades to explore sedimentary environments for petroleum resources. To apply these same methods to mineral exploration in hardrock environments we need to adapt the time-tested seismic techniques developed for oil and gas exploration to the problems…

Memoirs of successful geophysicists: Norman Domenico

Expert Answers

…Question Since the early 1990s 3D seismic has become the norm for oil companies and it has helped get clearer pictures and more detail of the reservoirs. Conventional seismic interpretation methods as applicable to 3D seismic volumes make use of 2-D inlines, crosslines and time slices. Visualization and volume interpretation…

The MEGATEM fixed-wing transient EM system applied to mineral exploration: a discovery case history

Richard Smith, David Fountain

…Introduction In the mid-1980s, Geoterrex (later Fugro Airborne Surveys) introduced the GEOTEM system, a fully digital airborne electromagnetic (AEM) receiver, using the same transmitter that had previously been used, very successfully, on the INPUT system (Annan, 1990). The GEOTEM system is mounted on a twin engine CASA 212 aircraft, and…
