CSEG Bylaw Amendments
The following CSEG Bylaw amendments will be presented at the CSEG 2006 AGM on Monday March 27, 2006. Please note the changes/additions are printed in red.
... Azimuth Moveout Transformation – some promising applications from western Canada
Satinder Chopra and Dan Negut
Azimuth moveout (AMO) is a partial migration operator that rotates the azimuth and modifies the offset of 3D prestack data. Being a wave-equation based re-gridding algorithm, AMO carries the correct kinematic, phase and amplitude transformation, and handles dipping geological strata and variable velocity relatively accurately. These characteristics set AMO apart…
Attacking localized high amplitude noise in seismic data – A method for AVO compliant noise attenuation
Xinxiang Li and Rodney Couzens
The method of time-frequency adaptive noise suppression, or T-FANS, is designed to isolate and attenuate localized high-amplitude noise in seismic data. By “localized” we mean not only that the noise has a limited range in the space and time domain but also in the frequency domain. Strong ground roll energy…
Single Arrival Kirchhoff Prestack Depth Migration of complex faulted folds from the Zagros Mountains, Iran
Behzad Alaei and Jan Pajchel
Migration is an important stage in seismic imaging that focuses the recorded seismic data and generates a true structural image of the subsurface. In complex fault and fold thrust belts with rough topography, migration is difficult owing to lateral velocity changes and also very steep dips. The geometry of acquisition…
CSEG Distinguished Lecturer’s Tour Diary
I will start this journal by thanking the DL committee chaired by Dr. Mauricio Sacchi of University of Alberta and the CSEG Executive for selecting me as the first-ever Canadian SEG Distinguished Lecturer. This is a real honour and I promise to do my best to represent the high level…

... The Developing World Can Afford to Light Itself Up (It Just Needs a Wee Bit of Help!) LUTW
Dave Irvine-Halliday
Light Up The World Foundation (LUTW) is an international humanitarian organization dedicated to illuminating the lives of the world’s poor. It is the first humanitarian organization to utilize White Light Emitting Diode (WLED) or Solid State Lighting (SSL) technologies to bring affordable, safe, healthy, efficient, and environmentally responsible lighting to…
FUTURE SHOCKS: Modern Science, Ancient Catastrophes and the Endless Quest to Predict Earthquakes
Kevin Krajick
Brian Atwater paddled a battered aluminum canoe up the Copalis River pushed along by a rising Pacific tide. At this point, a 130-mile drive from Seattle, the 100-foot-wide river wound through wide salt marshes fringed with conifers growing on high ground. The scene, softened by gray winter light and drizzle,…
Leakage of the Indian Ocean Tsunami Energy into the Atlantic and Pacific Ocean
T.S. Murty, N. Nirupama, I. Nistor, A.D. Rao
The tsunami of 26 December 2004 in the Indian Ocean propagated not only throughout the Indian Ocean but also propagated into the Pacific and Atlantic oceans. Some of the tsunami energy from the Indian Ocean leaked into the Pacific and Atlantic oceans through the opening in the south. This leakage…
Tsunami Thoughts
Steven N. Ward and Simon Day
Truth to say, for most of the three decades that we’ve been involved, tsunami research has been a fairly sleepy field. There happened the occasional tsunami in Japan or Central America and the odd Pacific warning issued for never-materialized waves [“tsu-NO-mi” broadcast the next day’s headlines], but not much grabbed…
The Tsunami in Southeast Asia, December 2004
Edo Nyland
Although most readers understand aspects of the behaviour of earthquakes, some context may be useful to those who do not specialize in apocalyptic disasters like the Boxing Day 2004 event in the Indian Ocean. Context is also useful in considering how technical information was brought to bear on public policy…
Geophysical Exploration: Past and Future
Enders A. Robinson
Text of the invited lecture delivered by Dr. Enders Robinson at the Doodletrain Luncheon held at the Metropolitan Centre, Calgary on Oct. 31, 2005
... WHAT’S NEXT? Where is our Industry Heading?
The 2006 convention will be a joint meeting of the Canadian Society of Petroleum Geologists (CSPG), the Canadian Society of Exploration Geophysicists (CSEG) and the Canadian Well Logging Society (CWLS). Our theme is WHAT’S NEXT? Where is the industry heading? The technical programme is soliciting scientific, technical and business presentations…
A stable, accurate, and efficient approach to explicit depth migration
Gary Margrave, Hugh Geiger, Saleh Al-Saleh, and Michael Lamoureux
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.
... Using Ground Penetrating Radar for In-Seam Crack Detection in Potash
Chris Kelly, Dean Gerhardt and John Unrau
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. Also,…
3D Seismic Exploration for Mineral Deposits in Hardrock Environments
E. L’Heureux, B. Milkereit and E. Adam
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 associated…
Memoirs of successful geophysicists: Norman Domenico
A common acknowledgment when reviewing professional experiences and achievements is “I stood on the shoulders of giants”. This applies in my case. Following two years in the Naval Air Force (long ago becoming part of the U.S. Air Force) I returned to the Colorado School of Mines in 1946 to…
2005 CSEG DISC – followed by APEGGA Geoscience Student-Industry Mixer
Penny Colton
CSEG hosted the 2005 SEG Distinguished Instructor Short Course (DISC) on Tuesday September 27 at the Metropolitan Centre in downtown Calgary. Rodney Calvert, based in Houston with Shell, presented his full day SEG course entitled “Insights and Methods for 4D Reservoir Monitoring and Characterization”.
