Application of texture attribute analysis to 3D seismic data
Satinder Chopra and Vladimir Alexeev
In this study, texture attribute analysis application to 3D surface seismic data is presented. This is done by choosing a cubic texel from the seismic data to generate a grey-level occurrence matrix, which in turn is used to compute second-order statistical measures of textural characteristics. The cubic texel is then…
Looking inside Turtle Mountain: Mapping fractures with GPR
Ulrich Theune, Douglas Schmitt and Mauricio Sacchi
The rock avalanche at Turtle Mountain, Canada, in 1903 destroyed the town of Frank causing the death of approximately 70 people. The geological unstable mountain still poses danger for the surrounding villages. In order to prevent future causalities, the Government of Alberta initiated a detailed geotechnical hazard assessment of Turtle…
Seismic and Resistivity Imaging for Quaternary Channels, Rainbow Lake Northwest Alberta, Canada
Jawwad Ahmad and Douglas R. Schmitt
Buried channels are former valleys that were filled in as a result of recent glaciation. Such features contain high porosity sands and gravels often saturated with water or even natural gas, both of which are important resources. With regards to gas production, although the reservoirs found to date are quite…
Young Geophysicist Forum
On Tuesday May 17, the second day of the CSEG convention, the first meeting of the Young Geophysicist Form (YGF) was held at Ceili’s in Penny Lane. The purpose of the YGF was to allow current students, recent graduates, and individuals with less then 5 years experience the opportunity to…
Geologically Reasonable Vεδθ Models for Depth Imaging
Rachel T. Newrick and Don C. Lawton
... New Geological Timescale
The geologic time scale is the framework for deciphering the history of the Earth. A new geologic time scale has been prepared by a large number of experts working with radiogenic and stable isotopes, stratigraphers using diverse tools from traditional fossils to astronomical cycles to database programming, and geomathematicians. Contributions…

... Archaeological Reconnaissance at Tel Yavne, Israel: 2-D Electrical Imaging and Low Altitude Aerial Photography
Paul Bauman, Avner Goren, Richard Freund and Phillip Reeder
Tel Yavne in Israel is the site of the ancient city of Yavne. Located about 20 kilometers south of Tel Aviv, and about 8 km inland from the ancient seaport of Yavne Yam (meaning Yavne by the Sea), it is believed that underneath the tel (an archaeological mound) are the…
Pitfalls in 3-D Interpretation
Alistair Brown
As a consultant I am often in a position to review seismic interpretations by others. It allows me time to reflect on how geoscientists can improve interpretations and avoid pitfalls.
... 2004/2005 CSEG Scholarships
Erin Lamb-Fauquier
The CSEG Scholarship Trust Fund was established July 1, 1975 and is run by a minimum of three volunteers in any given year. Currently, the Scholarship Trust Fund is the only charitable organization associated with the CSEG, but will soon form the basis for the new CSEG Foundation presently being…
The Canmore Museum and Geoscience Centre
Rick Green and Helen Isaac
The CSEG is pleased to be a financial supporter of the Canmore Museum and Geoscience Centre (Museum) as part of its outreach programme to promote geoscience to the public. The Museum is situated in the new Canmore Civic Centre (902 7th Avenue) and is operated by the Centennial Museum Society…
17th Annual CSPG-CSEG 10km Roadrace and FUN RUN
With summer well on its way, it’s time to dig out those dusty (and possibly neglected) running shoes and get ready to join us for the 17th annual CSPG-CSEG 10km Roadrace and FUN RUN!

... Exploring for Atlantic Canada’s next giant petroleum discovery
Michael E. Enachescu and John R. Hogg
During the past five years, the Canadian Atlantic Coast has become an important world petroleum province with: 1) production from world-class oil and gas fields: Hibernia, Terra Nova (together 55,000 m3 or 350,000 bopd) and Sable gas project (12.5 million m3 or 450 million cubic feet per day); 2) future…
Earthquakes and Seismic Hazard in the Yukon-Beaufort-Mackenzie
R.D. Hyndman, J.F. Cassidy, J. Adams, G.C. Rogers, and S. Mazzotti
The prospect of new hydrocarbon production as well as gas pipelines from the Beaufort-Mackenzie region, and from Alaska has resulted in increased attention to the substantial earthquake hazard in the Yukon and westernmost Northwest Territories. In this article we describe the distribution of past earthquakes and the hazard estimates based…
Elastic Nonlinearity of Reservoir Rocks – A Paradigm Shift
Tawassul Khan and Sofia Khan McGuire
The current world oil supply and demand models are indicating a trend towards future higher prices and long-term shortages. The world’s growing dependence on oil, which may face shortages in supply, is a serious long-term challenge. The economic security of the industrial nations is closely tied to global oil market…
The anatomy of anisotropic diffusion filters
Xinxiang Li
This paper provides a detailed analysis of how anisotropic diffusion filters work on seismic data. The conventional trace mixing filter is shown to be an implementation of a specific diffusion process. Diffusion filters have different forms, ranging from the simplest linear isotropic (L-I) diffusion to the most complex nonlinear anisotropic…
Spectral Decomposition
Greg Partyka
Limited signal bandwidth and abundant thin layering interact to produce tuned seismic reflections with peaks, troughs and zero-crossings that rarely follow true geologic boundaries. Such interference plagues traditional seismic methods and hinders the extraction and characterization of subsurface information.
... 2-D Resistivity Surveying for Hydrocarbons – A Primer
Paul Bauman
2-D resistivity surveying is a technique that has taken advantage of solid state relays and modern inversion techniques to make an evolutionary leap from 1-D resistivity soundings, a survey method that has changed little after almost 90 years of practice. 2-D resistivity exploration has been used extensively for exploration in…
New developments in conventional hydrocarbon exploration with electromagnetic methods
Martyn Unsworth
Over recent decades, electromagnetic methods have been viewed with considerable suspicion by many in the hydrocarbon exploration industry. While highly effective in mineral and environmental geophysics, electromagnetic methods have played a minor role in hydrocarbon exploration. Since electromagnetic (EM) methods use signals that diffuse in the Earth, they cannot provide…
