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…
Stratigraphic Detail From Wavelet Based Spectral Imaging
Adam Gersztenkorn and John Smythe, Barbara Radovich
Seismic interpretation has been based traditionally on seismic reflectivity strengths measured by amplitude. Modern workstations and interpretation software calculate a wide variety of attributes based on seismic amplitudes. Historically, analyses based solely on amplitude have posed a number of significant problems for the interpreter. Reflection amplitudes in seismic data are…
Light Up The World Foundation
Light Up The World Foundation (LUTW) is an international humanitarian organization affiliated with the University of Calgary dedicated to illuminating the lives of the world’s poor. There are over two billion people in the world without access to electricity. When night falls, their only source of light is usually a…
Great Challenges and Opportunities in Geophysics: the state of our technology, our business and the SEG
Craig Beasley
The profession of Geophysics faces significant challenges today. No doubt, the ability of our technology to remotely image the subsurface has provided significant value to the oil and gas industry. The competitive business climate of the oil industry continues to pit geophysical technologies against other alternative means of increasing production…
The Challenges of Change in the Exploration Industry
David Bartesko and Laurice Block
If there’s one thing that’s been constant in the geophysical industry for the past 10 years, it is, ironically, change. Adjusting to change is an ongoing challenge to industry. Over the past decade, companies and individuals have critically assessed the way exploration has been planned and conducted, and this has…
“Change is good donkey!”
Rod Garland
For those who don’t have kids, the above is a line from the movie Shrek. It also epitomizes the reality of field seismic contracting services over the past few years. Sure, sometimes we have to be dragged into the future, kicking and screaming, as we are by nature, conservative or…
Seismic–Managing the Risk
Ken Lengyel
Seismic data is recognized throughout the Oil and Gas industry as one of the tools available to industry that can have a significant positive effect on the F&D (Finding & Development) costs associated with developing a company’s reserve base. Unfortunately, within the Oil and Gas industry the inherent risk of…
Attributes in color: the early years
Nigel Anstey
Every old-timer lives for the day when someone will ask about the good old days. I need to start back in the mists. Even the early pioneers in seismics saw that there must be more to the seismic waveform than travel time. After the important clarifications given by Norman Ricker,…
Seismic Attributes – some recollections
Roy Lindseth
Few geophysicists can recall the days when a seismic record meant an 8 inch wide, 4 foot long banner of paper carrying 24 seismic traces. Each trace of each seismic event was carefully picked and the time of the reflection inked by hand. Even at that early time seismic attributes…
Significant Discoveries Marked ‘04
It may not have been a year for elephant discoveries, but in 2004 a number of important wildcats added to the world’s reserve inventory potentials.
... Ensuring Effective Basic Safety Awareness Training for Field Personnel
Dave Berte
In this age of increasing liability and requirements to ensure employee competency and safety in the workplace, employers are faced with the ever-increasing responsibility of providing effective training to employees, especially new employees, and those who undertake new or different duties. Where can employees go to get direction and assistance…
