Seismic Acquisition Forum, Before the First Shot
Perry Kotkas
So I'm supposed to write a report on the Forum...? Would anybody actually want to read such a thing? Well, Nancy Shaw, President of the CSEG, said to try to make it interesting, so here goes...
... Exploration Applications of the Multipole Acoustic Log: A Case Study
Lee Hunt and Glen Hard
This paper will illustrate the role of the full waveform acoustic log as a useful tool in the exploration cycle of the example well. This cycle, as illustrated in figure 1 below, includes the petrophysical evaluation of a newly drilled location, the seismic inversion work that was used to identify…
Superfund: Calgary Science Teachers Survive Hurricane Frances
Nattalia Lea
While many CSEG members were putting around in Banff at this past year's Doodlebug, Bill Batycky was getting some first hand experience on what life with hurricanes was all about.
... The structural style and seismic image of thrust related folding in the southern Canadian Cordillera
Paul A. MacKay
The structural style of the southern Canadian Cordillera is dominated by thrust faults. Associated with the thrust faults are folds, typically a hanging wall anticline and a footwall syncline. Examples of thrust-related folds are exposed in outcrop throughout the southern Canadian Rocky Mountains. In outcrop these folds are characterized as…
Destination Mars
Nattalia Lea
The planet Mars is a mere 100 million miles away from Earth. Yet for 1,676 persons on the evening of October 6, this distance seemed insignificant at the Destination Mars CSPG/CSEG joint presentation. Here, results from the Mars Pathfinder Mission of July 1997 were revealed. Everyone gawked at the extra-ordinary…
Anisotropic Pre-Stack Depth Migration
Jennifer M. Leslie and Don C. Lawton
... Slip Slidin’ Away – Some Practical Implications of Seismic Velocity Anisotropy on Depth Imaging
Don Lawton, Helen Isaac, Jennifer Leslie and Rob Vestrum
We can no longer ignore seismic velocity anisotropy in seismic data processing. Laboratory and field studies have provided compelling evidence that shales exhibit intrinsic transverse isotropy (TI), in which the seismic velocity parallel to the laminations is greater than that perpendicular to the layering, with the difference being as high…
Geo-Triad ‘98 – A More Relaxed and Pensive Perspective
Doug Uffen
It was one eventful day in May 1996, when Jim Reimer called me up. He told me of a project that the CSPG, CSEG and the CWLS wished to conduct. In 1998, the three societies were to hold a joint convention. I think I remember agreeing to help out. So…
SEG ‘98 – Geophysics in The Big Easy
Nancy Shaw
It's only September 20th, but the International Exposition and Sixty-eighth Annual Meeting of Society of Exploration Geophysicists is already in the can. For those people who didn't get a chance to visit New Orleans, the Indian summer weather in Calgary was more hospitable than the heat and humidity of New…
General Hospital Implosion
Nattalia Lea
To join in the thrill of history in the making, an urban seismic survey was conducted by the University of Calgary's Geology and Geophysics Department to record the effects of the Calgary General Hospital Implosion. Such an idea was conceived by Walter Andreeff, a first year science student.
... Rock Physics for the “Real World”
Rosemary Knight
Geophysical methods are widely used in the earth sciences to obtain information about regions of the subsurface that we cannot directly sample. Determining the way in which the measured geophysical parameters are related to the material properties of interest (e.g. lithology, porosity, fluid content) is the objective of rock physics…
Web News
Nattalia Lea
Little did Malcolm Bertram know five years ago, that his early efforts to establish the CSEG's web presence would come of age. Back then, the New Zealand-born U of C's geophysics technician and computer systems administrator recalls, "It took awhile to get things going because in the early days, people…
Early Devonian Oil Discoveries in Western Canada
When I wrote The Richness of Discovery a history of Amoco Canada – my research helped uncover two documents that I believe are of considerable historical significance. Both were type-written, both are rare. My presentation today will deal primarily with these two documents.
... The CSEG Superfund Setting Precedent for Better Things
Nattalia Lea
Three years ago, former CSEG treasurer, Susan Eaton, debated over the future of a wad of money deposited in the CSEG bank account. "The money was in guaranteed interest certificates, earning very little interest," recalls Eaton. "It seemed to me that the money wasn't doing anything to make the organization… Seismic Reservoir Characterization (Sable Basin)
Robert Whale
The Sable Offshore Energy Project is a multi-company endeavor that formed in order to develop approximately five TCF of gas, contained in six fields in the Sable Basin of offshore eastern Canada. The reservoir sandstones in the Sable fields are late Jurassic and early Cretaceous in age and are interpreted…
Geo-Triad ‘98 Rocks, Risk, Reward
Nattalia Lea
It poured the night before. Oil prices plunged to anorexic levels on the previous Friday. And conference organizers, were neophytes, when it came to masterminding and executing the largest convention of its kind in Calgary for the last century. Never before had a joint convention been held , culminating the…
Avoiding pitfalls in geostatistical reservoir characterization: A survival guide
K. Hirsche, S. Boerner and C. Kalkomey, C. Castaldi
Geostatistics provide a powerful framework for combining sparsely sampled but accurate well information with the densely sampled but less precise 3D seismic information. When used correctly it can provide accurate estimates of reservoir properties and an assessment of the uncertainty and risks associated with our reservoir models. However, geostatistical tools…
Simultaneous Estimation of Statics and Velocity
Timo Tjan and Ken Lamer
Where subsurface is complex, reflection data from land seismic surveys often suffer triply – from statics variations, the presence of various types of noise, and imperfect moveout correction due to crossing events and non-hyperbolic movement that varies rapidly with midpoint. For such data, velocity analysis, already difficult due to the…
Geophysical Consortia in Universities – A Vehicle for Research and Education
Larry Lines
As we approach the twenty-first century, the discovery of petroleum and minerals continue to have a major impact on the Canadian economy. Oil exploration and production efforts are active on the Atlantic Coast, the Rocky Mountain foothills, and the Western Canadian basin. With this activity comes an increased demand for…
CGG Newsnotes
Four special CGC Committees (PUBLIC AWARENESS; COOPERATION; ECONOMIC GROWTH; EARTH SYSTEM SCIENCE) have been set up to implement a series of specific projects to enhance the Geosciences in Canada over the next several years. Reviews of these plans were undertaken at the last two CGC meetings and initial committee activities…
