CSEG/CSPG/APEGGA Liaison Committee
John W. Peirce
The CSEG/CSPG/APEGGA Liaison Committee has been focussing on issues of concern which have been raised by geologists and geophysicists who have complained about certain APEGGA policies. Our goal is to try to facilitate change from within the system in order to demonstrate that APEGGA can be sensitive to members' needs…
Trends in Seismic Data Acquisition – A Perspective
Kevin Williams
Many of the technical changes taking place in the oil industry are evident in the office of the explorationist. Desk top processing, workstation based 3D interpretation and visualization packages are familiar tools to the "state of the art" geophysicist.
... Limitations on the performance of field arrays and FK filters: models, case histories and remedies
John L. Varsek and Rod Morris
Not generally appreciated at first glance, but nonetheless crucial to understanding the recording and imaging of reflections, is the linkage between acquisition arrays and fk filters.
... Magnetic Tape “Stiction” Problem
Norman R. Pascal
At the November 1991 SEG Convention, Memorex Computer Supplies, a major manufacturer of magnetic tape; presented a white paper titled "Understanding Magnetic Tape Stiction and its Solutions" and reiterated this theme at a seminar held in Calgary on November 4, 1992. Other tape manufacturers currently distribute literature on the same…
S.E.G. Gold and Silver Certificate Recipients

Silver Certificates - Roy F. Bjornson, David C. Caldwell, D.K. Bruce Fenwick, William E. Glenn, Charles R. Grigg, Emmanual Malterre,…
Synthetic Study to Estimate Errors in Wavelet Estimates and Distortions Introduced by Them in Velocity Inversion
Sudhir Jain
It is highly unlikely that the actual propagating wavelet for a seismic trace can be estimated precisely since the seismic data as well as the sonic and density logs are plagued with numerous imperfections, and the source-wavelet is altered in an undefined way by imperfect elasticity of the transmitting medium,…

... Environmental Geophysics - Fad or Future?
Dr. Phillip Romig
This lecture is one of 14 to be presented between September and January by Dr. Phillip Romig) head of the Department of Geophysics at the Colorado School of Mines since 1983.
... 1993 CSEG Convention
Dan Hampson
The 1993 CSEG Convention was clearly a success. Many factors contributed to that success. The Convention Committee would like to take credit for them all, but modesty forces us to admit that we had nothing much to do with the tremendous upsurge in optimism and enthusiasm that just happens to…
Canadian Geophysical Union Scientific Meeting
J. B. Merriam
Following a very successful joint meeting with the AGU In Montreal in 1993, the Canadian Geophysical Union returned to its regular venue at Banff, Alberta, in 1993. One hundred and forty-two papers were presented in 16 sessions.
... Geophysics at the U of S
Don Gendzwill
We have a new building which the department has occupied since 1986. The old geophysics “shack” is only a memory. For recent graduates, this is old news, but some of the older alumni may not have seen the new building. It is very nice, occupying a space on the edge…
Multidisciplinary Research at the Pacific Geoscience Centre
Melvyn E. Best

The CSEG Ladies Auxiliary held their 1993 Annual Ski Spree at Fairmont Hotsprings Resort on February 5th, 6th and 7th. There were over 230 people in attendance.
... Summary of the Workshop on Imaging Complex Land Data (CSEG Convention, May 7, 1992)
Peter Cary
Peter Cary organized this workshop with the help of other members of the technical committee of the 1992 CSEG National Convention. He is presently the chairman of the technical committee of the 1993 CSEG Convention. Another workshop is being organized for the Convention coming up May 4-6. The topic this…
Geophysics: The Potential and Limits for Reservoir Description and Monitoring
Robert J. (Bob) Graebner
Use of geophysics, particularly 3D seismic surface measurements, as an essential element for reservoir description has come into prominence in the last decade. This use has been driven by the shift from exploration to exploitation in many parts of the world. This occurrence is particularly widespread in the United States…
