An Overview of Digital Optical Disks
Graham Irving
With the explosion of CD Audio and CD-ROM discs today, most people are aware of optical disks and very likely use some form of optical disk technology, whether it be a home CD Audio player or a 2 Terabyte optical disk jukebox. Optical disks are currently making a significant impact…
Data Archival, Storage, and Distribution for the 1990’s and Beyond
Garth Paterson
This article is being written in response to a growing need for data managers and explorationists to gain information regarding the storage of digital seismic field and stack data on optical disk. There are two distinct areas involved in this storage, one is the long-term archive of the data, the…
Swan Hills Unit #1: Adding Value with Seismic Through Reservoir Delineation and Characterization
Doug Uffen and Rick A. Wallace
The Swan Hills Unit #1 lies approximately 200 kilometres northwest of Edmonton, Alberta, Canada along the trend of several long-standing producing fields from the Swan Hills formation. Home Oil is the operator of Swan Hills Unit #1 with approximately 18% working interest. The field was discovered in 1957, two months…
Seismic Parameter Design: in a Nutshell
A. Easton Wren
The diverse range of modern seismic activities precludes the possibility of a "jack-of-all-trades" geophysicist. Bridging the practical and technical gaps between acquisition and processing with modelling and interpretation is more elusive than ever, even with powerful multi-purpose work stations. Competence in one area of activity may simply be the conditioner…
CSEG/CSPG ‘94 Exploration Update
Neil Rutherford
The opening session of the joint CSEG/CSPG Exploration Update convention held in Calgary in May consisted of three panel sessions. Prominent speakers from a variety of Calgary based companies were invited to present their views on three separate subjects. The session attracted about 1000 convention registrants eager to hear the…
CGU Annual Meeting
J.B. Merriam
The Canadian Geophysical Union met in Banff, Alberta for its twentieth annual meeting May 14 to 18, 1994. One hundred and seventy six papers were presented in twenty one sessions. There were several new sessions this year including porous media-rock physics, marine geophysics, and global change.
... Lithoprobe Crustal Seismic Profiles in Central Alberta: New Reflections on the Evolution of the Albe
Gerald M. Ross, David W. Eaton, Bernd Milkereit, and Ernest R. Kanasewich
The crystalline basement beneath WCSB (Western Canadian Sedimentary Basin) is composed of crustal domains delineated on the basis of aeromagnetic signatures and U-Pb zircon geochronology of drill core recovered by the petroleum industry. Using analogies from the Canadian Shield, the mosaic of crustal domains is inferred to have formed during…
A Recommended Approach for Storing Field Data on CD-ROM
Lain Eng
CD-ROM technology is poised to become the worldwide medium of choice for information distribution and storage. CD-ROMs will become the floppy disks of the future. CD recorders (CD-Rs) will be as common place as an office photocopier.

... The Seismic Wavelet, Well Ties, and the Search for Stratigraphic Traps
Anton Ziolkowski
In most mature hydrocarbon provinces it is estimated that 40 per cent of the oil is found in stratigraphic traps, which are often very difficult to identify on seismic data directly. I suggest that the difficulty is caused by three related problems; deconvolution, multiple removal - especially in marine data and well ties.…
Ground-Based Magnetic Horizontal Gradient Intensity and Radiometric Surveys, a Cost-Effective Hydrocarbon Exploration Tool: Three Case Histories in Western Canada
Leonard A. LeSchack
Three case histories are discussed where ground-based magnetic horizontal gradient intensity (HGI) and radiometric (RAD) exploration surveys have been used effectively in Western Canada.
... The Progress of Geophysical Reservoir Description at Hibernia
Gary Taylor and Denis Couturier
Hibernia is located at latitude N. 46°44', longitude W. 48° 46' on the continental margin of the North Atlantic Ocean. Water depth is 78 metres, deepening east of the field as the Grand Banks of Newfoundland descend to the abyssal plain. The local marine environment is severe with storms, 20…
Ricker, Ormsby, Klander, Butterworth – A Choice of Wavelets
Harold Ryan
Commercially available software used to generate synthetic seismograms gives the geophysicist a choice of up to four types of standardized wavelets as well as the option of a user-defined wavelet. This review article will summarize the characteristics of these wavelets, illustrate the shape of the wavelets and their frequency spectrum…
The Future Role of the Seismic Method in Petroleum Exploration
S. Rutt Bridges
Experts from a variety of fields have predicted a revolution in computational power within the next five years. It is now apparent that we will soon have desktop Cray Y-MP equivalents and parallel machines readily available as network compute servers with teraflop performance. In addition, we will have the capability…
Sudhir Jain
Barbara Young
A cornerstone in the geophysical research and development field in Calgary for the last 20 years, Sudhir Jain, will be closing his company, Commonwealth Geophysical, at the end of June and moving on to other things. Sudhir's contribution to the geophysical community, not only in new software and techniques for…
C.S.E.G. Annual Meeting & Awards Luncheon
CSEG Executive Committee
The CSEG Annual Meeting was held March 15th, 1994 at the Westin Hotel. A Very Successful lunch time Awards Presentation and Business Meeting as well as a presentation on Earthquakes near Fort St. John. B.C.. was enjoyed by all in attendance. Several Societies within our industry were represented.
... C.S.E.G. Geophysical Workstation SEGY Standards
Doug Bath
With the proliferation of geophysical workstations in the industry it was felt by several members that the standards for SEGY stack data should be re-examined and if necessary brought up-to-date. Accordingly a committee was formed to discuss standards for geophysical workstation SEGY data formats. The following is a summary of…
Workshop on Problems with Phase
Stewart Trickett
On the afternoon of May 6, 1993, the final day of the annual convention of the Canadian Society of Exploration Geophysicists, a workshop entitled "Problems with Phase" was held at the Calgary Convention Centre. It produced a fascinating look at a subject which, despite its longevity, continues to present major…
Optimization Methods for Prestack and Poststack Migration (Migration without Migraines)
Larry Lines, Andrew Burton and Han-xing Lu
Increased efficiency of finding and developing hydrocarbon resources while reducing the environmental impact through geophysical technology is critical to the future of the petroleum industry. This technology must remotely determine rock-fluid property characteristics, their geometry, and changes over time. In reviewing advancements in exploration seismology, three component 3-D seismology stands…
