An Evaluation of Ground Penetrating Radar for Imaging the Near Surface Examples from Contaminant Map
Don C. Lawton and Harry M. Jol
Ground penetrating radar (GPR) is becoming established as a new geophysical technique for imaging the near-surface. In this presentation, we assess GPR in terms of its application in the petroleum industry, and evaluate its capabilities for mapping a contaminated site near downtown Calgary and for delineating the internal geometry of…
3-D Survey Design by Computer
Mike Galbraith
3-D Acquisition requires careful planning. Laying out lines of receivers and lines of shots must be done with an eye to the expected results. Computer programs are now available to assist the geophysicist in this task.
... 3-D Survey Design by Computer
Mike Galbraith
oday's 3-D surveys can be large or small, laid in straight lines across deserts or tundra or along winding roads through forest and jungles. Because 3-D acquisition requires careful planning it is essential to analyze the complexities which naturally arise. Computer programs are now available to assist the explorationist with…
Pole Shooting
Rupert Goodhart
Surface shooting and other portable techniques were introduced to Canada to eliminate the impact of "dozing" wide seismic lines in beautiful and fragile terrain. The Foothills are not only a petroleum province with hydrocarbon resources in the many billions of dollars, but an area of scenic beauty without compare which…
1993 SEG Summer Workshop
Michael Enachescu
This year's SEG summer research workshop took place August 1-6, 1993, in Rancho Mirage, an exclusive golf and country resort situated in the southern California desert area. The day most of the participants arrived, the Palm Springs airport was shut down at 5 pm due to over-heating of the tarmac.
... 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…
