1996 Current Research Symposium

The Department of Geology and Geophysics is again organizing a one-day Research Symposium on Monday, April 15, 1996. The Symposium will feature current work of students and faculty, and also offers an opportunity to viewDepartment facilities. Work will be presented through poster sessions, andabstracts will be compiled into a book which will be distributed to all participants.

The last Research Symposium, held in 1994, attracted over 100 geologists and geophysicists from industry, and featured 65 poster presentations by students. We looking forward to updating you on recent research and introducing the work of students and faculty who have since joined the Department. Look in next month's CREWES NEWS for more information on this event.

Planned Agenda:

8:30 - 9:00am: Registration in Earth Sciences Building foyer
9:00 - 9:10am: Welcoming remarks by Department Head, Dr. Ian Hutcheon
9:15 - 10:00am: Presentation of selected student paper
10:10 - 11:45am: Posters
11:45am - 1:30pm: Lunch and student awards presentation
1:30 - 2:30pm: Departmental laboratories and other facilities open for viewing
1:30 - 3:30pm: Posters

Blackfoot 3C-3D Processing

The 3C-3D survey from Blackfoot isbeing processed by Pulsonic Geo-physical and also by Sensor Geophysical. We expect to see final migrated stacks in March and are very encouragedby the quality of the data thus far.

Anisotropy Workshop Report

The 7th Annual International Workshop on Seismic Anisotropy was recently held in Miami, Florida. Drs. Jim Brown and Don Lawton and graduate students Michael Slawinski and Jennifer Leslie (Foothills Research Project) attended theWorkshop. Michael presented his work with Jim and Raphael Slawinski on "Ray tracing in layered, anisotropic media -comparison of traveltimes for synthetic and experimental results; traveltime inversion". Jim chaired the session on"Scaling, Resolution and Uncertainty" and also presented a paper on "A comparison of numerical and physical modelling of shear-wave propagation in orthor-hombic Phenolic CE" (coauthors: G. Rumpker and C.J. Thomson). Representingthe Foothills Research Project, Jennifer and Don Lawton presented work on "P-wave velocity anomalies induced by a variably dipping transversely isotropicthrust sheet." Participants reported difficulty adjusting to the 50 degrees F temperature difference between sunny Miami and frigid Calgary.

Visiting Student

Johan Guenver joins us at CREWES for a two month training period. Johan is from Angers, France, where he obtained hisBachelor of Science degree. He has a background in computer science and is currently studying Marketing and Management atthe Ecole Pratique des Dirigeants Commerciaux de France. While studying at the University of Calgary, Johan will be working on programming and management projects.

1996 Annual Sponsors Meeting

Plan now to join us at the Lodge at Kananaskis from November 3 to 5, for our 8th Annual Meeting The format will be similar to previous years, with an ice-breaker on Sunday evening and two days of technical presentations on Monday and Tuesday. We will send you more details later in the year.

Profile: Jocelyn Dufour

Jocelyn is currently in his second year of the M.Sc.programin Geophysics, under the supervision of Dr. Don Lawton. He is studying seismic data processing with an emphasis on refraction statics analysis for 3-C and Foothills (structural) seismic data. The research involves the computation of refraction statics using differential refracted arrivals analysis and Plus-time analysis. He is implementing his code in Matlab.

Jocelyn graduated from University Laval (Ste-Foy, Quebec) with a B.Sc. in geology. His interest in petroleum exploration was sparked by his participation in the Student Industry Field Trip (SIFT) in Calgary (May1993). He worked in seismic interpretation with Norcen Energy Resources Ltd. as a summer student in 1995. For two summers, Jocelyn did geological mappingin the Appalachian Mountains, and also spent one summer interpretating geophysical data for diamond exploration.

Jocelyn holds a scholarship from FCAR (Fonds pour la Formation de Chercheurset lšAide a la Recherche).

He has submitted an abstract, "Shear-wave refraction static analysis for P-Sdata", to this year's CSEG convention in Calgary.


Although this may seem a paradox, all exact scienceis dominated by the idea of approxmiation.
