The Prairie Meteorite Search

Alan Hildebrand, Dan Lockwood and Andrew Bird

…Meteorites have been accumulating on the Canadian land mass since the end of the last glaciation, approximately 10,000 years ago. The current rate of fall for meteorites >100 g mass (surviving to the ground) is ~27 per year per 106 km2. With a 10,000 year integration time, and presuming that…

Tectonic Evolution of the East Coast of Canada

Keith Louden

…Introduction The East Coast of Canada is generally divided into three regions: the Nova Scotian margin in the south, the Newfoundland margin in the centre and east, and the Labrador margin in the north (Figure 1). These margins formed during the past 200 million years as the supercontinent of Pangea…

Tectonic Evolution of the Canadian Beaufort Sea – Mackenzie Delta Region: A Brief Review

Larry S. Lane

…Abstract The Canadian Beaufort Sea continental margin is probably the best known segment of the Arctic Ocean margin, based on the interpretation of multiple datasets defining the deep crustal architecture, regional structural trends and the temporal-spatial tectonic evolution. Of 53 oil and/or gas discoveries, most are trapped in structures formed…

The majority of his experience comes from working with conventional survey where he has been the senior surveyor responsible for crews in the field. He places…

On Seismic Waves in Linearly Elastic, Anisotropic and Nonuniform Continua

Michael A. Slawinski

…Introduction Most sedimentary rocks are anisotropic. Most sedimentary basins are nonuniform. Consequently, exploration seismologists benefit from knowledge of these properties. This knowledge provides us with rock-physics information and also enables us to account for the effects of anisotropy and nonuniformity on seismic imaging. Anisotropy and nonuniformity are conveniently studied in…

Discovery of Ring Faults Associated with Salt Withdrawal Basins

Steven J. Maione

…The Jurassic Louann salt has played a dominant role in influencing the structural and depositional history of the East Texas Basin. Petroleum traps within the basin exhibit structural and stratigraphic elements influenced by salt tectonics, particularly during the Jurassic and Cretaceous periods. Petroleum reservoirs in East Texas Basin include the…

Integrating Coherence Cube Imaging and Seismic Attributes

Satinder Chopra

…Coherence Cube™ Imaging1 Coherence Cube imaging essentially generates a cube of coherence coefficients (from the input 3D seismic data volume) that portrays faults and other stratigraphic anomalies clearly on time or horizon slices. These images show up distinctly, depicting buried deltas, river channels, reefs etc. Traditional seismic time slices are…

Coals and their confounding effects

Mike Perz

…Pending Introduction If someone were to compile a list of “usual suspects” most often blamed for processing artifacts observed on Western Canadian Sedimentary Basin (WCSB) seismic sections, high amplitude coal reflectors would be found somewhere near the top (right alongside other well-known culprits such as ground roll, anisotropy, inadequate spatial…

Examining Due Diligence & Liabilities — CAGC Symposium

John Bertsch
