Cascaded Dipole Filters: Extending the Limits of Seismic Resolution

Penny B. Colton and Atul Nautiyal

…Introduction In the challenging world of mapping thin stratigraphic targets, a geophysicist may choose to try a tactic for increasing resolution, particularly if it is simple, quick and has a known effect. The dipole filters described below, with either even or odd iterations (zero or 90 degree phase shift), can…

Mining Exploration: A New Frontier for the Canadian Seismic Industry

David W. Eaton, Bernd Milkereit, Matthew Salisbury, Erick Adam and Jianjun Wu

…Introduction Like the oil and gas industry, the mining industry is a cornerstone of the Canadian economy, with production of non-fuel minerals in the order of $12 billion annually. With a few notable exceptions (e.g., the spectacular Voisey Bay nickel-cobalt discovery in Labrador), the Canadian mining industry is looking progressively…

Surprises in Glauconitic Incised Valley Channel Exploration Using 3D Seismic: Risks and Opportunities

Marilyn J. Mawdsley, Alma L. Eamer and Brian A. Zaitlin

…Summary Exploration risks commonly associated with the seismic definition of Lower Cretaceous incised valley channel sandstone (IVCS) reservoirs are: I) the distinction of shale versus sandstone and 2) ambiguities caused by seismic interference from both the underlying Paleozoic unconformity and younger Mannville coals. A post-drill review of two wells drilled…

The Integration of Logs, Borehole and Surface Seismic

Dick Ireson

…The calibration or AVO Walkaway technique, where the downhole geophone array is placed just above the reservoir, is gaining acceptance as a tool for evaluating the full elastic response of the reservoir local to well locations. It may also be used to evaluate the velocity anisotropy of the layers in…

The Blackfoot Seismic Experiments: Broad-Band, 3C-3D, and) 3-D VSP Surveys

Robert Stewart, Robert Ferguson, Susan Miller, Eric Gallant and Gary Margrave

…Introduction A number of paths could lead to fundamental advances in seismic exploration. These include: broadening of the recorded frequency band, use of the full 3-D elastic properties of the Earth, and 3-D borehole images. We would like to extend the recorded seismic frequency band (both up and down) to…

Geoscientist Registration in Ontario

…Geoscientists in Ontario are trying (once again) to achieve professional registration. This time, the chance of success appears to be significantly greater. As of March 10, 1996, the Association of Geoscientists of Ontario was formed, following from the Committee for Professional Registration of Geoscientists in Ontario. The aim of this…

The Evolution of Shallow Marine Data Acquisition in Canada

Peter Kitson

…Prior to 1984, shallow marine exploration in Canada was almost non-existent. Most recording systems were not readily adaptable for working on water. There were no marine cables. Airguns had been in Canada for some time, but were used primarily for infill coverage and testing. Some equipment had been brought in…

Applied Seismic Inversion for Estimating Earth Models in Depth

Oz Yilmaz

…Processing and inversion, both are intended to estimate earth models from seismic data. Nevertheless, they differ in one fundamental respect - the output domain. Processing yields an earth model in time, whereas inversion yields an earth model in depth. A way to judge accuracy of an earth model derived from…
