Registration (Licensure) of Geoscientists in Canada: A National Perspective and Update

Gordon D. Williams

…Introduction The registration (licensure) of professionals such as doctors, lawyers, engineers and, increasingly, geoscientists in Canada is the responsibility of individual provinces and territories, under acts of their respective legislatures. These acts limit or restrict the practice of the professions to those persons who are registered (licensed) by autonomous, self-governing…

Rock Physics and 4D Seismic for Improved Oil Recovery

Dr. Amos Nur

…1997 SEG Spring Distinguished Lecture The worldwide volume of already discovered but unrecovered oil is by now enormous – on the order of (according to some) the oil that still remains to be discovered. On average, only 25% of discovered oil is being recovered in the world, whereas 65% to…

Geostatistical Depth Mapping: Integration of Seismic Times with Well Tops

David L. Garner

…A perpetual exploration problem is to produce depth maps useful for the goals of both geologists and geophysicists and to accurately derive a target depth estimate at a proposed well location. A case history whereby seismic horizon times and well tops are combined to estimate depth using the collocated co-kriging…

Using Technology for E&P Success – the Practices of the Leaders

George Eynon

…The western Canadian petroleum exploration and production industry has evolved considerably since the oil price shock of 1986 and the gas price shock of 1990-92. Early adjustments focused on reducing G&A. The second, current phase has an operating emphasis. The primary goal is to meet shareholder objectives - whether those…

Migration Operator Aliasing and its Effect on Interpolation

Peter Cary and Bill Goodway

…Introduction The controversial topic of 3D spatial sampling and its impact on the final seismic image has generated several articles in the last few years advocating coarsely sampled acquisition geometries (e.g. Neidell, 1994; Goodway & Ragan, 1996). On the other hand, Vermeer (1995) has advocated a fine, "symmetric" sampling geometry…

Pre-stack Inversion: Evolving the Science ofInversion

Rick Wallace and Roger Young

…Over the past 2 decades seismic inversion, ostensibly the process of deriving rock properties from seismic measurements, has evolved significantly. The early methods of recursive inversion converted seismic traces to well log traces providing a measurement of the "pseudo acoustic impedance". The acoustic impedance could also be expressed as "pseudo-acoustic…

One Interpreter’s Most Excellent Adventure

Jan Dewar

…Synthetic seismograms are a common tool in geophysical interpretation. They make use of the simple idea of correlating known subsurface information from a well with seismic data recorded on the surface. But sometimes a synthetic seismogram does not match a seismic section very well, and what should be a straight…

Geostatistical Reservoir Characterization of A Canadian Reef Or The Use and Abuse of Geostatistics

Keith Hirsche, Larry Mewhort, Jan Porter-Hjrsche and Rick Davis

…Abstract Geostatistical methods are becoming widely accepted in reservoir characterization. The appeal of these techniques is the ability to integrate diverse types of information, including seismic data, into a consistent subsurface model. An added benefit of geostatistics over deterministic reservoir description is the ability to assess uncertainty in the modelling…
