Geophysical Inversion Workshop and Summer School: A Big Success

Peter Cary

…The 2nd Geophysical Inversion Workshop and Seismic Imaging Summer School took place in August this past summer on the University of Calgary campus. This extremely successful meeting was enjoyed by about 80 attendees at the workshop and about 50 registrants in the summer school. Dr. Gary Margrave, the main organizer…

Non-first-break technology to remove effects of shallow velocity anomalies

Emil Blias

…As was analytically shown in the first paper (Blias, 2006a) shallow velocity anomalies can cause large lateral variations in stacking velocities. Non-removed shallow velocity anomalies (SVAs) can reduce the quality of the post-stack image and create time distortions in seismic horizons. A conventional approach to deal with SVAs utilizes first…

An Interview with Oz Yilmaz

…Oz, let’s begin by asking you about your early education and your work experience? I received my Bachelor’s of Science Degree in Geology with Geophysics Option from University of Missouri-Rolla in 1970. During my undergraduate years I realized that I am more interested in the engineering and mathematical aspects of…

An Interview with Jeffrey Yarus

…Jeffrey let me start by asking you about your educational qualifications and your work experience. I began my college career at the College of Wooster in Ohio, outside of Cleveland, where I was born. I majored in geology; that was from 1969 to 1973. During that time I also spent…

…Recent events have signaled the end of an era in the Canadian seismic industry. First, in May of this year, Geo-X Systems Ltd. sold its processing division to Divestco Inc. Then in early September came the announcement that CGG would be purchasing Veritas DGC. To many, these two companies represented…

Expert Answers

…Question 1 Inelastic attenuation in seismic data is frequency dependent (higher frequencies getting preferentially absorbed) and increases with traveltime, altering both the amplitude and phase of the data. While processing for AVO analysis, attempts are made to remove the effect of the many factors that influence AVO response, so that…

An example of a fully integrated Reservoir Characterization project utilizing well data, fluid substitutions, elastic modeling, production history, seismic and AVO attributes

Brian Schulte

…AVO has played a significant role in exploration over the last 20 years. However, the use of amplitudes as a direct hydrocarbon indicator is still not as reliable as desired. On the other hand experience demonstrates some of the issues needed to be addressed exist within the seismic data itself.…

The Future of Interpretation Software

Doug Paul

…Introduction The Canadian oil and gas industry has changed significantly over the last ten years. Soaring hydrocarbon prices combined with the emergence of trusts and small exploration companies have changed the landscape of the energy sector. As the petroleum industry becomes even more competitive, a premium is placed on the…

Preliminary Seismic Interpretation and Maps for the Paleogene-Neogene (Tertiary) Succession, Orphan Basin

Renee Burton-Ferguson, Michael Enachescu, Rick Hiscott

…Introduction The Orphan Basin, located offshore Newfoundland and Labrador, is one of the largest under-explored basins along the eastern Canadian Margin. With large 3D seismic surveys executed in 2004-2005 and a deepwater well planned for 2006, the basin has become the new focus area for hydrocarbon exploration in Atlantic Canada.…

Time-Frequency Polarization Analysis and Filtering

Rob Pinnegar

…Introduction Most of the “traditional” methods of polarization analysis and polarization filtering operate entirely in the time domain, or entirely in the frequency (or Fourier) domain. Unfortunately, both approaches have major limitations. Time-domain methods often have difficulty dealing with overlapping events that have different frequencies; and frequency-domain methods can run…

Curvature attribute applications to 3D surface seismic data

Satinder Chopra and Kurt Marfurt

…Summary Identifying subtle faults at or below the limits of seismic resolution and predicting fractures associated with folds and flexures is one of the major objectives of careful seismic interpretation. With the common use of 3D seismic in the late 1980s, 1st derivative based horizon dip magnitude and dip azimuth…
