The Seismic Signature of Meteorite Impact Craters

M.J. Mazur, R.R. Stewart and A.R. Hildebrand

The sky is falling! The sky is falling! Well, not usually, but Chicken Little is occasionally right. There are times when stones and ice do fall from the sky. And if they’re big enough, they’ll excavate major cavities on impact. After erosion, infilling, and burial, these impact craters can become…

Izmit – Turkey Earthquake August 1999

Turgay Ogut

Earthquakes are the worst of the natural disasters. Because of their overwhelming power and the damage that they cause, men have been studying them for centuries. The first earthquake observatory was established during the East Hun Dynasty of China in 132 AD. The first (?) seismologist Heng Chang used a…

An overview of luncheons offered at GeoCanada 2000.

Using In-Situ Stress and Rock Mechanical Properties to Plan Your Best Well Trajectory with STABView™

Pat McLellan and Chris Hawkes

Advanced Geotechnology are the developers of STABView™, a Windows-based software package for evaluating borehole stability, lost circulation and sand production risks for vertical, deviated and horizontal wells in a wide variety of geological settings. In many sedimentary basins, especially in tectonically deformed strata or deep offshore settings, and those possessing…

Internet Delivery of High Resolution Aerial Ortho-Imagery

Larry Herdand and John Welter

The planning, organization and management of hydrocarbon exploration and exploitation operations requires accurate, complete and current maps illustrating the topography and surface features whether man made or natural. This information is invaluable for seismic planning and operations, well site planning and facility engineering. All aspects of surface activity from planning…

International Hot Spots 2000

Gordon Cope

The preceding year has brought a raft of changes to the international exploration picture; the CSEG Recorder looks at some of the hot-spots, not-spots and up-and-comers for the year. Since early 1999, the price of oil has almost tripled, but seismic exploration has lagged. “It’s better this year, the only…

Static Corrections for the 21st Century

Mike Cox

Static corrections are routinely applied to almost all surveys. In the past, the main emphasis has been for the computation and application of datum and residual static corrections on land and transition zone surveys. For marine surveys, static corrections are used to adjust the data to a sea-level datum with…

Moving Up the Processing Ladder

Gordon Cope

Recent advances in geophysical workstation hardware and software allow interpreters not only to view pre-stack data, but also to manipulate it. Are the days of processing numbered?

Fractured Reservoirs: Software and workflow advancements in fracture and fault prediction, characterization, and connection to reservoir modeling

David Richards

In Canada and many exploration and production areas worldwide, a better understanding of fractured reservoirs is essential to efficient exploration and production. New enhancements in software allow improved prediction and modeling of fractured reservoirs. Combined application of structural restoration software (3DMove), an associated fracture generator based on geologically oriented rules,…

3-C Digital Sensor

Peter W. Maxwell

For the last 60 years, seismic surveys have relied on a very simple but durable sensor – the geophone. Despite its long record of success, recent developments may ultimately make the geophone obsolete. Input/ Output, Inc. have developed a new 3-C digital which measures acceleration rather than velocity.

ARAM24 Seismic Recording Systems

Gary James and Valentin Poncos

Perhaps from the first time that a geophone was planted in the ground and the raw seismic data was handed from a recording engineer to a "field computer" we have heard the refrain, "Oh, they'll fix it in the processing!"

The Internet as a Geophysical Tool

Rob Vestrum

The Internet has gone from fad and fashion to an integral part of the way we do business. Our culture communicates via email and gets informed and entertained on the web. How is the high-tech culture of the geophysical community utilizing this resource?

Foothills: The Future for Exploration

Andrew C. Newson

The Calgary exploration industry is faced with the major challenge of finding new gas reserves and developing them in a cost effective and sustainable manner to meet growing consumer demand. Natural gas consumption in North America is expected to climb from the current 25 Tcf a year to 30 Tcf…

The Perfect IT System

Gordon Cope

Imagine a computer system that increases reserves, lower costs, and maximizes the efficiency of every single asset you possess. It is Monday morning, and the board-of-directors is calling for more profits. Now. With a flick of a mouse, you call up sales at the gas pumps and note with satisfaction…

GPS in the Context of Geomatics Engineering and Applications to Geophysical Exploration

Dr. G. Lachapelle

Geomatics engineering is an emerging key information technology of the 21st Century which deals with the acquisition, modeling, analysis and management of geospatial data. Its concepts and use for a variety of applications, including exploration geophysics, are first reviewed. The fundamental role of positioning in georeferencing data is described. GPS…

Beyond the Horizon II

Gordon Cope

As the new millennium dawns, it is natural to focus on the future and what it holds for exploration geophysics. In the second of a two-part series, The Recorder looks at some exciting new research in the interpretation sector that will have an impact on the profession a decade down…

Dynamic Range and the Seismic System – What Has Been Accomplished and Where Must We Go

Norm Cooper

The combination of earth absorption and limited dynamic range results in limited recoverable bandwidth from our seismic data. Limited bandwidth means limited clarity of our images of the subsurface. Therefore, much emphasis has been placed on improving dynamic range in past years. Through to the end of the 1980’s, one…
