Introducing our new Chief Editor

2023-06-01T23:11:24-06:00

NILANJAN GANGULY CHIEF EDITOR, CSEG RECORDER,CHIEF GEOPHYSICIST, CANACOL ENERGY, NGANGULY@CANACOLENERGY.COM Hello everybody, I am Nilanjan Ganguly, your new Chief Editor for the CSEG Recorder. I feel honoured and privileged to serve you all in this role. First of all, I would like to thank Brian Schulte, our outgoing Chief Editor for his outstanding job over the past six years. Brian has set a very high standard for this role and his will be large shoes to fill in. However, we do have a very talented and dedicated team of Technical Editors to help me out; and so we are all up [...]

Future of oil and gas through technology, leadership, and change management (Digitalization)

2023-05-25T23:28:17-06:00

BRIAN WM. SCHULTE STUDENT SPROTT SCHOOL OF BUSINESS – CARLETON UNIVERSITY CEO SCHIEFER RESERVOIR CONSULTING, BSCHULTE@SCHIEFER-RESERVOIR.COM Abstract In today’s industry, many say geophysics is not needed because: There are too many wells, so it is easy to map the subsurface. Seismic does not have the resolution to see the thin sands. Have not had a lot of success with geophysics in this play. This sentiment is further expressed when artificial intelligence (AI), predictive or prescriptive analytics, or machine learning (ML) are discussed, with many feeling geophysicists (geoscientists) will soon be replaced with AI or ML. Despite what is being said, [...]

Geophysics at the University of Alberta: A longstanding and vibrant tradition

2023-05-19T12:31:41-06:00

MIRKO VAN DER BAAN DEPARTMENT OF PHYSICS, UNIVERSITY OF ALBERTA, EDMONTON, ALBERTA, CANADA. MIRKO.VANDERBAAN@UALBERTA.CA Introduction Geophysical research at the University of Alberta has a long and rich history, starting in 1954, investigating both applied and fundamental questions such as: Why do the Earth and planets have magnetic fields? Can we forecast earthquakes? What was the climate like in the past? How did plate tectonics form the Rocky Mountains? How do we locate hydrocarbons and other resources underground? Does hydraulic fracturing cause earthquakes? Is geothermal energy an option for Canada? What happens to CO2 stored underground? The early years: The 1950s [...]

Chief Editor’s Farewell Column

2023-06-01T13:13:10-06:00

BRIAN SCHULTE CHIEF EDITOR, CSEG RECORDER, SCHIEFER RESERVOIR, BSCHULTE@SCHIEFER-RESERVOIR.COM In July 2017, Nicole Willson, former Chief Editor of the Canadian Society of Exploration Geophysicists (CSEG) RECORDER, approached me about myself replacing her as the Chief Editor of the CSEG RECORDER. I committed to Nicole to do it for just two years, but I have done it for almost six years now. It has been challenging at times, especially during Covid and the lockdowns, but it was always important to me that the committee collaborated and worked together. Serving as the Chief Editor has been a privilege, rewarding and a career [...]

The Relationship between AVO and Petrophysics

2023-05-05T13:18:20-06:00

DAVID GRAY SVP INTEGRATED STUDIES, GEOMODELING TECHNOLOGY CORP, FDAVID.GRAY@GMAIL.COM Purpose The main purpose of this article is to provide geoscientists with one source which uncovers the connection between pre-stack seismic gathers and the petrophysical properties that cause amplitude versus offset (AVO) variations in them. There are many seismic AVO equations in the literature, all parameterized differently, e.g., Shuey (1985), Smith and Gidlow (1987), Verm and Hilterman (1994), and Gray et al (1999). This paper attempts to reconcile these parameterizations by presenting all of these existing equations using common parameters which are defined in Appendix A. Table 1 lists all the [...]

2022 CSEG Scholarship Report and Winners

2023-04-20T23:08:16-06:00

STEVE QUAN, CHAIR LORI BARTH, SENIOR TRUSTEE STEPHEN KOTKAS, JUNIOR TRUSTEE Every year the CSEG Scholarship Committee awards scholarships to deserving candidates in continuing education across Canada. In the 2022 scholarship year, over 80 high-quality applications were received from across Canada and 15 scholarships of $2,000 were awarded. In order to qualify for a university student award, students must be enrolled at a Canadian university in an academic program leading to a career in exploration geophysics. Scholarships are awarded on the basis of academic performance, financial need, interest in geophysics and extra-curricular activities. In 2012, the Foundation introduced a new [...]

Canadian Federation of Earth Sciences Brings Canadian Geoscience Organisations Together

2023-06-01T13:13:58-06:00

RACHEL T. NEWRICK, PH.D. RACIAN VENTURES, RACHEL@RACIAN.CA MIKE HALL MIKE.HALL@GEOVECTRA.CA TOM SNEDDON MARMOT RESEARCH INC, TOM@MARMOTRESEARCH.CA RON LARSON RONLARSON1210@GMAIL.COM Abstract The Canadian Federation of Earth Sciences (CFES) is funded, in part, by your CSEG membership fees. This article provides information on what the CFES is, does, and how CSEG members benefit from it. Introduction What do Canadian geophysicists, geologists and geotechnical professionals have in common? (No, this is not the start of a bad joke.) They are all represented by the Canadian Federation of Earth Sciences (CFES), an umbrella organisation of Canadian earth science societies. [...]

An Interview with Cheran Mangat

2023-05-04T10:29:13-06:00

“Strive to be ambitious without forsaking your principles…” INTERVIEW COORDINATED BY SATINDER CHOPRA Cheran Mangat is a geophysicist who has worked in North America and international arenas. She is a highly motivated individual who likes to use geophysical tools and technologies to make significant contributions to the bottom line. Having worked as an explorer, geophysical interpreter, development geophysicist, and stratigrapher, she has seen it all. On being asked for an interview, Cheran was quite supportive, and that led me to ask her a wide range of questions. The following are excerpts from the interview. Cheran, please tell me something about [...]

AVO, Seismic Inversion, Machine Learning and Predictive Modelling and the Economics of the Play – New Age for Oil and Gas Exploration

2023-03-30T16:43:21-06:00

BRIAN WM. SCHULTE SPROTT SCHOOL OF BUSINESS – CARLETON UNIVERSITY / SCHIEFER RESERVOIR CONSULTING, BRIAN.SCHULTE@GMAIL488.COM DAVID GRAY GEOMODELING TECHNOLOGY CORP. SENIOR VICE PRESIDENT INTEGRATED SOLUTIONS, DAVID.GRAY@GEOMODELING.COM RENJUN WEN GEOMODELING TECHNOLOGY CORP. CEO, RENJUN.WEN@GEOMODELING.COM   Abstract Proxy modelling using seismic attributes significantly speeds up our understanding of what is going on between wells, adding substantially to the value that geoscience brings to our businesses. One of the most valuable uses of seismic data is to extract fluid and lithological information for reservoir characterization. Amplitude versus Offset (AVO) analysis and seismic inversion (deterministic or stochastic) are valuable tools for doing this. To [...]
