A Bayes’ Theorem Tutorial

BRIAN RUSSELL VICE-PRESIDENT, GEOSOFTWARE. BRIAN.RUSSELL@GEOSOFTWARE.COM   Introduction This tutorial is intended to illustrate the power of Bayes’ theorem using a straightforward seismic exploration example. This example will show how to evaluate the effectiveness of combining AVO attribute analysis with drilling results. As a tutorial, it is like many others used in the explanation of Bayes’ theorem, but instead of using examples like apples and oranges or white and black balls, I will use terminology that you can relate to as exploration geoscientists. Even with this relatively simple example, you will find Bayes’ theorem is not an easy concept to understand, [...]

CSEG Mentorship Program Professional Development Series

STEPHEN KOTKAS GEOPHYSICAL DATA BROKER, SIGMA EXPLORATION; MEMBER, MENTORSHIP COMMITTEE (CSEG FOUNDATION) STEPHEN.KOTKAS@SIGMAEX.COM SARAH GRANT GEOPHYSICIST, CENOVUS ENERGY; MEMBER, MENTORSHIP COMMITTEE (CSEG FOUNDATION) SARAH.GRANT@CENOVUS.COM The CSEG Mentorship Committee organized a professional development workshop on January 25, 2024 with Jilliane Yawney, in partnership with GeoWomen of Calgary. This in-person event was held in Calgary (at 715, 5th Ave SW) and the venue was graciously sponsored by Earth Signal Processing. The event was free to attend, included a delicious lunch, and had a great turn-out. With over 50 pairings of mentee’s and mentors, the Mentorship program continues to grow and achieve success [...]

An interview with Janis Rose

INTERVIEW COORDINATED BY SATINDER CHOPRA“Try and do things you enjoy”Janis Rose is a senior geoscientist with over 20 years’ experience in both exploration and development. She started off in the petroleum industry by joining Chevron Canada and remained a loyal employee for eighteen years, working on assets in western Canada, east coast offshore, and the Mackenzie Delta/Northwest Territories. This gave Janis a broad overview of seismic interpretation and prospect generation, as well as the associated risk and economics. Since 2017, she has been working at Cenovus Energy, and is using her insights and informed decisions towards advancing exploration and development.Apart from [...]

Intelligently Evolved to Create AI, eh?

ROD GARLAND CAGC MANAGER OF SAFETY & MEMBER SERVICES ROD@CAGC.CA Ever since man slithered out of the primordial soup disguised as a single-celled organism about 3 billion years ago, give or take a few millennia, he, she, or it has been greatly advantaged by change. Not the least of this change would have been the changing environment which had finally cooled the planet to a suitable temperature such that a mixture of chemicals and necessary elements could interact to create lifeforms that would embark on their evolutionary and competitive race into the future. Incidentally, hydrogen, oxygen and carbon were the [...]

CCS value written in a bowtie

LEE HUNT GEOPHYSICIST, CARBON ALPHA, LHUNT@CARBONALPHA.COM All aspects of a CCS project are tied back to risk management; value in the geosciences, including seismic, are directly related to their role in reducing project risk.   Summary Much of the world is looking to carbon capture and storage (CCS) to reduce anthropogenic carbon dioxide (CO2) emissions. The number of carbon storage projects under development has exploded - with over 200 currently proposed projects worldwide (Hauber, 2023). Geoscientists engaged in subsurface work on these projects are interested in providing the most value possible to these projects. But where is that value added? [...]

Bandwidth Extension of Seismic Data and its Impact on Seismic Unsupervised Facies Classification

SATINDER CHOPRA SAMIGEO, CALGARY, CANADA, SATINDER.CHOPRA@SAMIGEO.COM RITESH KUMAR SHARMA SAMIGEO, CALGARY, CANADA JOHN P. CASTAGNA THE UNIVERSITY OF HOUSTON, USA KURT J. MARFURT THE UNIVERSITY OF OKLAHOMA, NORMAN Abstract Bandwidth extension of seismic data is a desirable goal when the available data has inadequate frequency content to delineate thin beds, facies changes, and subtle faults. Though significant efforts are expended to preserve frequency content during processing of seismic data, processes such as multi-window statistical deconvolution, inverse-Q filtering, as well as time-varying spectral whitening, are not effective enough when the intervals to be characterized are below tuning. Consequently, methods have been [...]

Taking up the Mantle of Change: Re-establishing what binds us.

DENNIS ELLISON SENIOR PRINCIPAL GEOPHYSICIST, ASPENTECH AND PRESIDENT OF CSEG DENNIS.ELLISON@ASPENTECH.COM I am humbly writing this article with the mantle that comes with being the President of the Canadian Society of Exploration Geophysicists (CSEG). I am proud of the CSEG and consider it an honour to be a member. I grew up in Calgary and was surprisingly unaware of the Oil & Gas community. During my youth, geophysics held no significance for me - it could have been anything, as it didn't even register as a concept in my mind or a word in my vocabulary. However, as I entered [...]

Carbon Capture Canada Conference

DARREN KONDRAT GEOPHYSICAL CONSULTANT DARRENK@ROCKYVIEWGEOSERVICES.CA LUKE HARLOW-LAWRENCE B.SC., GEOPHYSICS The 2nd annual Carbon Capture Canada Conference – the nation’s only carbon capture, utilization, and storage convention - was held in Edmonton, Alberta. As the 2030 federal goals for emission reduction draw closer, collaboration and conversation around CCUS projects is crucial, and Carbon Capture Canada provided a space to connect. Bre Fox, Chair of Carbon Capture Canada, welcomed the session with an emphasis on a call to action, asking questions on best practices for our clean energy future. There were more than 100 exhibitors and over 150 industry leading speakers spread [...]
