KEGS May Talk
Our next KEGS talk is happening May 10th at 4:00 PM EDT and will be hosted exclusively online.
Title: Application of Magnetotelluric in Geothermal Exploration
Speaker: Fateme Hormozzade
Date: Tuesday May 10th at 4:00 PM EDT
Abstract: Interest in geothermal exploration as an alternative source of energy is rising around the world as well as in Canada. Mapping structures of a geothermal reservoir is a necessary task to understand the fluid flow regime and viability of the reservoir. Magnetotelluric (MT) methods, are a subset of electromagnetic (EM) exploration techniques and are commonly used in geothermal studies. An audio-magnetotelluric (AMT) survey was conducted to explore for shallow geothermal resources in the Garibaldi Volcanic Belt, Canada, the location of which has the highest geothermal potential in Canada. In this talk, the potential geothermal reservoir at the Mount Meager Volcanic Complex (MMVC) will be reviewed. A detailed near surface electrical resistivity model of the MMVC region will be presented to 3-D image the reservoir zones accounting for the steep mountain topography. The results will support the broader goals of reducing the economic risks of geothermal exploration in the Garibaldi Volcanic Belt.
Bio: Fateme is a Ph.D. candidate in geophysics at Carleton University. She earned her B.Sc. in mining exploration engineering in 2014 and M.Sc. in petroleum exploration engineering in 2016 from the University of Tehran. After her M.Sc. studies, she gained 2+ years of work experience in a consulting company as a petrophysicist, studying petrophysical data and well logs of different reservoirs. She is currently involved in the Garibaldi Geothermal Volcanic Belt Assessment Project with the Geological Survey of Canada and is a teacher and research assistant at Carleton University. Her PhD thesis focus on the use of magnetotellurics to define shallow crustal fluid systems and geothermal reservoirs, insights from Garibaldi Volcanic Belt, BC, Canada.
KEGS is excited to announce a mini symposium focused on the electromagnetic (EM) method is planned for Saturday June 11th 2022. It will be held in person in Toronto, Canada the weekend preceding the Prospectors and Developers Association Convention. A social event will follow the symposium.
Electromagnetic (EM) methods have been a mainstay in exploration geophysics for over 50 years and continue to be a vital tool in applied geoscience. As EM systems have increased in power, complexity, and resolution jointly with vastly improved data processing and visualization tools, their application has extended well beyond the bump-hunters of old. The mini symposium aims to provide a snapshot of recent advances and applications of the EM method to geoscience problems.
The event will comprise a series of invited and solicited talks. At this time, KEGS is soliciting abstract submissions for a limited number of talks on the following topics:
Short abstracts (maximum 400 words) are due Friday, May15th, 2022. Please click here to submit your abstract, with "KEGS 2022 EM Mini Symposium Abstract" in the subject line.
Due to the short advanced notice of the call for abstracts, authors are encouraged to submit previously prepared talks.
The full schedule, pricing and registration will follow in a dedicated bulletin announcement.

Abstract: There are a few myths about EM held by many people that deserve study. Some of them are a result of limited experience with either time or frequency domain EM, or limited experience with multiple geological environments. Other misconceptions come from thinking that the two different mathematical models, time domain and frequency-domain, make things happen differently in the earth. Don’t ever think that the model defines the earth – it only attempts to imitate it.
Are time domain EM and frequency domain EM the same thing, or different? The answer is: “Yes”. The earth is not frequency domain. The arrow of time is not oscillatory. But it is important to recognize that what you will see from the earth depends on how you look at it. The nature of the response depends on how you energize the earth and how you measure the response.
Debunking other myths: Current rings propagate downward with time, but that doesn’t always mean that depth correlates to time of the response. Calculating new parameters from the same data is not adding new information. B-field from a coil is not really B-field. In-phase is real, but on-time is not in-phase. Bandwidth is about more than electronics. FDEM has IP effects. Levelling EM data damages the EM data quality.
Sometimes a pencil and paper (and your brain) can do a better job of modeling than the best computer.
Biography: Greg Hodges is a Senior Geophysicist at Sander Geophysics. Since 1980 his career has included most types of mineral exploration geophysics, with a strong concentration on electromagnetic methods. His career experience has been relatively equally divided between time-domain and frequency-domain EM, and between airborne and ground (including borehole). He's worked as a ground geophysical contractor, in junior and major mining companies, and (for the last 26 years) for airborne geophysical survey companies in R&D and applications development. Along the way he's had the good fortune to do development work with some of the leading practical experts in both time- and frequency-domain EM.
KEGS extends condolences on the passing of Bob Middleton.

MTNet webinars on EM:
Every second December, The Mineral Exploration Research Centre at Laurentian University presents a modular course on Exploration Geophysics. This year the course will be held December 8-17 in the Executive Learning Centre, room FA-386 of the Fraser building on Laurentian’s Sudbury campus. The course can be taken by graduate students for credit towards their degree programs, or by professionals, in which case it can be counted towards the hours required for continuing education by professional registration organizations like the PGO. This year, professionals can sign up at a reduced rate if they participate in the lectures remotely and on-line.
The course is intended for geologists and geophysicists and will cover all aspects of geophysical methods: theory, instrumentation, acquisition, processing, display and interpretation. The methods covered and the case histories presented will be focused on mineral exploration.
More details about the course and links to a brochure and a registration form can be found here
