    Title More EM myths and Old-fashioned Methods.

    SpeakerGreg Hodges, Senior Geophysicist at Sander Geophysics.


     

    AbstractThere 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.

    Title Deep Learning as an alternative to downward continuation filters for structural interpretation

    SpeakerJean-Philippe Paiement, P.Geo., M.Sc. – Director, Global Consulting - Mira Geoscience


     

    AbstractOftentimes when working with regional magnetic surveys from multiple sources, we encounter resolution continuity issues, which makes 2D interpretation more challenging. The loss in resolution of anomalies borders and lack of texture in the gridded data, can cause issues to the interpreter. This talk sets the basis of using currently available deep learning architecture to train a model for special resolution enhancement. 
    Recent advancement in image processing and deep learning have led to the development of neural networks capable of increasing images resolution using and adversarial learning strategy (Wang, X et al., 2018). In this deep learning model, available high-resolution grids with their low-resolution counter parts are used to train an encoder-decoder network to reconstruct the high-resolution from their starting point. Once the network is sufficiently trained it is then possible to apply it to upscale low-resolution images without existing ground truth high resolution counter part. This approach uses Generative Adversarial Networks or GAN’s, a relatively new class of machine learning frameworks designed in 2014 (Goodfellow, I. et al). A generator network is used to construct images that are then passed through a discriminator network which tries to discriminate between real images and fake images produced by the generator. Given a training set, this technique learns to generate higher resolution data with the same statistics as the training set. 
    Once the general model is trained on high-resolution/low-resolution pairs, it is possible to refine it to the area of interest and use it to upscale low resolution survey patches. This will help in refining anomaly edges and increase the accuracy of the structural interpretation conducted by the geologist. This approach is proposed as an alternative to the commonly used downward continuation filters used in the industry.

    KEGS-Québec :  Réunion Virtuelle 5-à-7 Géophysique et Remise des Bourses de la Fondation KEGS
    Date : 26-novembre, 2021 de 17h à 19h.

    Cher(e)s collègues et ami(e)s géophysiciens et géophysiciennes québécois(es) et franco-canadien(ne)s,
    L'année 2021 a été une autre année très différente pour nous tous, mais heureusement les choses reviennent petit-à-petit à la normale.

    À défaut de se rencontrer encore une fois cette année au déjeuner du KEGS-Québec ou dans le cadre d'un autre congrès, nous vous invitons à vous joindre à nouveau à un 6@7 Virtuel Géophysique.


    En même temps, nous ferons la remise des Bourses de la Fondation KEGS aux récipiendaires universitaires québécois pour l’année 2021.

    Ce sera une belle occasion de se voir le moment de conférences, de célébrer la future relève étudiante et de faire une petite santé de fin d'année, tous ensembles.  

    Cette année nous avons deux conférenciers : Pour débuter, M. Adrien Dimech, candidat au doctorat de l’UQAT, et le récipiendaire inaugural de la Bourse des Pionniers de la Géophysique Québécoise, nous fera une courte présentation sur sa recherche doctorale.

    Ensuite, notre conférencier principal sera M. Marc Boivin qui nous présentera sa conférence intitulée : « L’aimantation rémanente en exploration minérale».  


    Conférencier
     Marc Boivin MB Géosolutions
    Titre
     L’aimantation rémanente en exploration minérale

    Sommaire :
    Le phénomène de l’aimantation rémanente est connu depuis très longtemps, mais a souvent été considéré comme marginal du point de vus de l’exploration minière. Cependant, plusieurs gisements métallifères sont directement associés à réponses d’aimantation rémanente.Des liens directs peuvent être faits entre l’aimantation rémanente la mise en place de certains types de gisement métallifère et pourraient même servir d’outil en exploration minière. Cette présentation fait un survol rapide de ce concept à partir de réflexions personnelles et d’exemples..


    Biographie :
    L’auteur, M. Marc Boivin est géophysicien consultant avec MB Géosolutions depuis 2006. Il a travaillé comme chef géophysicien pour SOQUEM entre 1993 et 2006, géophysicien d’exploration pour WMC entre 1990 et 1993 et géophysicien de terrain pour Sagax Géophysique entre 1985 et 1990.M. Boivin a étudié aux études supérieures à l’École Polytechnique de Montréal en géophysique entre 1984 et 1985, après avoir complété un B.Sc. en géologie à UQAM en 1983. Il est membre de l’OGQ, PGO et APEGNB.

    Par la suite, comme l’année passée, nous espérons que vous pourrez rester en-ligne pour une réunion (virtuelle) entre amis(es).
    Joignez-vous à nous le 26 novembre prochain de 17h à 19h  ET. Le lien ci-dessous vous mènera vers la visio-conférence (ajoutez le à vos calendriers):
