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

Speaker: Jean-Philippe Paiement, P.Geo., M.Sc. – Director, Global Consulting - Mira Geoscience


 

Abstract: Oftentimes 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.

Modular course on Exploration Geophysics

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

Title:  Yaouré Gold Mine 3D seismic case history and recent hard rock processing and interpretation
developments
Speaker: Andy Dyke
Authors: Andy Dyke, Kevin Jarvis and Greg Turner

Abstract: 3D seismic reflection is gaining acceptance as a tool for accelerating the discovery of additional resources within mineralized environments. In this talk we will show how this is being achieved at the Yaouré Gold Mine in Côte d’Ivoire. In addition, we will show some of the new approaches that are being applied both to:
1.  Obtain higher fidelity images which more clearly and accurately represent the subsurface geology; and
2.  Derive more intuitive volume-based interpretations showing the 3D distribution of key rock units.
