    The nearest Geophysics Seminar in Toronto

    Posted by on Friday, 26 February, 2010

    “Improved methods for interpreting magnetic gradient tensor data” David Clark, CSIRO Materials Science and Engineering (Australia).

    17-Mar-2010  from 16:00 to 17:00 , Department of Physics of U of T.

    Recent technological advances suggest that we are on the threshold of a new era in applied magnetic surverys, where acquisition of magnetic gradient tensor data will become routine. In the meantime, modern ultrahigh resolution conventional magnetic data can be use to calculate gradient tenor elements from TMI or TMI gradient surveys. Until the present, not a great deal of attention has been paid to processing and interpretation of gradient tensor data. New methods for inverting gradient tensor surveys to obtain source parameters have been developed for a number of elementary, but useful, models. these include point pole, line of poles, point dipole (sphere), line of dipoles ( horizontal cylinder), thin and think dipping sheets and sloping step models. A key simplification is the use of eigenvalues and associated eigenvectors of the tensor.

    New CSEG’s Technical Luncheons with Carmen Dumitrescu

    Posted by on Thursday, 4 February, 2010

    “Characterization of a Heavy Oil Reservoir using Vp/Vs Ratios and Neural Network Analysis”, Calgary, February 10, 2010

    For heavy oil projects, density and Vp/Vs ratio are very good lithology and fluid discriminators. For this talk I have two objectives: the first one is to predict a Vp/Vs ratio volume based on neural network analysis and the second one is to integrate the Vp/Vs ratio with density and edge detector attributes in an attempt to better differentiate between sand and shale within the oil sand reservoir.

    Neural network estimation of reservoir properties has proven effective in significantly improving accuracy and vertical resolution in the interpretation of the reservoir. The strength of a neural network analysis is the ability to determine a nonlinear relationship between logs and several seismic attributes.


    Recent developments in airborne geophysics at CMOS-CGU Ottawa 2010

    Posted by on Tuesday, 2 February, 2010

    44th Annual CMOS Congress 36th Annual Scientific Meeting of CGU 3rd Joint CMOS-CGU Congress May 31June 4, 2010

    Airborne geophysics is a rapidly-evolving, innovative and competitive field that responds to market demands for added value. This is particularly true in the current economic climate.
    This session features recent developments in platforms, sensors and analysis methods for airborne gravity, magnetics, electromagnetics, radiometrics and laser imaging. Of particular interest are new platforms, for example, low-altitude heliported systems and unmanned air vehicles that have the potential of revolutionizing exploration in rough topography. Another area of growing interest is the fusion of data captured by different geophysical sensors, leading to enhanced visual products and maps. Airborne Lidar, for example, has become a valuable technology that allows building digital elevation models that can be combined with classical potential field data. This integrated approach contributes to more accurate target detection and delineation. With the increased data volume, new analysis strategies are being designed to deliver results quickly and efficiently, in many cases, in real- or near real-time.

    The session welcomes contributions focusing on technology advances and case histories for applications ranging from natural resource exploration to mapping unchartered terrains. In line with the conference’s general theme, contributions related to environmental monitoring are particularly encouraged. The session also aims at bringing together geophysicists and engineers engaged in research and development in airborne geophysics, and working in academia, the public section and private industry.

    GEOCANADA 2010 in terms of geophysics

    Posted by on Tuesday, 19 January, 2010

    In May 2010 the CSPG, CSEG and CWLS will join with GAC, MAC, IAH-CNC, CCPG and CFES to bring GeoCanada, a once-in-a-decade event, to Calgary. This valuable earth science Convention will boast an expanded technical program, extended Exhibit Floor and plenty of networking opportunities for the more than 4,500 expected attendees.

    Geophysics related Sessions:

    Advances in Seismic Acquisition

    This session may include any topic to do with onshore seismic acquisition (offshore is a separate session) including, but not limited to; land access, environmental aspects, line clearance and reclamation, geomatics, community relations, sources, receivers and case histories.

    Seismic Interpretation and Case Studies

    Innovative Groundwater Exploration and Discovery Methods

    Groundwater exploration and discovery methods have seen many advances in the past decade, particularly in the application of downhole, airborne, and space-based remote sensing methods as well as computer modelling and scientific visualization. But sound geological mapping, rigorous field observations and aquifer testing are still required to turn conceptual ideas into wells. This session invites papers highlighting innovative geological, geochemical and geophysical methods to explore for groundwater or to map aquifers.

    Geophysical Exploration 1: Gravity, Magnetics, MTEM, Remote Sensing

    Potential Fields, EM, MT, Remote Sensing Papers are invited which describe the application of gravity, magnetics, electro-magnetics, magneto-tellurics and remote sensing to mining and petroleum exploration and exploitation. The topics will be broken down into land, marine, airborne and satellite techniques.

    Geophysical Exploration 2: Lidar, Sonar, Hi-Res Seismic

    Signal Processing and Algorithms

    Signal processing is at the very heart of seismic analysis. This session welcomes theoretical submissions discussing new or existing algorithms, but also presentations featuring applications of these algorithms in the seismic process. It is hoped that the final programme will feature a combination of the theoretical and the practical.

    Subsurface Imaging and Structure

    How do we unlock the secrets of the Earth? Knowledge of the Earth’s structure, whether the near subsurface or the core, is essential to geoscientists. This “subsurface imaging and structure” session will present the latest techniques employed to further our knowledge of the structure and geological history of our planet.

    The nearest CSEG Technical Luncheon is about signal processing

    Posted by on Sunday, 10 January, 2010

    January 11, 2010 – 11:30am in Calgary Mauricio Sacchi is going to speak about “The Old and New in Noise Removal, Wavefield Representation and Data Regularization”. Mauricio teaches geophysical signal processing, introduction to seismic imaging, and inverse problems at University of Alberta. His research interests are in applied seismology, global seismology and ultrasound medical imaging.

    Traditional noise removal methods based on Fourier analysis, Radon transforms, and prediction filtering have occupied an important place in our arsenal of methods for noise attenuation. They all rely on different assumptions and, in general, on a simple signal model. An open problem in seismic data processing is the establishment of proper basis functions to represent seismic data. In addition, it is important to understand how one can use an optimal data representation to separate signal from random and coherent noise. For instance theories arising from the field computational neurosciences (sparse coding) have proposed algorithms to learn (extract) basis functions from the data. The latter can be used to construct a signal and noise model from the data themselves and therefore, to obtain optimal templates to represent seismic data. I will review how the old meets the new and in particular, how one can complement well-known methods for noise attenuation with novel ideas in the field of sparse coding and compressive sensing. In addition, I will provide examples of seismic data regularization where some of these ideas lead to algorithms amenable of regularizing data in the presence of strong coherent noise.
