Magnetotelluric Developments

New Import Facilities

  • .edi format: There is now an import facility for .edi format into QCTool for all data elements and processed elements. QCTool can then be used to quality control and edit your data. Impedance and Tipper data can then be imported to EMIGMA via the import facility for such data using the .qct format.
  • Stratagem data: Native Stratagem files can now be imported to QCTool through the Stratagem import facility. Once you have analysed and appropriately edited your data in QCTool, it can then be imported to EMIGMA from the .qct format.
  • 1D Inversion: We have utilized Occam type inversions to date, but as a process of upgrading our MT tools, we have added a parameter constrained “Marquardt” style inversion. These inversion tools are quite different from the original Marquardt inversion techniques yet similar. It is an under-parametrized inversion approach and uses analytic gradients and numeric curvature terms but the actual minimization approach is much closer to our other documented inversions. (See downloads page).

    Display Capabilities: Some significant work has been done on plotting, gridding and visualization displays for natural field data.

    3D Tipper Inversion: A 3D tipper inversion in available but is not part of the standard license. Please contact sales if you are interested in such algorithms.

    3D Impedance Inversion: We are in the last stages of testing and hope to have something available for September. This will be part of the standard MT license and will be free as an upgrade to all clients having licenses under maintenance.

    CSAMT Developments

    For many years, EMIGMA has contained 3D CSAMT modeling. However, it was quite distinct from standard CSAMT modeling in that the actual geometry of the transmitting wire was used including not only the injected currents but the currents induced in the ground due to the magnetic fields emanating from the wire.

    A few years ago, with UN support, we upgraded our CSAMT tools to import Zonge data including both impedances and the synchronized measured fields (ie. Voltage and Magnetic fields). At this time, we also added constrained 1D inversion using the full source effects. These developments combined to allow the use of data not only in the far field but also in the near field thus allowing the use of all measured frequencies.

    Recently, we have upgraded our CSAMT tools again and are in the middle of more extensive developments. First, we have upgraded the import tools through the .qct format thus essentially allowing any data that can be formatted to a spreadsheet or .xyz format to be imported. Also, as part of new developments to more closely support all Phoenix instruments, we have developed imports to EMIGMA for their .avg format which includes impedances and fields.

    Generally, we upgraded our display and survey design tools for CSAMT so as to move closer to having the combination of EMIGMA and QCTool be a comprehensive tool for survey design, QC/QA, processing and interpretation for CSAMT. This is motivated by what we see as a strong growth in the wish to use such data and by the limitations of being forced to interpret such data as MT data but also due to our involvement as consultants in such projects.

    We have reworked our CSAMT 1D inversions to be more rugged, accurate and fast. 3D CSAMT inversion is in development and likely to be released in the fall of 2012.
