April 2014 - New IP/Resistivity Developments

Last year, we completed major upgrades to our MT and CSAMT (with full 3D source) licenses and this year, we have released major upgrades to our Resistivity and IP licenses. We believe that EMIGMA is now the most comprehensive software package for interpreting and processing such data.

Data imports and processing

  • Range of native instrument formats – Zonge, GDD, Scintrex, IRIS
  • Improved generic format imports – (Geosoft compatible)
  • Enhanced data processing in QCTool and then easy import to EMIGMA
  • QCTool is now a very useful tool for editing and processing your field data to clean up errors in the data, check repeats, plot data, etc.

Survey Configurations
EMIGMA supports a wide-range of configurations – Dipole-Dipole, Pole-Dipole, Pole-Pole, Gradient, Schlumberger, Wenner, Surface to Borehole, Borehole-to-Borehole, MMR, MIP

IP Data Presentation
EMIGMA is unique in that you can work with your time domain IP data either primary voltage normalized or simply as current normalized ( i.e. the entire survey is set to a constant voltage through the import and merging process). The former is quite conventional where the latter offers you a very different view of your data. In this case, data is present as on-time data ( your resistivity data) and off-time data with both in the same voltage units. In this way, you can examine your data as you would your TEM data. You will find this capability very useful in understanding your data. You may with a click of the mouse convert your data or your modeled data to the standard convention.

Data Display and Analyses and Correction
QCTool offers a very easy to use, inexpensive and comprehensive software package for basic data displays, analyses and corrections. Extremely light weight as regards system requirements and very convenient both in the field and the office.

EMIGMA provides a range of tools for data imaging including

  • A very comprehensive data plotting tool allowing displays via profile, time window and separation. Multi-component and multi-line plotting, data vs model plotting and many other useful features.
  • A multi-dimensional grid and display allowing to incorporate in one grid, all separations and all time windows or frequencies. High resolution grids and grids with varying grid points depending on centre point changes.
  • 3D surface displays of data
  • 3D pseudo-sections
  • 3D volume displays of inversion grids and models
  • 2D pseudo-sections and resistivity-depth sections

Forward Modeling (ie. Simulation of Model Responses)
EMIGMA offers comprehensive 3D and long-strike 2D for resistivity and time and frequency domain IP. Several algorithms are provided, some for quick approximate solutions and others somewhat longer computations for a complete and fully accurate solution. In the complete solution, no shortcuts or approximations are made. The full effect of the charges, interactions between targets, effects of the current and voltage wires, etc. are accounted for. We have done considerable work for this release to improve all aspects of our solutions. But, there are some new additions
- Surface to Borehole and Borehole to Borehole both for voltage receivers and for magnetic receivers (MMR and MIP). This necessitated some additions to our tomography tools.

3D Resistivity Inversion
EMIGMA has had 3D resistivity inversion of a few years now. But, in the last year, we have had the opportunity to use it ourselves for contract work. As a result of this work, we have made many improvements to the inversion tools and we believe you will find it more than a little interesting to utilize our inversion and compare to other inversion code that you might have. For example, try some accurate forward models and try your other inversion out on the results. You may be surprised.

2D Resistivity Inversion
The 3D resistivity inversion tools are available for 2D inversion for a single line. The software recognized automatically that there is only 1 line and builds an appropriate grid. Note: There is no mathematical foundation for a traditional 2D inversion but there is no reason one cannot have a single constant grid cell along strike. We automatically select an appropriate strike length for these cells but you may modify this length as you wish. In this process, an output inversion section file is produced for viewing in our PEXSHOW tool or exporting to other software.

1D Resistivity Inversion
EMIGMA offers both over-parametrized inversions (so called Occam) and an under -parametrized global search method. These are useful with your data even if not in a 1D environment as they give useful structural information as well as depth of investigation.

3D IP Inversion
We are working on this and hope to have something for you to try later in the year.
