May 2015 - EMIGMA developments

We have added a number of exciting features to EMIGMA over the past year. Some of these developments include new imports, better data and error handling, enhancements to the processing of the data as well as many powerful modeling, inversion and mapping features.

Inversions
We are pleased to introduce a number of enhancements to our inversions, especially the Gravity, MT, CSAMT and FEM licenses.

3D Gravity Inversion
Firstly, we have added a constrained Trust region algorithm to replace the earlier slow method. This method not only results in a faster rate of convergence but also utilizes user-defined parameters. In fact, the inversion can now utilize user-specified density parameters and support the import and use of complex polyhedrons as starting models for such things as defining the topography surface or estimates of the basement topology. This is a radical departure from the standard approach of defining a layered-earth model or utilizing a previously-run forward model. Additionally, a number of changes were made to stabilize and speed up the inversion process. The inversion has also been upgraded to allow many more data points and cells in the inversion grid. We expect this inversion will handle your most difficult gravity inversion problem.

Shortly, likely in June, we will utilize a new compilation using the new Intel Fortran compiler which optimizes the inversion of all Intel and AMD processor architectures. This improves the speed to about 3 times of the new May release.

3D MT Inversion
- Improved capability to handle a large number of frequencies and cells and for larger data sets

3D CSAMT Inversion with 3D source
- Faster processing of the data set using a more robust method
- Ability to invert the amplitude of impedance as well as Inphase and Quadrature
- This is in addition to being able to use the measured fields if available.

1D FEM inversion
Supports multiple receiver configurations employed by DUALEM and PROMIS systems

Modeling
We continued to innovate and improve the accuracy of the modeling capabilities of our software over the past year. Some of the most important changes are highlighted below:

EM Simulation
We made some improvements to speed up the simulation procedure as it relates to the joining of the polyhedra (3D objects). The EM simulation procedure in EMIGMA is remarkably different from other applications in that it takes into account not only the interaction between the different structures of a model, but also the interaction between the polyhedra/prisms and the various layers (of the model). In the end, the algorithm computes a very accurate and realistic model based on the given information. Because this aspect of modeling is not handled appropriately in other modeling applications, this makes our software all the more unique and powerful.

We have implanted new capabilities for modeling VLF and VLF-R data. With the dramatic decrease in exploration dollars, many smaller exploration companies are returning to VLF for reconnaissance purposes.

Gravity and Magnetics 3D/2D modeling
Already our Potential fields modeling are both fast and accurate. However, we are presently testing new compilations of the algorithms using the new Intel compiler and this is resulting in improved speeds by up to 10 fold. These upgrades will be available in June.

Mapping
We have added several new features to enhance the mapping capabilities of our software.

Grid Presentation tool
Using Grid Presentation, the user is now able to print any scaled image to a number of large-size map formats, thereby eliminating the need to use highly-specialized and expensive software or printing facilities. The user can customize the map to include a legend, add a logo (or any raster image), create a text box and change the layout of the map prior to printing. Following formatting changes, the user can print the map to PDF by selecting the appropriate paper size including Architecture sizes (Arch A-E) and simply have the map printed professionally. Alternatively, the user can also print directly using any of the supported paper sizes, as needed.

Another unique feature is the ability to manage the Contour attributes. The user is not restricted to pre-defined contour levels, but can instead define the contour interval, draw labels and control the formatting and frequency of the labels—all from within this tool.

Additionally, this tool provides the user with many practical features for handling Transparency/Overlays. For instance, the user can work with up to 5 layers, which include an interpolated ‘Mesh’, Map (Georeferenced map can be loaded), Filled Contour, Contour Line as well as (Survey) Profiles. Using this feature, the user may change the order of the layers and adjust the transparency of each layer. The result can then be exported to a number of formats (raster or raster with Georeferenced formats) and printed, as needed.

Data Import and handling
- Added new FEM import for the GEM-2 system
- Added new FEM import for PROMIS and DualEM
- Improved error handling for MT data (tipper and impedance components)
- Various changes introduced to make the MT/Tipper data import more user-friendly
- Added VLF and VLF-R imports
- Upgrades to CSAMT imports for use with 3D source modelling and inversion to overcome the limitations of the far-field approximations
- New IP imports from QCTool

Processing
- Implemented a new 12th generation IGRF calculation for accurate processing of the magnetic data
- Better handling of DC magnetic derivatives and grid processing features
- Easy conversion of survey data between static and frequency domains as well as frequency and spectral domains
- Ability to select electrode coordinates and specify channels and separations when exporting IP/Resistivity data to XYZ format

GBDecomp
- Updated and improved user interface
- Enhanced support for handling MT data with multiple stations (in a .qct file)
- Enhanced import of decomposed data to EMIGMA for modeling and inversion

Plotting/Display
A number of improvements were made to the overall plotting and display capabilities with some notable exceptions listed below:

IP/Resistivity/MMR
- Ability to plot data as a function of separation
- Accurate calculation of apparent resistivity from a variety of conventional and unconventional survey configurations
- New display options to switch between ‘actual’ and ‘absolute’ data when calculating apparent resistivity
- Several improvements for displaying apparent resistivity using PseudoShow and Grid Presentation

MT/CSAMT
- Added a number of intuitive features for plotting impedance data
- Adept handling of 2D decomposition features for layered-earth models

Misc. improvements
- Better handling of static MMR surveys including Xhole surveys (with both E -dipole and H-dipole receivers)
- Improved forward simulation of DC magnetic and gravity data
- Utilization of gridded data for the Magnetic Vector Inversion (MVI) - Ability to export Euler solutions to .qct file
- Better interface support for the Remanent Magnetization parameter

Polyhedron generation tools
- Ability to generate topography (as a polyhedron file) by combining two .EGR grids (QCTool grids), one for the top of the structure and the other for the bottom.
