Time Domain Inversion

PetRos EiKon — Tue, 27 Jan 2009 20:28:54 -0000

While EMIGMA has contained one-dimensional inversion for TEM for a few years now, we have recently released a significantly enhanced version.

EMIGMA has offered a range of capabilities for tdem inversion including:

In-loop and out-of-loop configurations
Transmitter and receiver on different elevations
Vertical and horizontal receiver orientations
Occam overparametrized and Marquardt underparametrized models
Full parameter constraints including selection of parameters for inversion
Multi-layer starting models
Rapid approximate (theoretical) current waveforms and true system waveforms
Incorporation of system filters
Storage of synthetic data from each location
User control of time windows for inversion

However, we have expanded the functionality to now allow more flexibility for production including:

Recovery of inversion settings from a log file
Recovery of inversion processing from either a user initiated stop or a crash. Inversions processed prior to a user initiated stop are saved as synthetic model data so the user may later start up the inversion from the last processed position. Inversions and synthetic data are saved automatically every 100 locations so if there is a crash, you may start from the previous automatic save.
The use of multiple starting models in any inversion processing procedure
The use of the prior data point inverse model as the starting model for the next data point giving the user a style of lateral constraint
Export of inversion models to formats suitable for import to 3D visualization applications and other mapping software

On the Horizon

Shortly we will be releasing a new version allowing the use of multiple datapoints and/or multiple components. This capability is based on several obvious reasons but also on the results of many inversions calibrated to known structure. Among these are:

Multi-component inversion for the same data location provides increased signal to noise aspects in the inversions but also allows more detailed resolution in the underparametrized model.
In-loop data provides more accurate shallow resolution than out-of-loop data while the reverse is true for deeper structure. Thus combining in-loop and out-of-loop data provides significant overall shallow and deep structural resolution.
If the earth is approximately 1D then a combined inversion of multiple data points provides the overall best structural definition. This is particularly useful when needing to do 3D modeling in a non-resistive environment where the determination first of the overall background resistivity versus depth is required.

For release in early 2009.

Magnetic Compensation Plug-In

PetRos EiKon — Fri, 16 Jan 2009 22:47:29 -0000

We now offer a plug-in for Geosoft Oasis to perform magnetic compensation on aeromagnetic data contained within your .gdb files. The compensation coefficients are still computed within EMIGMA from box data but now you may perform the compensation directly through a .GX plug-in to Oasis. The data is recovered automatically from the .gdb file and the compensated channels stored in the .gdb file. The compensation can still be performed in QCTool or EMIGMA. QCTool offers the ability to perform compensation in the field with a low cost product without requiring expensive licenses to be allocated to the field. For a review of our extensive compensation capabilities please refer to the papers #15, 16 and 17 in the technical papers section of our website.

EMIGMA V8.1 is now available

PetRos EiKon — Mon, 28 Apr 2008 20:29:13 -0000

We are happy to announce the immediate release of EMIGMA V8.1, which brings with it complete compatibility with Windows Vista as well as a number of new capabilities and improvements. Current owners of EMIGMA licenses may download this latest version from the Downloads area of our website. Instructions will be provided for you there on how to install our exciting new release.

New features:

Full Vista compatibility: Many hours have been spent to ensure that this version is fully compatible with Windows Vista and EMIGMA’s compatibility extends to Vista’s 64 bit edition. While EMIGMA, being a 32 bit based software package, will not utilize the full capability of the 64bit chipset and CPU, its design will enable some utilization of the 64bit capability. Many applications in EMIGMA run on their own thread and thus it is possible to make good use of a multiple core chip if you have such hardware installed.
Online updates: EMIGMA’s update capability, which allows you to download and install updates for the software has been improved. Clients in certain geographic areas, such as China, who have been unable to use this capability before can now take advantage of this feature.
Contouring: The 3D visualizing contour tool has been completely redesigned to be much more robust and effective. Contours can now be integrated with a 3D surface and the interface has been simplified for ease of use. This tool allows for 3D volume rendering of your magnetic, gravity and EM inversions.
FEM 1D Inversion: The inversion algorithm has been altered to recognize additional relevant factors such as displacement currents resulting in a more accurate inversion. A new constrained Marquardt style inversion has been added to allow you to use a starting model and parameter constraints. These upgrades for high frequency effects have been added to the apparent resistivity and apparent depth calculations.
TEM 1D Inversion: Joint inversion of a customizable combination of components and separations for both Occam and Marquardt inversion types has been added. Incorporating more varied data into the process will provide better signal-to-noise ratios within the inversion. Being able to carefully select data that contain information about different geological structures may enhance the resolution of the inverted models and result in more meaningful models.
Upgrades have also been added for the inloop approximate forward OCCAM inversion.
The TEM Inversion is a full, correct forward modeled based inversion utilizing full parameterization constraints. It also utilizes a type of locally constrained inversion and is developed for production. Thus, inversions are stored after every 500 points and can be stopped and resumed at any time. Multiple starting models and constraints may also be defined for any inversion run.
MT/CSAMT/VLFR Import: EMIGMA has been upgraded for import of table formats for MT and there is an entirely new import added which allows for you to import MT/CSAMT and VLFR data into EMIGMA from QCTool. Organization of ASCII files in QCTool is simple and thus any ASCII file can be reorganized in QCTool for import of these data.
Airborne TEM imports: Airborne TEM imports have been entirely re-done with a new easier and more intuitive interface. For those of you working with large datasets, we have added the ability to import from QCTool.
QCTool imports: We are moving more and more towards importing from QCTool. With its low price (and 30-day free use), it is possible to have your contractor deliver your data, import into QCTool to reorganize, edit and process, followed by interpretation in EMIGMA. Also, it is easy to transfer from a .gdb file into QCTool and vice-versa. Remember that you can process and reduce all of your magnetic, gravity and EM data in QCTool and if you are using the the IP12 series or lower of IP instruments, you can use QCTool for initial processing prior to import into EMIGMA.
FASTTEM: EMIGMA has been upgraded to allow import and use of the FASTTEM system. TerraTEM data may be imported through the AMIRA format but a native TerraTEM import is coming in the next few weeks.
MTEM: MTEM capability has been added. However, licensing is controlled by the company who paid for this development, so you will have to contact us if you are interested.
Bug fixes and minor enhancements: Moving to 8.1 allowed us the opportunity to redesign some overall enhancement to functionality. In the interim, while enabling Vista compatibility, we were able to clean up a number of bugs and irregularities. Several new enhancements have been made. For example, you may pin the main page for ease of use when operating dual monitors and there is very nice right mouse click toggle from profile to decay in the plotter.

EMIGMA V7.8 - New Features

PetRos EiKon — Mon, 20 Aug 2007 21:37:09 -0000

Note: This article is updated in this PDF file.

It has been five years since PetRos EiKon first released Version 7.5 of its interpretation software package. The product is being received internationally with increasing popularity for its integration of software tools for non-seismic geophysical data. Initially released as EMIGMA V7.7 in May of 2004 and now (May/2006) in its third major release, EMIGMA V7.8, has an impressive array of new functions as well as improvements to almost all the older capabilities. In addition, many new features are in development to be released as upgrades later in 2006.

The new version continues to strengthen EMIGMA's historical focus of data simulation from 3D models:

our first 3D gravity modeling algorithms
3D gravity inversion algorithms
gravity and magnetics gradient modelling
increased capabilities for magnetics including the ability to use gradients either measure or processed in the inversion tools modelling
a new more accurate and faster 3D resistivity modelling algorithm

data stacking to allow data analyses for data repeats

New release of QCTool (August, 2007)

PetRos EiKon — Mon, 20 Aug 2007 21:36:06 -0000

The new release (August, 2007) offers further functionalities enhancing QCTool's capabilities and facility. The standard version now includes all gravity corrections, trend removals, IGRF corrections, Lambert projections as well as increased facility with spreadsheet functionalities. The plotter has been enhanced to provided more flexibility and ease when viewing large amounts of data. The survey mode edit and display capabilities have been enhanced and in general there has been a re-working to make the product easier to use, more stable and more functional.

In January, 2006, the new release offered further spreadsheet functionalities facilitating work within large data sets. You can now specify the font of the spreadsheet and easily perform various manipulations with data, such as Copy and Paste or adding different files to each other. The latter feature is especially useful when your data have been collected at different times and you want to put them all together. Also added are two new channels providing time and date information for each row of data.

Included in the Fall/2005 release are point by point IGRF calculations for magnetics using the latest coefficients. Now in QCTool you may perform your "diurnal" and IGRF and drift corrections. Extensions have also been made to the "Append and Merge files" functions.

Please contact Sales if you are interested in discussing these services.

Aeromagnetic Compensaton now available in QCTool

PetRos EiKon — Wed, 31 May 2006 15:24:10 -0000

Petros Eikon has offered aeromagnetic compensation for several years in EMIGMA.

While our capabilities to calculate exception coefficients for the compensation were well accepted in EMIGMA, many users felt that the actual processing of the survey data was too awkward, slow and difficult to integrate back to other databasing software. Since, QCTool has proven to be exceptional in its ease of use, extent of its functionality and ease of migrating to other databasing software, we have added the survey data correction function to QCTool.

The calculation of the coefficients still lies in EMIGMA with its varied tools both for cleaning and visualizing but the coefficients are easily exported for use in QCTool. This also offers the benefit that the EMIGMA dongle need not be carried to the survey area as the coefficients can be calculated at your home office and sent via the internet to the field.
