GMG Mesa Expert 17.7

Available versions : 17.5.2 , 16.3.5 , 16.0.2

GMG Software ION’s GMG Software is recognized worldwide for providing the upstream exploration industry with software solutions for acquisition survey design, illumination modeling, acquisition project tracking, and near-surface refraction statics.

GMG software is used by contractors and oil & gas companies to gain greater assurance that the seismic data being acquired will deliver a superior seismic image within their budget constraints. Key offerings include: MESA MESA software for land 2D, 3D, 4D and full-wave (multicomponent) acquisition design, is a tool of choice when planning, modeling and tracking complex acquisition scenarios.

Companies around the globe have used MESA to achieve their imaging objectives. Whether a seismic survey is basic or complex, MESA delivers decision-making functionality that can make any acquisition program a success

There are a few important changes that you should read:

1. There are some database format changes for MESA Version 16.2 projects. Once a project has been saved in Version 16.2 you should not re-open projects in earlier versions of MESA or you will risk corrupting your projects.

2. The colorscales and configuration files are now installed in C:\ProgramData\GreenMountain\colorscales and C:\ProgramData\GreenMountain\config respectively. The first time that MESA 16.2 is launched, the user preferences will be updated to point to the new colorscale and configuration file directories. If you have custom colorscales or configuration files, you can either reset the user preferences to their previous locations or you can copy your custom files to the new directories.

3. The release notes will appear when you start MESA as long as Display Release Notes on Startup is set to Yes in the user preferences. The user preferences are also used to set the default data directory for MESA projects.

Version 16.3.5 Enhancements and Fixes

1. Fixed an issue with the calculation of inverse templates (sources firing into a given receiver). This solved potential problems transferring MESA geometries to Gator.

Version 16.3.4 Enhancements and Fixes

1. Improved the performance of the Bin Attribute Analysis window.

2. Fixed multiple issues with elevations, shot depths, receiver depths, and water depths when exporting marine geometries to SPS.

Version 16.3.3 Enhancements and Fixes

1. Fixed an issue with inverse templates not exporting to Marlin properly.

Version 16.3.2 Enhancements and Fixes

1. Added an option for decimating hydrophone positions in the P1/90 offshore export.

2. When importing xy-coordinate information from external ASCII files, there is now an option to handle situations where the file is missing coordinate data for one or more stations. You now have the option to temporarily assign a coordinate of (0,0) for any missing data in the file instead of simply cancelling the import.

3. Fixed a display issue in Edit Templates mode in which the last source in the project could not be selected to view its template.

4. Fixed a problem reading in P1/90 files from simultaneous shooting geometries.

5. Fixed an issue with the persistence of the number of station number digits when exporting MESA geometries to SimSurvey and Marlin.

6. Fixed a problem with the calculation of hydrophone positions when creating towed steamer geometries by shooting existing marine sail polylines.

7. Fixed an issue in which some source points weren’t getting re-assigned cable configurations when re-shooting existing marine surveys.

8. Added the numbering options dialog box to the marine sail line generation tool.

9. Added an option to the SEGP1 and SPS export dialog boxes for resetting the filename prefix to the name of the currently loaded database.

Version 16.3.1 Enhancements and Fixes

1. Fixed a problem loading pre-version 16 MESA databases as additional projects. There was an inconsistency with the format of the stored datum transformation which prevented additional projects from being loaded simultaneously.

2. Added the run in/out capability for geometries created using marine sail polylines.

3. Rotation/translation functions are now accessible prior to the creation of sources and/or receivers. Previously, a project needed sources or receivers for the translation options to be active.

4. Added support for reading receiver attributes from Gator version 2.0 MFA files.

5. Fixed an issue launching SimSurvey when special characters are included in the path name.

Version 16.3.0 Enhancements and Fixes

1. MESA now includes WMS data from OnTerra-MapSavvy. This service includes Bing Maps and Here Maps data layers.

2. Fixed a screen updating problem when zooming the Design Window with a WMS layer displayed.
