WinGLink Geophysical Interpretation Software

Process, interpret, and integrate geophysical measurements into a single earth model

WinGLink implements the multimeasurement geophysical workflow beginning with data acquisition through to modeling and interpretation. Recognized as a global standard for processing and modeling magnetotelluric (MT) data, WinGLink includes modules for time domain electromagnetics (TDEM), controlled-source electromagnetics (CSEM), DC resistivity, gravity, and magnetic data. It also provides the capability to post information from vertical or deviated wells on maps and cross sections as an additional model constraint.

WinGLink uses a common graphic interface for database creation, project generation, coordinate conversion, import and export of both data and model, and launch of modules. Each module includes dedicated features for each geophysical data type.


Create and display contoured and color-filled maps with Maps to represent the value types associated with a broad range of geophysical survey data including MT, CSEM, TDEM, gravity, magnetics, and wells. The program can be used to extract and grid both observed and modeled parameters.

Maps provides numerous functions for controlling map gridding and display, for printing, and for constructing the profiles used in many other WinGLink modules. It enables the simultaneous display of stations from different surveys as well as the construction of integrated maps.


Display, edit, and model individual MT, CSEM, TDEM, and DC stations with the Soundings module. The base functionality enables users to display, edit, and perform 1D modeling on each of these data types, though the actual functions differ for each.


Create and display MT and CSEM attribute pseudosections for observed, simulated, and normalized data. Station data can be manipulated in the interactive dialog window, providing the ability to edit each mode, perform static shifts, and enable ordisable station status for all soundings along a profile. Edits made here are propagated into all other WinGLink modules.


Integrate well information with 1D-, 2D-, or 3D-modeled resistivity distributions to generate section views. Section generation can be fine-tuned through the adjustment of several gridding parameters and can be further enhanced by displaying station names and symbols including well tracks, stratigraphy, and other layered data.

2D Modeling

Run interactive 2D modeling for MT, gravity, and magnetic domains. The module is used to perform smooth and sharp-boundary inversions of MT data, including standard MT as well as controlled-source, audio range, and marine MT. Inversion is performed using exact finite difference routines. The 2D - Module provides a comfortable interface for creating and editing 2D meshes and provides the user detailed control over the inversion parameters.

To assist in the interpretation of the modeled data, the module includes

  • options for outputting sensitivity maps
  • creating pseudosections
  • comparing observed and computed responses.

3D Modeling

Build a 3D resistivity distribution model and run 3D forward modeling. It is supported by a powerful graphical interface to import or edit a 3D mesh and transform the results into EDI impedances (MT) or amplitude and phase (frequency-domain CSEM). Forward computation times are approximately one hour on a conventional PC for a 100×100×100 element mesh using six frequencies for the MT case or for 12 transmitter positions (marine CSEM). The forward responses for individual MT mesh columns can be exported as EDI files and then reimported into WinGLink, where they can be assigned to profiles and used in subsequent 2D inversions.

Interpreted Views

Efficiently present data, models, and interpretations in a unique and complete report. The Interpreted Views and Montage module provides the functionality to turn data visualizations into documents. Each document can contain any of the data views created in a specific WinGLink module. For example, a map document can contain any maps or station data generated in the Maps module. Cultural data, interpretational areas, and annotation can also be added to each document. Once created, documents can be integrated into plates where additional legends and annotation can be added.


Obtain support for field acquisition of MT, TDEM, and gravity data. Several sets of utility programs extend the functionality of the core WinGLink modules. Each tool is used for data processing, data display, and file conversion. Available tools include

  • MT: time series editor and processing, cross-power editor, and EDI data analysis
  • Gravity: gravity reduction and tidal correction
  • TDEM: raw TDEM curves merging
  • CSEM: time series editor.
