TEM software
TEManalyze
Optimize your TEM survey before you reach the field.
TEManalyze is our free software that allows you to identify the most suitable system and configuration, whether sTEM, tTEM, or TEM2Go, while also determining the optimal stacking time based on system capabilities and survey conditions. By predicting achievable resolution and depth of investigation from an expected geological model, the software help you to assess survey performance before going to the field. With only a basic understanding of layer resistivities and thicknesses, TEManalyze can provide actionable insights that save you both time and resources on-site.

TEManalyze features and benefits
Plan, model, and evaluate with confidence. TEManalyze gives you everything you need to optimize your TEM survey before stepping out into the field.
Geological modeling at your fingertips
TEManalyze makes it easy to define an expected subsurface structure by entering layer resistivities and thicknesses. This simple model serves as the foundation for evaluating system performance, guiding you toward realistic expectations for resolution and depth of investigation. By adjusting layer properties, you can quickly explore how different geological scenarios influence measurement quality and system selection.
Advanced modeling made accessible
TEManalyze uses a robust nonlinear inversion algorithm to simulate how the chosen system will image the subsurface. Select between smooth (L2-norm) and blocky (L1-norm) inversion types, each suited for different geological conditions. The software computes forward responses, fits the model to noise-limited data, and provides clear indicators of achievable resolution.
Key Features:
-
Smooth (L2) or blocky (L1) model inversion
-
1D multilayer model with vertical constraints
-
Automatic misfit calculation with warnings for poor fits
-
Forward modeling powered by the Lupus TEM code
Choose the right TEM system for the job
With built-in support for sTEM, tTEM, and TEM2Go instruments, TEManalyze evaluates system configuration, coil geometry, waveform characteristics, and filtering parameters. Users can compare how each system responds to the same geological model, making it easy to select the optimal configuration before any fieldwork begins.
Understand data quality before you measure
Noise level and stacking time directly influence uncertainty and DOI. TEManalyze simulates effective noise levels based on system characteristics and stacking duration, calculates data error bars, and automatically excludes unreliable data. The Depth of Investigation is then derived using the inversion results and noise-based uncertainties, giving you an accurate preview of how deeply and reliably the chosen system can resolve the subsurface.
Highlights:
-
Adjustable noise levels (Low, Normal, High)
-
Customizable stacking times (¼×, Normal, 4×)
-
Effective noise scaling using t−0.5t^{-0.5}
Your questions answered
What is TEManalyze used for?
TEManalyze is designed to help you choose the optimal TEMcompany system, configuration, and stacking time before performing field measurements. By modeling expected geological conditions, it predicts achievable resolution and depth of investigation (DOI).
Do I need detailed geological knowledge to use TEManalyze?
No. Users only need a basic estimate of expected layer resistivities and layer thicknesses. TEManalyze handles the forward modeling, noise simulation, and inversion internally.
How does TEManalyze calculate DOI?
The software computes DOI using the inversion results, noise level, data uncertainties, and system properties. It relies on the established DOI methodology implemented in the Lupus TEM inversion code.
What is the difference between Smooth and Blocky inversion?
A Smooth (L2-norm) inversion is ideal for gradual subsurface transitions, while a Blocky (L1-norm) inversion highlights sharper boundaries. TEManalyze allows you to choose the model type that best matches their expectations.

Why use the TEM geophysical method?
Our TEM technology
The Transient Electromagnetic (TEM) geophysical survey method is a modern technique designed to measure vertical resistivity profiles with particular sensitivity to conductive materials.
- Particularly sensitive to conductive materials
- Non-invasive method using wire loops to transmit and receive signals
- Leaves no trace on the survey site after data collection
- Highly efficient, requiring a transmitter loop and one or two smaller receiver coils
- Can achieve depth measurements of up to 600 meters
- Entire process takes only a few minutes, from setup to resistivity modeling
Where to use TEM
TEM surveys are highly versatile and are particularly effective in the following areas. Our instruments deliver accurate, fast data to solve many geophysical challenges.
Groundwater Exploration: Identifies freshwater reserves, saline water, and contamination zones to optimize well placement and drilling depth.
Mineral Detection: Locates mineral deposits based on their unique resistivity signatures.
Geological Mapping: Reveals the subsurface structure for various geological studies.
Environmental Surveys: Assesses contaminants and salination in the soil.
The benefits of TEM
Transient Electromagnetic (TEM) mapping is a non-invasive method that ensures that survey areas remain undisturbed, as it uses wire loops to transmit and receive electromagnetic signals without leaving physical marks on the terrain.
TEMcompany geoscanners enable fast, accurate geophysical data collection alongside easy instrument setup, delivering significant time savings for consultants, contractors, and clients.
