AR2Tech products

Geostatistics is the most powerful mathematical tool for analyzing risk and uncertainty in spatial data. We bring this technology into decision-making workflows.

A platform designed to accelerate implementations of new geostatistical technologies
We provide proprietary geostatistical libraries that can be integrated into third-party interfaces or be visible with our graphical environment.
AR2GEMS for kriging and simulations

AR2GEMS used for simple, ordinary kriging and sequential simulations.

AR2GEMS for kriging and simulations

Convenient statistical analysis tools, from simple to histograms to advanced clustering and comparison techniques.

AR2GEMS: a modern geostatistical platform

Much more than a geostatistical library, AR2GEMS offers a state-of-the-art version of all foundational geostatistical algorithms, along with a user interface to test the power of these algorithms. AR2GEMS is our proprietary version of SGeMS where we actively develop the next generation of geostatistical algorithms.


  • Loads and works on Cartesian grids, corner-point grids, unstructured grids
  • Loads well data in LAS format, or plain csv files
  • Exports properties in Eclipse or GSLIB compatible formats
  • Wide access to internal data structures with Python


  • Written in C++ for Windows, Unix, Mac OSX
  • Maximum computational performance
  • Thread-safe (parallel) computing capabilities
  • Designed to be a platform for future functionalities

Numerical engine

  • High-end computational libraries (Eigen & Boost)
  • Visualization with VTK libraries
  • Generic code: computation is independent of supporting grid structures (same code for point sets, surfaces, Cartesian grids, stratigraphic grids, unstructured grids)


  • Most GUI commands are scriptable
  • Python capabilities to access AR2GEMS objects
  • AR2GEMS extended with external Python libraries

Advanced customization

Our clients need algorithms that off-the-shelf packages do not provide. We create specialized algorithms that can either be integrated into third-party solutions or used within our AR2GEMS front-end platform. We develop and implement powerful spatial data analysis packages tailored to custom specifications.

  • Advanced plug-ins built on top of AR2GEMS algorithms
  • Specialized algorithms for modeling workflows
  • Integration at various levels (API, scripts, or loose coupling)
  • Training and support

Looking ahead: new applications and opportunities

  • Uncertainty quantification in geomodeling
  • Impact of spatial data uncertainty on decision making
  • Machine-learning for data analysis and predictions
  • Multidimensional analysis, distance-based analysis
  • Downscaling
  • Object-based simulation
  • Connections to other applications (mining schedule, reservoir simulation)

We are always looking for new challenges. We look forward to working with you on your specific projects.
