Isatis.neo · Geostatistics Software for Mining, Energy & Environment

Isatis.neo manages spatial uncertainty through two complementary approaches. The first is kriging variance, which accompanies every estimate with a local confidence indicator, quantifying how reliable the estimated value is at each unsampled location. The second is stochastic simulation, which generates a set of equally probable realizations of the studied phenomenon. From these realizations, Isatis.neo computes probabilities, exceedance thresholds, and risk quantifications, enabling decisions that account for the full range of possible outcomes rather than a single deterministic model.

Isatis.neo covers the full range of geostatistical methods. For estimation: ordinary, simple, universal kriging, cokriging, kriging with external drift, and non-linear methods including uniform conditioning and conditional expectation. For simulation: Sequential Gaussian Simulations (SGS), Turning Bands (TBS), Plurigaussian Simulations (PGS), Multiple-Point Statistics (MPS), and SPDE-based simulations. All simulation outputs feed directly into post- processing tools for risk quantification and probabilistic decision-making.

Yes. Isatis.neo is used by resource geologists and competent persons worldwide to produce mineral resource estimates that meet the requirements of major international reporting standards, including JORC, NI 43-101, and CIM. The software provides fully justified and traceable estimation parameters, complete audit trails, and reproducible workflows, all of which are required for compliant resource reporting.

The Isatis.neo Petroleum Edition is a specialised version designed for reservoir geologists and geophysicists working in oil & gas and geothermal projects. In addition to the full geostatistical toolkit of the Standard Edition, it integrates the Conversions & Uncertainties workflow, a dedicated, preconfigured process for seismic time-to- depth conversion with comprehensive uncertainty analysis. This workflow enables probabilistic gross rock volume estimation, structural uncertainty assessment, and fault positioning uncertainty management — capabilities not available in any other geostatistics software.

Isatis.neo supports an extensive range of formats used across geoscience industries, including CSV/Excel, LAS, Irap Classic, CPS-3, Eclipse GRDECL, SEG-Y, GeoTIFF, ArcGIS, NetCDF, ZMap, Shapefiles, Datamine (dm/dmx), Surpac, Vulcan, Leapfrog (MSH, LFM), and CAD mesh files (DXF, DWG, STL, OBJ, OFF). It connects directly to ODBC databases including acQuire, Microsoft SQL Server, PostgreSQL, and Fusion databases, as well as to Petrel® through a dedicated plugin. Isatis.neo also reads and writes data directly to and from Isatis.py, enabling seamless transitions between the graphical interface and Python-based workflows. For specific compatibility questions, our technical team is available to evaluate your environment.

Yes. Isatis.neo is used by environmental engineers and consultants for contaminated site characterization, nuclear decommissioning, and air and water quality mapping. It produces auditable, reproducible outputs with full parameter traceability — meeting the documentation requirements of regulatory authorities. For contaminated site characterization specifically, Geovariances also offers Kartotrak, a dedicated software solution that covers the full workflow from sampling design to remediation decision- making.

Yes, in two ways. First, Isatis.neo includes a built-in Python calculator that allows users to create custom variables, functions, and post-processing scripts directly within the software — without exporting data to external tools. Second, Isatis.py is a companion library of ready-to- use geostatistical Python scripts that expose the full power of Isatis.neo’s algorithms in your own Python environment. Both solutions use identical algorithms, ensuring consistent results whether you work in the graphical interface or in code.

Isatis.neo is designed for users at all levels. Its guided interface, data-driven parameters, and intuitive workflows make advanced geostatistics accessible to engineers and geologists who are new to the discipline. At the same time, its full range of advanced methods, batch scripting, and Python integration satisfy the most demanding expert users and researchers. Geovariances also offers a complete training catalogue, from introductory courses to advanced specialized sessions, to support teams at every stage of their geostatistical development.

Isatis.neo is available in three editions — Standard, Mining, and Petroleum — each tailored to a specific industry context. If you are unsure which edition fits your needs, or whether Isatis.neo is the right tool for your project, our geostatisticians are available to guide you free of charge within 48 hours. You can also request a guided demonstration on your own data, or access a free trial for up to one month to evaluate the software in your own environment, without commitment.
