New Software Release

The release of Intersect™ reservoir simulator 2025.3 delivers many key features for new energies, physics, usability, and more.

Key release highlights

Model salt precipitation workflows for fast, accurate CO₂ storage simulation

Evaluate the risk of injectivity impairment and well blockage from salt precipitation using the fast CO2STORE method. This is an implementation based on the Eclipse™ reservoir simulator, that enables engineers to evaluate the precipitation of NaCl into Halite with a single command for activation.

New rock mechanics model for cyclic steam stimulation (CSS) processes

Capture the physics of cyclic injection-production processes such as cyclic steam stimulation (CSS) with the introduction of the Beattie-Boberg rock compaction model. This method enables users to set the pressure and compressibility values to precisely control pore volume changes in both reversible and irreversible regimes of compaction and dilation, delivering more realistic simulation of reservoir behaviour.

Cyclic steam stimulation requires special rock compaction physics

Enhanced geothermal modeling with heat flux boundary conditions

A new heat loss model is now available with flexible control of heat boundary conditions. This enables modeling of phenomena such as volcanic intrusions in geothermal workflows.

Key enhancements

Usability

• Ranges of cells can now be defined more efficiently in the CellSelectionFamily node. Users can use a hyphen (-) to easily define multiple sequential cells without specifying each one individually.
   
• Inter-region flows at reservoir conditions for oil, gas, and water phases can now be reported as summary vectors, enabling a better understanding of fluid flow between reservoir regions.
   
• The recently released functionality enabling output of OFM™ well and reservoir analysis software, has been enhanced to support a wider range of reporting vectors for well and completion properties. Additionally, support has been added to the migrator for Eclipse simulator cases that include the OFM software keyword.
   
• The Eclipse simulator keywords for constant pressure analytical aquifer are now migrated from the Eclipse simulator to the Intersect simulator. This enables an easier transition to the Intersect simulator for models with constant pressure and constant pressure gas aquifers.
   
• A workflow example has been added to illustrate modeling of critical mineral (lithium) extraction from a shallow brine aquifer. It demonstrates features such as brine tracking and constant pressure boundary conditions, which are commonly used in this type of modeling study.
   
• The documentation has been revised to highlight support for RESQML as a format for grid geometry and properties. These file formats can be included in a simulation deck as pairs of EPC and HDF5 files and can be used in place of the GSG file format. Petrel subsurface software can natively export simulation cases in RESQML format. This and more detailed information are now reflected in the documentation.
