New Software Release

The release of Intersect™ reservoir simulator 2025.2 delivers many key features in new energies, physics, performance, and more

Key release highlight

 

Significantly reduce computational costs with new sector modeling workflow

Leverage sector modeling to extract areas of interest from full field simulations and conduct detailed analysis of key reservoir zones. This targeted workflow enables dedicated pilot projects and infill well studies to be performed at a fraction of the computational costs, accelerating decision-making.

 

Sector model regions defined in a full field model

 

Enhanced reservoir characterization using local grid refinement (LGR) support for Depogrid

Enhance reservoir modelling precision in areas where detail is needed using unstructured depogrids. Through the integrated Petrel™ subsurface software workflow, complex features such as near-well regions and fault zones can be efficiently defined and easily simulated.

 

 

Simpler fluid model definition for thermal processes

Thermal fluid definition has been streamlined to require only a single hydrocarbon component with essential properties, significantly enhancing usability. This simplified approach is particularly useful in new energy applications, such as carbon storage in saline aquifers and geothermal resource development.

 

 

Key enhancements

 

Performance

• Gravity drainage is now supported in multiscale sequential fully implicit (SFI). These cases may see significant performance gains with the new solution framework.

Physics and new energies

• The viscosity mixing rule option has been extended to support isothermal compositional simulations, enhancing flexibility and accuracy of fluid modeling in the simulator.
• Increased consistency between the density calculations used in isothermal and thermal models considering component solubility in water (CSIW). This should ease the transition and comparison of modeling approaches, for instance when evaluating the thermal impacts of CO2 storage from an isothermal starting point.

Usability

• A new option has been added to output oilfield manager (OFM) well and reservoir analysis software data directly from the Intersect simulator. The generated files can be imported directly into the software and complement its native analysis features.
• The Migrator has been enhanced to translate well economic control (WECON) Eclipse reservoir simulator keywords directly to Economic Logic Template and Modification Logic Template Intersect simulator nodes. This results in a more compact and expressive ixf language.
• A set of fields has been added to enable specification of upper and lower limits for transmissibility between adjacent cells in horizontal and vertical directions. This feature, in combination with the pre-existing non-neighbor connection (NNC) transmissibility limits, can be used to quickly establish physical limits for transmissibility values, improving overall performance.

Platform availability

• Support for Red Hat Enterprise Linux Server 9 Update 5 (x86_64) has been added.
• SLB licensing, the application that manages licensing for the Intersect and Eclipse simulators, as well as other SLB software, has been upgraded to its 2025.1 version.
