New Software Release

INTERSECT 2021.2 Now Available

Friday, 02 July 2021

Product overview

The INTERSECT reservoir simulator sets a new standard for reservoir simulation that goes beyond the capabilities offered by current generation simulators. The result is improved accuracy and efficiency in field development planning and risk mitigation—even for the most complex fields. 
The INTERSECT simulator enables engineers to accurately and quickly model

  • complex geological structures 
  • highly heterogeneous formations 
  • challenging wells and completion configurations 
  • advanced production controls for reservoir coupling and flexible field management.

Petrel Reservoir Engineering constitutes the user environment for all Schlumberger reservoir simulation solutions, and you can run the INTERSECT simulator from Petrel Reservoir Engineering.

Release highlights

The release of INTERSECT 2021.2 delivers many key features in innovation, field management, usability, physics and fidelity. These features include the extension of the machine learning critical temperature calculation in the simulator to user defined external feeds, use of expressions in real data type fields in certain Field Management nodes,  improvements for steam rate and steam trap well control modes for thermal recovery, enhanced support to history matching OBSH workflows, improvements to the construction of coarsened Multiscale grids, among others. The migrator was also improved to support additional separator and surface equations of state related ECLIPSE keywords.

INTERSECT 2021.2 Key developments


  • Machine Learning for external compositional feeds: the previous release introduced a novel method of computing the critical temperature of a given fluid using machine learning, generating training data from internally available injection streams. From this release, you can now supply external compositional feeds to generate training samples using the CriticalTemperatureData node, allowing handling of cases such as enumerated initialization, gas reinjection and compositional gradients.

Field Management

  • Real data type with expression: a numerical expression can be now used in fields that accept the ‘Real’ or ‘Real []’ data types in certain Field Management nodes, allowing great flexibility in the definition of fields of entities such as wells, completions, groups, and others.

  • Defaulting of wellbore fluid models: a new DefaultFluidModel field has been added to the AllWellCalculationOptions node to control how the wellbore fluid model is defined when not specified elsewhere, including options to match ECLIPSE 300 behavior. 


  • Improvements for Steam Rate and Steam Trap well control modes: two additional steam trap well constraints formulations have been added under the SteamTrapFormulation field on the AllWellThermalOptions (or WellThermalOptions) node. These are aggressive formulations when a trap is set on a producer, locking onto the control mode very soon after switchover in a SAGD operation, and keeping steam production very low compared to other trap formulations.


  • Additional well constraint reporting: the list of reported constraints specified by the user, allocation actions and networks has been greatly expanded. A full list can be found in the release notes.

  • Supporting multiple OBSH historical data files in a single HistoricalDataControl node: the DataFileName field has been updated to allow for the specification of multiple historical data (obsh) files, permitting data to be split over multiple files of different data frequencies. 

  • Allow the use of wildcards and multiple names in local FM IX: you can now use wildcards and multiple names in local FM IXF nodes to match multiple node names.

  • Fault names in the NNC report: fault names are now provided in the NNC report file. You can turn off the option, which is enabled by default, using the IncludeFaultNames field in the NNCReport node. 

  • Migrator: the following separator related keyword is now migrated: FIPSEP. Additionally, surface equation of state support has been added to the migration of FIELDSEP, SEPCOND and FIPSEP. More information can be found in the INTERSECT User Guide. 


The INTERSECT simulator sets a new standard for reservoir simulation, bringing benefits to reservoir engineers performing numerical simulation using high-resolution models and complex field operating conditions. The INTERSECT simulator also brings value and benefits for production and completion engineers working with advanced completion simulations and complex hydraulic fracture scenarios. Reservoir geomechanics engineers also can use the INTERSECT simulator when dealing with cases like reservoir integrity analysis and permeability changes, which is possible through the integration of the INTERSECT simulator and VISAGE* finite-element geomechanics simulators.
