Product overview

The INTERSECT high-resolution reservoir simulator sets a new standard in 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. Users can run the INTERSECT simulator from Petrel Reservoir Engineering.

Release highlights

The release of INTERSECT 2022.2 delivers many key features in performance, physics, CO2 storage capabilities, field management, usability, and more. These features include performance improvements in GPU, transmissibility effects in the new water-weakening rock compaction model, performance, and robustness of the component solubility in water framework for CO2 storage applications, a template for rig logic field management operations, and ability to export results in comma separated variable (CSV).

INTERSECT 2022.2 key developments

Performance

• GPU simulations that include well drawdown limits should have increased performance compared with previous versions, as this calculation, which previously took place on CPU, now does so in GPU.
  
  
• Substantial performance improvements have been made to GPU and hybrid parallel runs of unstructured grids, where pillar adjacency calculations are required.

Physics and CO2 Storage

• The new water-weakening rock compaction model has been extended to account for transmissibility modifications. With special considerations for chalk reservoirs, it introduces cell-to-cell and well-to-cell transmissibility dependencies on rock stress and water saturation, as well as options for how to consider pressure reversal effects. A model for the rebound behavior of the pore volume is also added to account for physics such as pore collapse, and chalk structure changes with invading water. (Note: this new utility is available at controlled commercial status. Please contact Schlumberger support if assistance is required)
  
  
• The performance and robustness of the component solubility in water (CSIW) framework has been greatly improved in both isothermal and thermal implementations. This comes as part of a continuous effort to support the modelling of CO2 storage and new energy applications.

Fidelity

• The workflow to allow saving transmissibility values and later restoring them at a different point time in simulation has been extended to support restarts. Users can run a restart case and roll back the transmissibility values of a chosen region to the values saved in the base run.

Field Management

• Through a new Field Management template node RigLogicTemplate, users can define in simple syntax complex rig-based operations inclusive of drilling, closing, and performing workovers at both well and completion levels.
  
  
• A new utility called ixf2csv is available, allowing conversion of ixf input format to a CSV representation for later use with the CSV controller. It takes a simulation deck (.afi) as input and extracts the supported fields into a set of CSV files in a dedicated subdirectory. The CSV format can provide greater usability in certain use cases, such as operations with frequent changes to well constraints. 
  
  

Usability

• Summary results can now be reported in CSV file format. The OutputCSV field allows flexible output of single or multiple (per entity type) files. These can be easily consumed into post processing workflows for plotting and analysis.
  
  
• A new command that allows querying cell-based property values for usage in Python scripts is made available in this release, greatly expanding the custom capabilities of the simulator.
  
  
• Summary reports for voidage replacement ratio in both standard and cumulative forms are now available. They can be requested for both field and group level.
  
  
• The Migrator now supports conversion of the 3D reporting for connection transmissibility (CONFAC) and integrated permeability Kh (CONKH).

Users

The INTERSECT simulator brings value to reservoir engineers who perform numerical simulation using high-resolution models and complex field operating conditions. The INTERSECT simulator also brings 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 simulator.
