OpenFlow Suite 2024

OpenFlow Suite

OpenFlow Suite 2024 represents a significant achievement in the ongoing evolution of our subsurface software technologies, with a primary focus on addressing the emerging challenges encountered by the upstream energy sector.


Our simulators have undergone substantial enhancements, not only reinforcing our traditional workflows for oil and gas exploration and production but also offering state-of-the-art capabilities for deep geothermal exploration and development, as well as exploration for natural hydrogen, helium, and lithium, and the screening, development, and monitoring of CO2 storage sites.


Numerous new numerical schemes for early diagenesis, fluid injection, and geomechanics have been introduced, accompanied by a plethora of new features, performance optimizations, and improvements in usability, ensuring heightened efficiency during model construction, running, and analysis.


A notable addition in the 2024 version is the introduction of a new method for assisted calibration of models through probabilistic optimization, allowing users to automatically enhance the calibration of their models while avoiding the trap of local minima.


All new functionalities are detailed for each software in the release notes available in our user area, where you will also find the installation binaries.


OpenFlow Suite is also available on the cloud, which allows a global access to a high-performance and always up-to-date installation, tailored to your operational needs.

Stratigraphic Modeling with DionisosFlow

DionisosFlow® 2024 introduces new features and capabilities that build on previous developments and integrate years of research into the industrial version.


Benefiting from last year’s “tracer” editor, this year’s DionisoFlow® includes a “continental tracer” option which simulates subsurface lithology dependant tracer production and transport through the infiltration of rainwater in the vadose and phreatic zone. Subsequently, this new option allows for a calculation of a “diagenetic reactivity index” based on each cell’s history.


To give the user more versatility in the wave modelling module and to better relate the input to the environmental forcing factors, this year’s version allows the user to input the wave height and wave period to define a wave.


And for a better post-processing performance, this DionisosFlow® 2024 offers a better, prettier, and more fit for purpose new section editor.


Through its link to CougarFlow®, this year’s DionisosFlow® benefits from a probabilistic optimization algorithm that enhances its automatic calibration capability.


Finally, and as with every new version, DionisosFlow® 2024 also offers a number of adjustments and additions that will enhance the user experience and provide more versatility.

2D Kinematic Restoration with KronosFlow

The 2024 version of KronosFlow™ aims at enhancing study productivity through new features, tools available during the restoration process and expanding basin modeling simulation capabilities.


Notably the layering workflow has been updated with a new isopach user-defined method. This dedicated method bring more flexibility for the user to quickly add units at the age of deposition once the restoration steps are already done.


Several basin modeling options have been added such as the ability to assess biogenic gas with migration and the possibility to model deep gas sources, unlocking deep CO2 or H2S risk assessment, but also exploration workflows for natural hydrogen or helium. This same functionality has also been thought to evaluate CO2 storage potential in saline aquifers, allowing for preliminary but sound characterization of storage capacity, seal efficiency and aquifers connectivity.


Finally, users can now benefit from CougarFlow’s developments to run risk and sensitivity analysis as well as automatic calibration to well data. These extended functionalities enable a seamless integration with E&P workflows beyond the OpenFlow Suite helping communication for decision makers.

Basin Modeling & Petroleum System Analysis with TemisFlow

TemisFlow® 2024 paves the way for new basin modeling applications focused on alternative energy sources and decarbonization while improving further its exploration workflows for oil and gas.


ArcTem simulator now benefits from the deep gas sources functionality, unlocking deep CO2 or H2S risk assessment, but also exploration workflows for natural hydrogen or helium. This same functionality has also been thought to evaluate CO2 storage potential in saline aquifers, allowing for preliminary characterization of storage capacity, seal efficiency and aquifers connectivity. Thanks to the addition of tracers, it is now also possible to do contamination assessment.


Calculators have been enhanced to handle high-resolution time steps and extremely low-density fluid to answer new energy challenges and improve the gas migration characterization. Many other improvements related to visualization options, trap charge assessment or data management have also been brought forward.


Finally, CougarFlow® 2024 is available in combination with the ArcTem simulator with all the bells and whistles for risk assessment and sensitivity analysis. It also brings a long-awaited functionality to help in the calibration process based on optimization algorithm applied to response surfaces. This new method allows finding the best-calibrated models for a given set of uncertain parameters and provides the most probable range of distribution for those uncertain parameters to calibrate the model, improving our understanding of the model uncertainty.

Fracture Characterization & Modeling with FracaFlow

This new version of FracaFlow® builds on the developments released in the previous version. We kept on improving the same modules as in 2024, which are also among the most used, e.g. the automatic KH calibration and the computation of the fracture network equivalent properties (upscaling).


These awaited developments strengthen FracaFlow®’s main workflow, by proposing new options or improving the existing functionalities.

The main developments are:


  • New functionality to update both conductivity and aperture in the calibration module (AKC).
  • New hybrid solution for upscaling mixing the analytical and flow-based solutions.

Fluid Flow Simulation with PumaFlow

PumaFlow® continues to move towards new energy transition challenges. Combinations of options are more and more demanding to deal with specific needs like Co-production of Heat and Lithium and Dual medium and Thermal computation for geothermal in fractured zone.


Tracers have been extended to be initially present in the reservoir model and produced as co-product of simulation. Tracer tests can be fully represented and matched, allowing for accurate predictions of mass of products in solution like Lithium.


Complexity of thermal effects in fractured rocks can be modeled with property changes either in Porosity or Permeability.


On the other hand, PumaFlow® 2024 Graphical User Interface is still evolving to give more flexibility in QC and results analysis with new functions in the Cross Plot and Section Editor.


Several reported issues have been corrected to feed the non-blocking maintenance.

Uncertainty Analysis with CougarFlow

CougarFlow® continues to enhance and enrich its capabilities to meet the needs of geoscientists for uncertainty quantification, risk management, and optimization.


Two years after introducing the gradient based optimization, a new global approach was developed to avoid local minima and propose more than one calibrated model. The new Probabilistic Optimization is based on the full grasp of the uncertain domain through the response surface. See TemisFlow® and DionisosFlow® release notes for more details.


The uncertain parameter tree has undergone a thorough overhaul to accurately reflect the configuration parameters within TemisFlow® and DionisosFlow®, both by name and organization. Now, each new feature introduced in either of these software packages will be readily accessible in CougarFlow ® for evaluating its impact on the response. Additionally, new parameters are now accessible, particularly for Visco. Expanding on this effort, uncertainties are now also available for ArcTem in both 2D and 3D. See DionisosFlow®, TemisFlow® and KronosFlow™ release notes for more details.


Various other improvements have been brought to the software, notably the possibility to create custom designed result of interest (ROI) from any property accessible under the workflow. Finally, the map analysis feature has been enhanced to improve its usability, facilitate the calibration of the response surface, allow the creation of an estimation map of a specific simulation, generate contours, and manage the locator.
