INTERSECT 2019.1 delivers key features around the four main pillars of Fidelity, Physics, Performance and Field Management. The new release also delivers special functionalities around fidelity and physics.
The INTERSECT simulator supports a wide range of physical models, allowing the user to capture a large scope of reservoirs and enhanced oil recovery methods. INTERSECT 2019 allows users to model surfactant considering the polymer and extra microemulsion phase.
With high fidelity, advanced physics, and increasing complexity in models, performance is vital to improve the speed and quality in decision-making. The INTERSECT simulator is committed to high performance computing (HPC), from both software and hardware aspects, while leveraging new digital and cloud technologies. Speed increases are obtained from multipronged approaches, ranging from hybrid parallel that improves scalability and reduces memory use, continuous improvement in linear and nonlinear solvers, to code modernization and optimization to benefit from the latest hardware technologies. Performance improvement is delivered year-on-year.
During the field development life cycle, there are wide-ranging complexities from planning to operation. Accurate modelling of such complexities and the reliable prediction of future scenarios are critical to supporting big investment decisions while minimizing the risks. With distinctive reservoirs and various development options, customers require tools with flexibility and versatility to solve unique challenges, while following the existing corporate processes.
In this release, we have focused on improving usability, enhancing integration, and providing openness and extensibility, to enable our customers to explore a wider spectrum of possible scenarios than they ever could before.
INTERSECT 2019.1 Key Developments
Depogrid Dual-Porosity: Dual-porosity gridding option in Depogrid is fully supported in the INTERSECT simulator
Dual-porosity and dual-permeability simulation for Depogrid is now supported. This enables the accurate representation of not only the structural and stratigraphic complexity, but also the simulation of naturally fractured reservoirs.
Mature field: Report cumulative water flux as cell properties.
INTERSECT 2019 adds a new family of grid cell properties to report cumulative water flux (CWF) flow through cells. The reporting of these properties opens new opportunities for using CWF quantities in history-matching and in managing mature waterflood fields.
INTERSECT 2019.1 delivers advanced enhanced oil recovery (EOR) developments around polymer and surfactant. Lab to field workflows have been created in Petrel RE to work directly with INTERSECT 2019.1 and provide a seamless user experience
- Surfactant is used in EOR schemes to lower interfacial tension and increase oil recovery. INTERSECT 2019.1 introduces a new surfactant model that considers the extra microemulsion phase and advanced surfactant physics. It enables users to accurately model the surfactant and polymer recovery processes.
- The combination of polymer and low salinity injection in the same simulation model is now possible.
Hybrid parallel, introduced in the previous version, has increased the speed in simulation models around the world.
In INTERSECT 2019.1 hybrid parallel was optimized to improve the suggestion of threads to use in each simulation, as well as other major improvements around solver which increases the overall simulation speed of the INTERSECT simulator.
- Includes automated hybrid parallel as an option, which allows users to request a recommended number of threads for hybrid parallel runs. This option analyzes the simulation case and selects a number of processes and a number of threads that are likely to improve performance.
- The SWIFT pre-conditioner has been improved to accelerate linear convergence. This reduces overall run time, especially in large-scale thermal simulation cases.
In INTERSECT 2019.1 streamlines are generated integrally while simulator is run allowing full understanding of the reservoir connectivity.
- Enables the generation of streamlines at run time when required. Streamline geometry and properties are output for visualization. Injector-producer patterns are established based on streamlines and dynamic pattern properties are available, which include rates and volumes in patterns as well as injection efficiency. Streamline tracing has been implemented to support parallel execution on large models. This facilitates the understanding of reservoir connectivity and fluid flow patterns for large, heterogeneous reservoirs. Workflow support is provided in Petrel 2019.1, where you can define simulation case process to request streamline generation and summary results.
- Simulation Run Time supports the one-click launch of simulation cases where multiple reservoirs are coupled. This release schedules the simulation runs for individual reservoirs and automatically sets up the communication across the reservoirs.
Complementary to the automated local grid refinement (LGR) process in the Petrel platform, INTERSECT 2019.1 allows the definition of LGR on pillar grids in the IXF file directly. Grid in EGRID format containing the LGRs can be exported and visualized in the Petrel platform. Properties such as well connection factors, cell properties and cell-to-cell connections are automatically updated. This facilitates flexible grid management workflows such as global refinement (as AUTOREF in the ECLIPSE simulator).
A new simplified region mapping schema was introduced in INTERSECT 2018.2 with tabular format that offered improved usability while supporting existing functionalities. This simplified region mapping schema is now made default in INTERSECT 2019.1 and Petrel 2019.1.
