The ECLIPSE industry-reference reservoir simulator offers the industry’s most complete and robust set of numerical solutions for fast and accurate prediction of dynamic behavior for all types of reservoirs and development schemes. The ECLIPSE simulator has been the benchmark for commercial reservoir simulation for more than 25 years thanks to its extensive capabilities, robustness, speed, parallel scalability, and unmatched platform coverage. The ECLIPSE simulator covers the entire spectrum of reservoir modeling, including black oil, compositional, thermal, and streamline simulation.
The ECLIPSE 2020.1 release includes new licensing behavior to improve performances and improved simulator capabilities in field management and fidelity. Block parallel license is extended from 16 to 32 processors. ECLIPSE 2020.1 also delivers various enhancements based on client feedback. Dynamic well list feature is extended to accept a static or other dynamic list as an initial pool of wells to select from. OPERATE and OPERATER keywords are extended to allow conditional definition of properties and regions.
Block parallel license: The block parallel license facility has been extended from 16 processors to allow runs with up to 32 processors, in both ECLIPSE 100 and ECLIPSE 300. This facility can be accessed using the BPARA keyword.
Dynamic well list extension: The dynamic well list features enable the user to group together all the wells from an initial group satisfying a dynamic condition, e.g., having water cut above a certain level. Such lists can be used for reporting or applying some actions. Previously, a static group was used to define the initial pool of wells to be selected from in the dynamic list. This initial group can now be alternatively provided as another well list, either static or dynamic. This new feature is accessible in both ECLIPSE 100 and ECLIPSE 300.
Improved OPERATE and OPERATER functionality: In ECLIPSE 100, the OPERATE and OPERATER keywords enable the user to define and manipulate grid properties based on a predefined syntax. Their capacities have been extended in ECLIPSE 100 to allow conditional definitions of properties and regions: In the REGIONS section, new “IFXXX” operators have been added. REGIONS properties can now be edited based on user-provided conditions, such as Greater Than, Lower Than, and Equal To. For instance, FIPNUM regions can now be assigned based on range of porosity, depth, or permeability.
In both ECLIPSE 100 and ECLIPSE 300, the documentation and checking has been improved to clarify which operations and arguments are permitted in different sections and to avoid situations where runs would continue despite a specified operation not being possible.
ECLIPSE 2020.1 contains several changes to address issues discovered in previous releases, as part of our on-going commitment to improving the ECLIPSE simulator. For instance, for ECLIPSE 100:
Additionally, for ECLIPSE 300:
