The ECLIPSE industry-reference reservoir simulator offers the 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 35 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 2021.4 release includes key developments that enhance the performance, usability, and functionalities of the simulator suite.
Additional user-defined-argument (UDA) support
UDA support has been added to the following keyword arguments:
Improvements to the CO2STORE option
Improvements to radial grids
Various improvements have been made to the MULTR and MULTTHT functionality and for circle completions.
In the ECLIPSE 100 simulator:
In the ECLIPSE 300 simulator:
New reporting for well connection status
New CSTAT and LCSTAT summary keywords have been added to report the status of well connections in a similar manner to the WSTAT summary keyword for wells.
As part of our ongoing commitment to improving the ECLIPSE simulator, ECLIPSE 2021.4 contains several changes to address issues discovered in previous releases. For instance, in both ECLIPSE 100 and ECLIPSE 300 simulators
