New Software Release

Product overview

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 40 years due 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.

Release highlights

The ECLIPSE 2022.3 release includes key developments that extend modeling capabilities for autonomous inflow control devices and enhance the performance, usability, and functionalities of the simulator suite

Release updates

WSEGAICD density exponent

For both ECLIPSE 100 and ECLIPSE 300, the pressure drop equation for autonomous inflow control devices (AICDs) has been enhanced to allow an exponent to be used for the density function.

Cumulative output for gas lift

Cumulative totals for field, groups, and wells are now available for the gas lift option in both ECLIPSE 100 and ECLIPSE 300.

For both ECLIPSE 100 and ECLIPSE 300 simulators:

• It is now possible to specify different UDAs for different phases in group keywords which can be specified multiple times for different phases.
• Additionally, the limitation that the field had to be the last group specified for it to have a UDA has been lifted.
• Input file processing error reporting has been improved for cases when the problematic input line is very long or contains tab characters.
• The ECLIPSE simulator Technical Description referencing convention has been improved and updated and is now consistent with the convention used in the INTERSECT high-resolution reservoir simulator.

Additionally, for ECLIPSE 100 simulator

• Several internal algorithms have been improved to reduce memory and other system requirements.
• Checks on the requested maximum number of summary data items have been improved to avoid cases when there was no warning that the value was too small.
• PRT file reporting for the coalbed methane option has been improved to correct issues seen in parallel runs.
• License checking has been improved in parallel to ensure that missing licenses during simulation always generate appropriate messages.
  

For ECLIPSE 300 simulator

• Field and fluid-in-place separators can now be assigned as well separators.
• The workflow for thermal decks with LGRs has been improved to ensure that output suitable for visualization is always generated.
• The behavior when specifying the guide rate in the GRUPTARG keyword now matches the equivalent input when the GCONPROD keyword is used.
• The output of LGR heater summary vectors has been improved.
• A debug facility has been added for convergence failure in the black oil single phase flash.
