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 robust capabilities, speed, parallel scalability, and unmatched platform coverage. The simulator covers the entire spectrum of reservoir modeling, including black-oil, compositional, thermal, and streamline simulation.

Release highlights

The Eclipse 2023.3 release includes key developments that improve CO2 storage functionality, as well as usability enhancements to various features.

Release updates

Improvements to CO2 storage functionality

Aiming to enhance CO2 storage applications, this release focuses on a quality and enhancement campaign to around CO2STORE workflows. Improvements include:

• Kvw table reporting is now available for isothermal CO2STORE models. CO2 and H2O salinity dependent tables for the pressure and temperature range supported by the Spycher and Pruess formulation are available in the PRT file and, in extended for, the DBG file.
  
  
• The existing Kvw table reporting for thermal CO2STORE models has been extended to provide all the above features.
  
  
• The AMF keyword can now be used to define enumerated initial conditions to isothermal CO2STORE models. The associated AMF reporting keywords and mnemonics are also now available, for both summary and 3D output.
  
  
• Improvements have been made to the K-value calculation in models containing NaCl and cells where extensive vaporization led to minimal amounts of liquid water present.
  
  
• Enhancements to defaulted SOLUBILT tables around robustness of pressure values.
  
  
• Reporting improvements to ZMF for CO2 in water-filled cells.

For both Eclipse 100 and Eclipse 300 simulators

• Internal logic has been improved to ensure that single processor parallel runs terminate cleanly.

For the Eclipse 100 simulator

• It is now possible to specify a restart file frequency of up to 999999.
  
  
• The keyword counter can now report values with more than 5 digits to support extremely large decks.
  
  
• An issue which could cause BASIC=0 in the RPTRST keyword to be ignored has been fixed.

For the Eclipse 300 simulator

• The mechanism handling parallel runs containing both coarsened cells and local grids has been improved.
  
  
• Field, and group history matched rate, vectors now report zero in cases where all wells are shut following a period of production.
