New Software Release

ECLIPSE 2018.2 Now Available

Wednesday, 19 December 2018

Release highlights

ECLIPSE 2018.2 development has focused on the improvement of existing functionalities in two areas: usability and client requested enhancements. User permeability can now be defined in J-Function to enable workflows such as sensitivity study of permeability for history matching without affecting the fluid in place. ECLIPSE 2018.2 delivers several enhancements based on customer feedback, including performance improvement, large model management, and well controls.

Key developments

Workflow and Usability

  • User-permeability for J-Function

For ECLIPSE 100, you can now define the permeability values to be used for J-Function by using the PERMJFUN keyword and setting the permeability direction to ‘U’ in the JFUNC or JFUNCR keywords. In the Define simulation case process in Petrel 2018.2 and later, you can supply a grid property as the J-Function permeability. This enables you to run many new workflows, such as creating a sensitivity study of permeability for history matching while fixing the fluid in place with PERMJFUN.

Enhancements

ECLIPSE 2018.2 contains several changes to address issues discovered in previous releases, as part of our ongoing commitment to improving ECLIPSE.

  • For ECLIPSE 100, the interaction of WCONPROD and WELDRAW has been improved when rate limits are set using user-defined quantities to ensure that the latest value of the User Defined Quantities UDQ is always applied.
  • For ECLIPSE 100 in parallel, use of the COMPRESS option in the RPTRST keyword now exports well connections from all processes.
  • For ECLIPSE 100 in parallel, the user-defined connection quantity algorithms have been further refined to improve behavior for wells crossing parallel boundaries in any direction.
  • For ECLIPSE 100, an issue which could make the simulator unresponsive for an extremely long time if it tried to take a large timestep immediately after a well is switched to a Generalized Pseudo Pressure model (GPP) has been fixed.
  • For ECLIPSE 300, the behavior of modifications of the SIGMA or SIGMAV keyword in the SCHEDULE section was not as expected. This has been corrected.
  • For ECLIPSE 100 in parallel, the workspace size calculation has been improved to ensure that enough is allocated for very large models using the threshold pressure option.
  • For ECLIPSE 100, the SUMTHIN keyword was not working correctly when specified in the SCHEDULE section. This has been corrected.

Target audience

ECLIPSE: Reservoir engineers involved in production forecasting, reserves estimation, field development planning, or reservoir management.

FrontSim: Geoscientists and reservoir engineers performing geological model screening and ranking or pattern flood management.

Commitment to quality

Schlumberger has the commitment to continuously develop ECLIPSE industry-reference reservoir simulator, which has more than three decades in the market and has been used by almost all operators and service companies around the globe. ECLIPSE simulator is positioned as the industry reference simulator used to predict and plan field production strategies. It is important to highlight the continuous commitment from Schlumberger to support and enhance the ECLIPSE simulator.
