Bug Fixes

1. For SURVEILLANCE=ON and MODEL=FCM runs, the simulated oil, water, gas rates were not always properly matching the historical oil, water, gas rates for producers.

Bug Fixes

1. When extracting the FPMap and injector efficiencies from ECL/IX flow simulations, the well voidage rates were being ignored due to bug introduced in v2018.0901 release.  This gave incorrect IE plot and no changes in the injector/producer well rate targets within floodOPT.  Any floodOPT project based on a *_slx.dat run since 2018.0901 needs to be rerun with 3DSL and the refreshed in the floodOPT project. 

Bug Fixes

1. For SURVEILLANCE=ON models, the efflux fluid rates and cumulative volumes being reported were incorrect. Material balance errors being output were incorrect and not using the actual well injection and produced volumes.  3DSL now reports the correct material balance errors.
2. For ECLIPSEINIT= files that have the NNC keyword redefined compared with the NNC keyword in ECLIPSEEGRID= file, 3DSL was crashing due to a bug introduced in v2018.0901.

Bug Fixes

1. For SURVEILLANCE=ON models, the efflux fluid rates and cumulative volumes being reported were incorrect. The internal material balance was correct.
2. The keyword MULTPV inside of a .INIT file was not being applied to the final porevolume of each gridblock.

Enhancements

Bug Fixes

1. For SURVEILLANCE=ON models the simulated GOR for a producer cannot drop below RS.

Enhancements

Bug Fixes

1. Well porevolumes (to the .SMSPEC and .wpv files) were not being calculated for SURVEILLANCE=OFF models (bug introduced in the previous 3DSL release).
2. Thread bug when using SURFSIMPLE keyword.

Enhancements

1. The historical flow rates allocated to/from boundary and far-field connections are set to zero when output to the .WAF or .SLBUN files.

1. For SURVEILLANCE=ON, do not apply pattern material balance to gridcells where So<=Sor.
2. Can now read dual porosity grid files with the ECLIPSEEGRID and ECLIPESINIT keywords.
3. Keyword NNCEGRID to can be used to ignore all NNC’s defined in a .EGRID file.

1. When testing if TRANNNC was missing from a .INIT file, the test sometimes failed when it should not.
2. For SURVEILLANCE=ON, do not allow wells on group control.
