Enhancements
1.    For DUALPORO=ECLIPSE, check that capillary pressures are provided for matrix relative permeability tables of dual-porosity grid cells, otherwise stop the run.
2.    When reading .INIT file, check if PORV or PORO arrays for active grid cells contain infinity values and reset these grid cells to inactive.
3.    If the ARRAYADD keyword results in a negative property value for a grid cell, reset the property value to zero.  

Bug Fixes

1. When reading MAPAXES, internal axes directions were not always calculated correctly due to bug introduced in v2026.0123 release. This could cause 3DSL to not properly locate well paths defined with X, Y, Z onto the CPG grid.

Bug Fixes

1. When reading an ECLIPEEGRID= file that contains the keywords NNC1, NNC2 and also contains TMULTNNC values of zero for the same NNCs, this could cause a crash when tracing streamlines across faults that have multiple NNCs. 

Enhancements

1. Added support for reading dual permeability grids when using the ECLIPEEGRID= and ECLIPSEINIT= keywords. However, dual permeability connections will be ignored.

Bug Fixes

1. When reading the keyword SIGMAV inside of a .INIT file and the file units were Field, the SIGMAV units were not handled correctly. 

Enhancements

1. Added CMG’s simulators keywords GRID and CORNERS for reading in CPG grids.

Bug Fixes

1. For CPG grids, when MAPAXES is not defined, recalculate the MAPAXES using coordinates of active grid cells only rather than relying on a correctly defined COORD plane.

1. Linking to Reprise License Manager libraries RLM17.11.
2. For SURVEILLANCE=ON forecast (a restart file has been read) runs , if a producer has HIST rates defined, these rates will only be used to calculated the total voidage rate of a producer.  The phase rates will still be calculated (forecasted) from the multi-phase wellbore inflow correlations that were computed from the timesteps with history prior to the restart file time.

Enhancements

1. Improved streamline tracing algorithm across faults in the X and Y directions when multiple non-neighbor connections are present.
2. NNC keyword allows to specify the absolute value of the transmissibility between two non-neighbor connections. This is needed for the case where their adjacent faces do not overlap and would otherwise result in a zero transmissibility.

Bug Fixes

Bug Fixes

1. For a well whose completions intersect active gridblocks, but at a later timestep had completions redefined that are all outside of the grid or in an inactive area of the grid, 3DSL retained the original completions.  Now 3DSL will warn that all completions are inactive and issue either a warning (WELLSNOBLKS=ON) or error (WELLSNOBLKS=OFF) if the well is opened.

Bug Fixes

Bug Fixes

1. Bug when writing out producer oil phase transmissibilities for MODEL=FCM or MODEL=BLACKOIL during a SURVEILLANCE=ON history run. Incorrect oil phase transmissibility then used during a  SURVEILLANCE=ON forecast run.
