Bug Fixes

1. When SURVEILLANCE=ON:
   1. MODEL=BLACKOIL the HISTGAS rate was ignored if HISTFREEGAS=OFF.  Now only the free gas portion of HISTGAS rate is ignored.
   2. Minor changes to the calculation of well porevolumes for shared gridblocks between producers. This changes the material balance calculation results slightly, compared to the 2020.0528 release.
   3. Minor bug fixes when forecasting compressible surveillance runs.

Enhancements

Bug Fixes

Bug Fixes

1. Parallel compute bug when writing the .wpv file.  Might affect forecast runs when SURVEILLANCE=ON.
2. Bug fix in 1D-solver for compressible PVT flow simulation runs.
3. Bug fix when SLINES2= is present when writing to the .sl2 file.

Bug Fixes

1. Upon running 3DSL it could delete *.rst files of a different 3DSL run in the same folder if the two runs share the same rootname in a wildcard match up to suffix ‘.1234567.rst’ of the .rst name file.
2. The keyword WELTARGET in an Eclipse schedule file was not being ignored for wells on WCONHIST when converting from a .SCH to a .3dslrec file.

Bug Fixes

1. When translating a well path from X=, Y=, Z= to intersected gridcells (I,J,K) for CPG grids, intersected gridcells were not always found if the grid COORD lines were not vertical.  Also improved performance when searching the CPG grid and translating the wellpath.

Enhancements

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.

Enhancements

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.
