Enhancements.

Enhancements

1. Support the Eclipse keywords PRESSURE, ECHO/NOECHO in the INITIALCOND section of a 3DSL input file.
2. Echo the values of NX,NY,NZ to the .eco file once the GRID section is parsed.
3. If using the ECLIPSERST= in the INITIALCOND section, update the paths to the base restart file so that studioSL can find the base run.
4. When reading ECLIPSEEGRID=, if MAPUNITS is missing default the value to the setting of UNITS=.
5. Improved KRWO and KRGO tables echoed to the .eco file.

Bug Fixes

Enhancements

1. When reading files supplied with the keywords ECLIPSEINIT= and ECLIPSERST=, 3DSL now supports grid property arrays in expanded (all cells) format.

Bug Fixes

1. When reading an ECLIPSEEGRID= file that contains NNC's, but the ECLIPSERST= file does not contain fluxes for the NNC's (such as FLROILN+), 3DSL now issues an error instead of crashing.

Enhancements.

1. When extracting SL's from Eclipse simulations, NNC's defined for parallel compute regions, are now supported.
2. Echo the capillary pressure information to the .eco file if ECOFILE=ON in the RELPERMS Section.
3. Reduced time to read successive timesteps in the ECLIPSERFT file, if supplied.еК

Bug Fixes.

Enhancement.

1. If NaN is detected at the end of a timestep, stop simulation and exit 3DSL with error code -1.

Bug Fixes.

1. Injection composition assigned to an injector group was not being updated if the composition was changed at a later TIME period.

This is the first major release of 3DSL since v4.10 and contains numerous behavioral changes.еК 3DSL is now compiled with the latest Intel compiler 14.x and the SAMG (Algebraic Multigrid Methods for Systems) matrix solver has been upgraded to v27a1p6. Streamsim has also taken this opportunity to add new functionality to initialization, transmissibility calculations, tracing routines and parallel-compute regions of runtime code.еК

Enhancements.

1. For surveillance models, if HISTFREEGAS=OFF, wells will produce at their historical liquid voidage rates and produced gas will be ignored.

Bug Fixes

1. For surveillance models, phase fluxes at boundaries were not being calculated correct at surface conditions when Rs/=0.
2. For surveillance models, historical voidage rate was not always being honored.

Enhancements

1. Added the keyword STOPSIMTIME= to the RUNOPTIONS section.

Bug Fixes

1. For a well on group control that violates its rate limit, switch the well to that rate limit and remove from guided group control but include well‰ЫЄs rate as part of the group constraint.
2. When reading a .sgrid file, well paths defined using X=,Y=,Z= were not calculated to intersect the grid, when in fact they were.

Enhancements

Bug Fixes

1. Added check that a group constraint must be defined if a well for the given group, is put on group control.еК Previously 3DSL would crash if the constraint was not defined.

2. For multi SATNUM models, if all phase relperms are zero during the calculation of gridblock phase transmissibilities, the will be reset to a TINY number to avoid divide-by-zero.

Enhancements

1. 3DSL will create an ASCIIеК*.cvs file containing field level production, injection, andеКinsitu data at each timestep for all chemical components defined.еК This data is already written to the *.SMSPEC file.

Bug Fixes

1. When reading ECLIPSEINIT= files, force "normal" connections based onеКnon-zero TRANX values even if MULTX=0 for the connection.
2. When writing CHAR stype keywords to theеКECL style files, skip writing array contents if array length=0.еК
