3DSL v2020.0723 on 07/23/20

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

1. Added keyword VERRMULT to control the fraction of volume error that is included in the pressure solve for compressible SURVEILLANCE=ON runs.
