How to specify EQUIL keywords given FWL and FOL for 3-phase run (no gas cap initially)

[jeosol]

Trying to specify EQUIL keywords for a 3-phase run OPM given free-water level (FWL), oil-water level (OWL), and PC in the imbibition and drainage curves. Also the reference depth and reference pressure are provided. There is no initial gas cap and all gas are dissolved (initially). A table of Psat vs depth is available via PBVD keyword.

The manual says EQUIL keywords accepts OWC depth and PC @ OWC as part of the input.

--RefDepth | RefPress | OWC | Pc@OWC | GOC | Pc@GOC | RSVD | RVVD | ...
   Depth     Pressure     ?      ?      0       0       1      0

In the EQUIL data above, the reference depth and reference pressure are provided at the FWL.

Questions:

1. Since there is no initial GOC, Is it okay to specify initial GOC as zero in the table

2. How to set the ? values in the EQUIL table

Also, does OPM allow initialization with drainage Pc (drainage relperms) and use imbibition relperms in production and waterflood.
