There is a sligth difference between the cell depth taken from the
centroid (opm) and a straightforward average of corner coordinates
(ecl). For the initialisation of Norne this causes some differences
when deciding cell center positions relative contact depths.
Model 2 partly uses PORO=0.0 to signal inactive cells. This PR
prevents such cells from causing unwanted zcorn modifications in
the current min-pv algoritm. (The problem is however more general as
zero PORO or NTG should kill a cell whether MINPV is active or not,
refer kw ACTNUM.)
- satfuncStandard: Unscaled curves, using standard version of the
Gwseg model.
- satfuncEPSBase: Unscaled curves, but using the EPS version of
the Gwseg model. There are some differences between this and the
standard version of Gwseg for derivatives at critical saturations.
The scheme for calculating the derivatives should be discussed.
(Will file a separate issue on this.)
- satfuncEPS_A: Scaled curves. Scaling parameters specified via
SWL family.
- satfuncEPS_B: Scaled curves. Scaling parameters identical to _A
but this time specified via the ENPTVD table. Test currently
suspended due problems with eclipse-state.
- satfuncEPS_C: Scaled curves. Scaling parameters identical to _A
but this time specified via Norne-like syntax (EQUALS, COPY etc.).
- Saturations, phase pressures, and standard initialsation of RS and RV
now agree to baseline.
- Tables of RS and RV versus vertical depth (kw RSVD RVVD) have been
hardcoded for testing (need new parser) and the calculations agree to
baseline in the gas and oil zones. In the water zone there is some
differences: Our code computes saturated RS and RV using the final
phase pressures (these are modified to be consistent with saturations
and capillary pressures) while the baseline uses unmodified phase pressures.
This commit implements some additional scaling keywords. This includes
the ISWL-family that provide hysteresis behaviour via alternative
scaling of the tables. The old parser has been somewhat extended for
testing purposes. The commit also includes a slight refactoring of the
SatFunc-family where a new base class has been introduced.
