The pvt interface is extended to handle wet-gas systems:
1. rvSat is added as a function in the PVT interface
2. SinglePvtLiveGas computes the pvt values and its derivatives
3. The old rbub variable is changed to rsSat for clearity
4. The new interface is tested in test_blackoilfluid with data from
liveoil.DATA and wetgas.DATA
our policy is that we only use boost if necessary, i.e., if the oldest
supported compiler does not support a given feature but boost
does. since we recently switched to GCC 4.4 or newer, std::shared_ptr
is available unconditionally.
The current implementations of IncompPropertiesInterface are very
all-or-nothing. In some situations, you want to read rock and fluid
properties from an Eclipse file, but use analytical functions for
the unsaturated properties. Or you want to update properties based
on a marching filter.
This patch provides a way to mix various property objects, or to
"shadow" the properties with a raw array of data, so you don't have
to reimplement the entire interface just to make a small change.
The numbers in the deck are more indicative of FIELD unit conventions
than METRIC unit conventions, so allow the input parser to interpret
the data in that manner.
