Calculation observations
Gas FVF and stock-tank mass identities assume z=1.0 at the entered standard conditions.
Correlation-based black-oil and gas screening only; laboratory PVT, compositional EOS, water, wax, asphaltene, and near-critical phase behavior are excluded.

Oil: California-oil Standing source envelope is screened explicitly; regional bias is not corrected.
Gas: DAK is not a compositional EOS and standard-condition z is declared as unity.
