NET_FLAG Flag to identify all levels which satisfy cutoff criteria related to the potential of the rock to be a reservoir, independent of actual hydrocarbon producibility; typical cutoffs are porosity and clay content.
NET_PAY_FLAG Flag to identify all levels which satisfy cutoff criteria related to hydrocarbon producibility, often obtained by applying a saturation cutoff after cutoffs for porosity and mobility have already been applied (see NET_FLAG).
