Is it really difficult to get the data (from the field) on the pressure-interval (with the lower and upper limits) required for a near-miscible flooding as against the easier single-point pressure data required for the Miscible Flooding?

Well, I THINK SO.
The exact conditions for achieving miscibility are reservoir-specific because flooding a reservoir with water or gas base must meet a specific combination of conditions defined by reservoir temperature, reservoir pressure, injected gas composition, and oil chemical composition. For example Impurities in the injected CO2 stream in a CO2-EOR project could hinder the ability of the injected fluid to meet the criteria for achieving miscibility
