CO₂ and lean-gas MMP from three independent correlations, corrected for injectant impurities, with the spread between them shown rather than averaged away.

كيف تُحسب
- Cronquist (1978): MMP = 15.988 · T^(0.744206 + 0.0011038·MW_C5+).
- Glasø (1985) and Alston et al. (1985) give two further independent estimates from C7+ molecular weight, temperature and the volatile-to-intermediate ratio.
- Sebastian et al. (1985) corrects for an impure CO₂ stream through the mole-weighted critical temperature of the injectant.
- For nitrogen and lean hydrocarbon gas, Firoozabadi–Aziz is used instead — the CO₂ correlations do not apply to it at all.

أين تتوقف عن الصحة
These are correlations on a few hundred slim-tube tests, mostly on North American fluids, and the three of them routinely disagree by twenty per cent or more — which is why this tool shows the spread instead of a single number. None of them know anything about your crude beyond a molecular weight and a temperature. A slim-tube or rising-bubble measurement on the actual fluid and the actual injectant is the only number a project should be designed around; use this to decide whether that test is worth commissioning.
