LIVEOIL
Recognised by the OPM Flow parserRUNSPEC
This keyword activates oil, free and dissolved gas in the model and therefore makes the oil phase live oil88 “Live” oil is oil that contains gas in solution, which is normally the case for most conventional oil reservoirs. However, for oil reservoirs classified as heavy oil reservoirs, the in situ dissolved gas may be negligible and oil would then be classified as gas-free oil which is commonly referred to as “dead” oil. in the black-oil formulation, and is equivalent to setting the phases present in the model to be oil, dissolved gas, gas and water phases. Note if water is present in the model this needs to be explicitly stated via the WATER keyword in the RUNSPEC section (see also the BLACKOIL and DEADOIL keywords in the RUNSPEC section). The keyword is used by the commercial simulator’s compositional THERMAL option to set the phases present in the model.

This keyword is not supported by OPM Flow but has no effect on the results so it will be ignored.

Example
The following example activates the black-oil phases in the model.
--
-- ACTIVATE LIVE-OIL PHASE
--
LIVEOIL
Alternatively one could explicitly declare the phases using the following keywords in the RUNSPEC section.
--
-- OIL PHASE IS PRESENT IN THE RUN
--
OIL
--
-- DISSOLVED GAS IN LIVE OIL IS PRESENT IN THE RUN
--
DISGAS
--
-- GAS PHASE IS PRESENT IN THE RUN
--
GAS
--
-- WATER PHASE IS PRESENT IN THE RUN
--
WATER
The above example switches on the oil, dissolved gas, gas and water phases in the model.Manual source: parts/chapters/subsections/5.3/LIVEOIL.fodt
