In order to facilitate management of large scale gas miscible EOR proj
ects, a software package called FAME (Forecast Analyser for Miscible E
OR) has been developed based on an analytical approach. The primary ro
le of the software is to provide pool-wide performance predictions fro
m mechanistic dis placement characteristics determined either by part-
pattern numerical simulations, or by preliminary history matching of f
ield data. The notable features incorporated into the software are tha
t: (1) important flood parameters, such as pattern allocation factors,
solvent distribution and sweep, are dependent on pool-wide fluid move
ment and pattern interactions, which in: turn are dependent on the inj
ection/production sequence of historical and planned flood operations,
(2) crucial physical mechanisms associated with the gas miscible EOR,
such as gravity override, solvent and chase gas miscibility with rese
rvoir oil, and miscible and immiscible displacement processes are adeq
uately represented, and (3) results of mechanistic numerical simulatio
ns or history-matching past field data can be mimicked through variati
ons of a small number of parameters. The software has impacted the man
agement of the Judy Creek hydrocarbon miscible projects with the achie
vement of a successful history match and the provision of useful infor
mation related to flood performance.
