- Abstract : The invention relates to a method for dynamically determining at least
one physicochemical property and the composition of a multiphase fluid flow in a
porous medium, including: constructing a geological model of said porous medium
and discretizing the model into basic cells; determining an initial status of each
cell, including determining the composition of said cell; and determining a change,
in at least one cell and during at least one predetermined time interval, in at
least one physicochemical property and in the phase composition of said fluid in
each component, comprising at least one step of determining an equilibrium within
said cell, including the use of at least one neuronal network to determine characteristics
that are in equilibrium in said fluid from the characteristics thereof that are
out of equilibrium.
