Invasion Percolation of Fluids into Active Faults using a Cellular Automaton Model
Fluids exert a strong control on the rheology of the earth's crust
under natural conditions and can even trigger earthquakes during the
filling of dams, hydrocarbon extraction or in the production of
geothermal energy. The aim of this project is to model the effect of
fluid channelling on earthquake faults using a cellular automaton
comprising a heterogeneous 'elastic brittle' fault surface overlain
and coupled to a lattice gas automaton representing local fluid
pressure. The problem is to couple the effect of the invasion
percolation of fluids from below while simulataneously stressing the
modelled fault. The project builds on an earlier 'dry' fault
simulation carried out under the same scholarship programme, which has
led to several publications.
