oxygen transport inside the matrix. It is obvious that a poorly permeable matrix could
not favour oxygen transport with further combustion front extinction.
Along the tube, the high temperatures decrease the oil viscosity, and then due to a
pressure gradient between matrix and fracture, a significant amount of oil is expelled
from the matrix to the fracture region close to the combustion front (see Fig.

).
5 Concluding Remarks
A mathematical model, for ISC at lab-scale, was numerically solved for a
matrix-fracture system. The model was based on a benchmark case for a homo-
geneous system, which was validated with experimental data, obtaining good agree-
ment. The matrix-fracture system presents fluids breakthrough due to the phases and
