Abstract: Interest in heattransport in porous media has increased because of its many applications such use as tracer or in geotechnical engineering solutions. Understanding of the physical processes and parameters determining heattransport is therefore important. In this paper, heattransport is studied during a shallowheatinjection and storage field test. The test is simulated using SEAWAT. Sensitivityanalyses and collinear diagnostics are used to derive which parameters can be derived from the test and how reliable these values are. Heattransport during the test is compared with heattransport in the surficial zone at the same field site to compare parameter values. The most sensitive parameter is the thermal conductivity of the solid followed by the porosity, heat capacity of the solid and the longitudinal dispersivity. This indicates the predominance of conductive transport during the storage phase over the convective transport during the injection phase. Whereas heattransport in the surficial zone is insensitive to the longitudinal dispersivity, this parameter must be included to simulate the field test. This indicates that dispersivity cannot be ignored simulating convective heattransport in aquifers.
