- Abstract
- The hydrodispersive properties of porous
sediments are strongly influenced by the heterogeneity
at fine scales, which can be modeled by geostatistical
simulations. In order to improve the assessment of the
properties of three different geostatistical simulation
methods (Sequential indicator simulation, SISIM; Transition
probability geostatistical simulation, T-PROGS; Multiple
point simulation, MPS) a comparison test at different scales
was performed for a well-exposed aquifer analogue. In the
analysed volume (approximately 30,000m
3
) four operative
hydrofacies have been recognised: very fine sand and silt,
sand, gravelly sand and open framework gravel. Several
equiprobable realizations were computed with SISIM, MPS
and T-PROGS for a test volume of approximately 400m
3
and
for the entire volume, and the different outcomes were
compared with visual inspection and connectivity analysis of
the very or poorly permeable structures. The comparison of
the different simulations shows that the geological model is
best reproduced when the simulations are realised separately
for each highest rank depositional element and subsequently
merged. Moreover, the three methods yield different images
of the volume; in particular MPS is efficient in mapping the
geometries of the most represented hydrofacies, whereas
SISIM and T-PROGS can account for the distribution of the
less represented facies. (literal)
