Abstract: Influence of Fault Architecture on Fluid Flow: A Comparison Between Faults in Dolomite and Aeolian Sandstone.

MOLLEMA, PAULINE N., Terra Porosa; MARCO ANTONELLINI, Amoco.

Summary

We compare the geometry, architecture and petrophysical properties of faults in aeolian sandstone and faults in dolomite. Our comparison is based on observations of aeolian sandstone outcrops in Arches National Park, and in the East Kaibab Monocline Utah, and dolomite outcrops in the Sella Group, Northern Italy. We consider the surface outcrops as a natural analog for faulted reservoirs. The faults have a wide range of offsets, from a few millimeters to hundreds of meters. The observations show that sealing or migration potential of faults is strongly dependent on the throw, the type of associated structures in the damage zone and the distribution of faults. Fault architecture is strongly influenced by lithology.
