heal.abstract	Sand production experiments run on outcrop and reservoir cores reveal that the cavity of hollow cylinders fails in three distinct patterns depending on the sandstone type. The sandstones are classified according to the cavity failure pattern in three classes, (i) Class A - Brittle, (ii) Class B - Ductile, and (c) Class C - Compactive. Criteria are established for the classification of sandstones on data that are often available, such as data from uniaxial/triaxial tests and/or petrophysical tests. Sand measurement results show that the failure type has a direct consequence on the observed sand rate. Class A shows rapid sand rate increase with increasing stress, Class B shows a slow down period after initial sand production and Class C shows a slow increase of sand rate with increasing stress. The sand mass measurements and the sandstone classification were used for the development and calibration of improved analytical functions for sand mass quantification under given in situ stress conditions and production scenarios. © 2008, ARMA, American Rock Mechanics Association.	en
