An unconventional perforation-tunnel stability analysis is conducted in this work by separating the role of two independent factors on sand production: well pressure and local pressure gradient around a cavity. Such a separation clarifies most of the phenomena observed during sand production in oil fields. Simple analytical solutions for poroelastoplastic materials allowed repeated calculations for a parameter sensitivity study. The results obtained should be used qualitatively because of some degree of simplification.
