Abstract
An unconventional perforation tunnel stability analysis is conducted in this work by separating the role of two independent factors upon sand production: one is the well pressure, and the other is the 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 poroelasto-plastic materials allowed repeated calculations for a parameter sensitivity study. The results obtained should be used on a qualitative basis because of some degree of simplification.
