A continuum theory for erosion in granular media

 

A continuum theory for erosion in relation to the sand production problem in reservoir sandstones is presented. The theory regards the continuum as a three—phase medium and establishes a set of mass balance equations for the various phases. The solution of the problem requires an additional equation in the form of a constitutive or evolution law. Two laws are proposed in order to reproduce experimental evidence of a decreasing over time sand production rate.
