Quantitative Analysis of the Effect of Perforation Interaction on Sand Production Using the Finite Element Method

Abstract

The study investigates perforation interaction in order to find the optimum perforation design which yields the highest productivity while maintaining mechanical stability. The study is composed of i) evaluation of flow performance and ii) evaluation of mechanical stability. Both evaluations were performed by using the finite element method with multi-perforation mesh to distinguish the effect of perforation interaction. The flow evaluation quantitated the productivity for various cases, allowing us to find the most prolific perforation design. In the stability evaluation, perforation stability was quantitated under various conditions with the effect of perforation interaction. It provides us with a new insight into the effect of shot density on perforation stability.
