Abstract
Abstract Although a well has hundreds of perforations, a single perforation is normally used for perforation interaction analysis assuming the perforations are shot symmetrically and the stress state around a perforation is symmetric in both vertical and horizontal directions. However, for the single/double spiral perforations shot in inclined wells, no vertical and horizontal symmetry surfaces exist. Required elements for multi-perforation model are more than 10,000, which results in complex mesh generation and long computation time. This study investigates perforation interaction to find the optimum perforation design which yields the highest productivity while maintaining mechanical stability.
