Abstract
A technique includes determining a stress tensor in a formation that surrounds a wellbore. The stress tensor varies with respect to the wellbore. The technique includes running a perforating charge into the wellbore to perforate the formation and performing at least one of selecting the perforating charge and orienting the perforating charge in the wellbore based at least in part on the determination of the stress tensor.
