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.

L'invention concerne une technique qui consiste à déterminer un tenseur des contraintes dans une formation qui entoure un puits de forage. Le tenseur des contraintes varie par rapport au puits de forage. La technique consiste à appliquer une charge perforante dans le puits de forage pour perforer la formation et, au moins, sélectionner la charge perforante et l'orienter dans le puits de forage selon, à tout le moins, la détermination du tenseur des contraintes.
