A method and system used for testing a subterranean well. A sensor (34), such as a distributed temperature sensor, comprising a sensing optical fiber (48) connected to an interrogation unit (50), is deployed together with a drill stem test string (20) so that the sensor extends below the packer of the drill stem test string and across at least one formation (22) of the wellbore.

L'invention concerne un procédé et un système utilisés pour réaliser des essais dans un puits souterrain. Un capteur (34), tel qu'un capteur de température réparti, comprenant une fibre optique de détection (48) reliée à une unité d'interrogation (50), est déployé avec un train de tiges d'essai de forage (20) de sorte qu'il s'étende en dessous de la garniture d'étanchéité du train de tiges d'essai de forage et à travers au moins une formation (22) du puits de forage.
