A method and apparatus for providing a local response to a local condition in an oil well are disclosed. A sensor (210) is provided to detect a local condition in a drill string. A controllable element is provided to modulate energy (205) in the drill string. A controller (175) is coupled to the sensor and to the controllable element. The controller receives a signal from the sensor, the signal indicating the presence of said local condition, processes the signal to determine a local energy modulation in the drill string to modify said local condition, and sends a signal to the controllable element to cause the determined local energy modulation.

La présente invention concerne un procédé et un appareil d'envoi d'une réponse locale à une condition locale dans un puits de pétrole. Un capteur est utilisé pour détecter une condition locale dans une colonne de forage. Un élément de régulation est prévu pour moduler l'énergie dans la colonne de forage. Un dispositif de commande est couplé au capteur et à l'élément de régulation. Le dispositif de commande reçoit un signal envoyé par le capteur, ledit signal indiquant la présence de ladite condition locale, traite le signal pour déterminer une modulation de l'énergie locale dans la colonne de forage afin de modifier ladite condition, puis envoie un signal à l'élément de régulation pour déclencher la modulation d'énergie locale déterminée.
