Apparatus and associated methods of using provide the capability of forming an opening through a tubular structure disposed within a subterranean well. In a preferred embodiment, an apparatus has a cutting device disposed within a tubular housing and a displacement device for displacing the cutting device relative to the housing. Additional displacement devices may be utilized to combinatively permit axial, radial, and rotational displacement of the cutting device relative to the housing. Such displacement of the cutting device may be telemetry-controlled from the earth's surface.

Cette invention concerne un appareil et les méthodes associées pour former une ouverture dans une structure tubulaire disposée dans un puits. Dans une réalisation privilégiée, l'appareil comporte un dispositif de coupe disposé à l'intérieur d'un logement tubulaire et un dispositif de commande servant à déplacer le dispositif de coupe par rapport au logement. D'autres dispositifs de commande peuvent être utilisés pour permettre le déplacement axial, radial et tournant combiné du dispositif de coupe par rapport au logement. Ce déplacement du dispositif de coupe peut être commandé par télémesure à partir de la surface.
