Patent

CA 2225762

The present invention provides methods of delaying the destruction of a well as a result of the movement of a subsiding subterranean rock formation penetrated by the well bore. In accordance with the methods, a slot is cut into the subterranean formation in a direction opposite the direction of movement of the formation towards the well bore whereby the well bore extends through the slot as the subterranean formation moves.

La présente invention offre des méthodes qui permettent de retarder la destruction d'un puits par suite du déplacement de la formation rocheuse souterraine qu'il traverse. D'après ces méthodes, une fente est pratiquée dans la formation souterraine en direction opposée à celle du déplacement de ladite formation en allant vers le puits; de cette manière, le puits se prolonge dans la fente au fur et à mesure que se déplace la formation.
