A method of fracturing a subterranean formation while drilling a well includes the steps of preparing a fluid useful for drilling a wellbore into the formation; drilling the wellbore into the formation with the fluid; acidizing the fluid such that the acid soluble additive is degraded; and fracturing the formation with the fluid in the wellbore to create a channel in the formation.

L'invention concerne un procédé de fracturation d'une formation souterraine lors du forage d'un puits comprenant les étapes consistant à préparer un fluide utile pour forer un puits de forage dans la formation ; forer le puits de forage dans la formation avec le fluide ; acidifier le fluide de façon à ce que l'additif soluble dans l'acide soit décomposé ; et fracturer la formation avec le fluide dans le puits de forage pour créer un canal dans la formation.
