Abstract[English]
A method comprises measuring, at a surface of a wellbore during drilling of the wellbore, at least one drilling operational parameter and determining at least one at-bit model parameter, at a drill bit used for drilling the wellbore, based on the at least one drilling operational parameter measured at the surface of the wellbore. The method comprises determining a drilling efficiency based on the at least one at-bit model parameter.[French]
Un procédé consiste à mesurer, au niveau d'une surface d'un puits de forage pendant le forage du puits de forage, au moins un paramètre opérationnel de forage et à déterminer au moins un paramètre de modèle au niveau du trépan, au niveau d'un trépan utilisé pour forer le puits de forage, sur la base du ou des paramètres opérationnels de forage mesurés au niveau de la surface du puits de forage. Le procédé comprend la détermination d'une efficacité de forage sur la base du ou des paramètres de modèle au niveau du trépan.
