Measurements made using at least one two-component magnetometers on a rotating bottomhole assembly are processed to correct for disturbance of the magnetic field due to the rotating drillstring and get an estimate of instantaneous toolface angle.

Les mesures effectuées au moyen d'au moins un magnétomètre à deux composants sur un ensemble fond de puits rotatif sont traitées pour corriger les perturbations du champ magnétique dues à la rotation du train de tiges et obtenir une estimation de l'angle d'attaque instantané.
