[Géométrie des puits horizontaux.] Le rayon de courbure de la partie de trajectoire qui relie la section verticale à la section horizontale dépend de plusieurs facteurs : - le déplacement horizontal recherché entre la localisation en surface et l'entrée dans le réservoir, - la position verticale du début de la déviation («kick-off point»), - la longueur de drain horizontal à forer, - les contraintes de complétion. D'une manière générale les longs rayons de courbure, supérieurs à 250 mètres, permettent de forer de plus longues sections horizontales et facilitent la complétion. Les longs rayons de courbure sont surtout utilisés pour les puits de développement alors que les courts rayons s'appliquent essentiellement aux opérations de recomplétion. 1, record 8, French, - rayon%20de%20courbure
