Abstract:
A technique facilitates the drilling of deviated wellbores. A steerable drilling system is formed with a pair of components pivotably mounted with respect to each other. A removable strike ring is mounted to one of the steerable drilling system components and is positioned to engage a corresponding strike ring in a manner which limits the maximum pivot angle between the steerable drilling system components. By interchanging the removable strike ring with other removable strike rings, the maximum pivot angle can be adjusted in the field to accommodate drilling of a wider variety of deviated wellbores.
