Abstract
A milling-drilling section billet and anchoring device that is an improvement over current technology. The invention provides a device that incorporates an aluminum milling-drilling section billet and an anchoring device. The assembly is segregated into three main functional components: a setting tool connector system, an aluminum billet, and an anchoring section. The anchoring section has two slips, offset laterally and positioned 180 degrees apart on the device. When deployed, the slips lock the device in the formation and produce an offset of the billet within the formation. This angular positioning allows a milling head to be moved in a new direction from the existing well formation. Once the device is properly positioned in the wellbore, a frangible member breaks to allow removal of the setting tool prior to the renewed drilling operation.
