Dual Section Mill
Archer developed the Medusa® multi-string section milling technology to deliver downhole windows through multiple casing strings for the installation of permanent well barriers. Medusa® is a hydraulically expandable section milling tool with a high expansion ratio (difference between fully collapsed and fully expanded). The expansion ratio of Medusa® enables it to mill through multiple consecutive strings of casing, eliminating chances of SCP and providing a suitable window for a permanent rock-to-rock or encapsulated well barriers. The patented design dynamically stabilises itself within the casing ID, leading to a precise cutout and improved milling performance.
