Whipstock with mechanical retrievable bottom-set anchor (KOYAIM2)
The whipstock with a retrievable mechanical double-die anchor is designed for casing exit through one or multiple casings. The whipstock system - comprising a starting mill (SM) and a watermelon mill (WM) - enables whipstock setting, casing exit and rathole drilling in a single trip. The system is mechanically set on bottom on a cement plug or bridge plug. The anchor can be retrieved from the wellbore if necessary.
