Whipstock with bottom-set mechanical anchor (KOYAM) Impact on metal

The whipstock with a mechanical single-die anchor is designed for setting inside the drill string and casing exit through one or multiple casings. To reduce impact of shock and bending loads during casing window milling, the Impact on Metal system is run in conjunction with the starting mill (SM) – Impact on Metal and the watermelon mill (WM) – Impact on Metal. This combination enables whipstock setting, window milling and drilling the rathole in a single trip. The system is mechanically set on bottom on a cement plug or bridge plug.
