Cemented whipstock KOC
The whipstock with cemented anchor is designed to deviate the drill bit from the original open hole axis during casing window milling and rathole drilling. The system is run in conjunction with a starting mill (SM) and a watermelon mill (WM). Installation is performed by mechanically setting the assembly on bottom, followed by cementing the anchor.
