Whipstock with hydraulic-mechanical retrievable sealing anchor set without bottomhole support KOYAGMIG
The whipstock, equipped with a hydraulic-mechanical retrievable anchor and an integrated sealing packer (eliminating the need for additional sealing of the mail hole), is designed for milling a casing window through single 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 whipstock is hydromechanically set without cement bridge or packer plug. The anchor can be retrieved from the wellbore if necessary.
