Abstract
Disclosed are downhole subassembly systems and method of use thereof. One downhole subassembly system is an orientable whipstock subassembly that includes a whipstock apparatus including a deflector surface operable to direct a cutting tool into a casing sidewall to create a casing exit, and an orienting sub comprising an upper coupling operatively coupled to the whipstock apparatus and a lower coupling at least partially engaged with the upper coupling and rotationally movable with respect thereto while in an un-collapsed configuration and rotationally fixed with respect thereto while in a collapsed configuration.
